The 2022 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. It was an above-average season in terms of depressions and average in terms of deep depressions, but below average in terms of cyclonic storms. It was also the least deadly North Indian Ocean cyclone season since 1988, according to official data. The season's strongest tropical cyclone was Cyclone Asani, with maximum wind speeds of 100 km/h (65 mph) and a minimum barometric pressure of 982 hPa (29.00 inHg). The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with the peak from May to November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.
The scope of this article is limited to the Indian Ocean in the Northern Hemisphere, east of the Horn of Africa and west of the Malay Peninsula. There are two main seas in the North Indian Ocean — the Arabian Sea to the west of the Indian subcontinent, abbreviated ARB by the India Meteorological Department (IMD); and the Bay of Bengal to the east, abbreviated BOB by the IMD.
The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center (JTWC) releases unofficial advisories. On average, three to four cyclonic storms form in this basin every season. [1]
The season began with BOB 01 which formed on 3 March over the Bay of Bengal. [2] It peaked as a deep depression, [3] before weakening as a well-marked low-pressure area on 6 March. [4] The system became the eighth system to form in March since reliable records began in 1891. [5] On 20 March, another deep depression classified as BOB 02 formed in the Andaman Sea. BOB 02 made landfall in Myanmar before dissipating. After more than 1 month of inactivity, a low-pressure system formed off the coast of Andaman and Nicobar Islands on 6 May. On the next day, JTWC classified it as Tropical Cyclone 02B, followed by IMD which recognized it as Depression BOB 03. The depression intensified into a cyclonic storm, named Asani, making it the first named storm in the season. Soon, Asani was upgraded to Category 1 cyclone by JTWC, and IMD upgraded to a severe cyclonic storm. Afterward, Asani began to weaken rapidly due to high wind shear. and made landfall in Andhra Pradesh as a deep depression. Later in May, BOB 04 quickly consolidated into a depression as it landed on the south Burmese coast.
Activity ceased for approximately 2 months before Depression ARB 01 was designated and struggled against strong wind shear and dry air intrusions. In August, four systems were designated by the IMD. Land Depression 01 was short-lived and degenerated to a remnant low over Chhattisgarh. Depression ARB 02 formed a couple of days later and even though the IMD kept the system as a depression, the JTWC upgraded ARB 02 to Tropical Cyclone 03A. Having a tropical storm-force cyclone form in the Arabian Sea in August is rare, and the last system to become one was Cyclone Aurora in 1983. Depression BOB 05 followed and the brown ocean effect aided the system to maintain depression status for a few more days. After BOB 05, Deep Depression BOB 06 was designated by the IMD after the JTWC unofficially upgraded it to Tropical Cyclone 04B due to attaining tropical storm-force winds. BOB 06 later made landfall in Digha, West Bengal and caused 32 deaths. In September, the IMD briefly designated Land Depression 02.
In late October, the IMD monitored an area of low pressure, which was designated as BOB 07 and later became Cyclonic Storm Sitrang, officially the second named storm of the season. The cyclonic storm abruptly headed north-northeast and early on October 24, it made landfall in Patuakhali, Bangladesh. Sitrang is the first tropical cyclone to hit Bangladesh since Cyclone Mora in 2017, and caused 35 fatalities. After Sitrang, Depression BOB 08 formed and struggled to consolidate a well-defined center before causing minor impacts to parts of southern India. In December, Deep Depression BOB 09 formed. IMD later upgraded it to Cyclonic Storm Mandous. Despite moderate easterly mid-level wind shear, Mandous intensified to a Severe Cyclonic Storm as it neared Sri Lanka. It made landfall near Chennai, India, as a Deep Depression and caused 9 deaths. The remnants of Mandous transferred across southern India and into the Arabian Sea. The system quickly developed and was designated as Depression ARB 03 by IMD. The storm unexpectedly rapidly developed and the JTWC designated it as Tropical Cyclone 07A, peaking with winds of 60 mph (95 km/h). After ARB 03, Depression BOB 10 formed and meandered in the Bay of Bengal before dissipating.

Towards the end of February, a cyclonic circulation formed over the Strait of Malacca and the adjoining Andaman Sea, [6] which later intensified into a low pressure area on midday (17:30 IST) of 28 February, as the disturbance formed a low-level circulation, according to a INSAT-3D satellite imagery. [7] [8] Early the next day, at 09:00 UTC (14:30 IST), the disturbance further intensified into a well-marked low pressure area, as it developed a defined cyclonic vortex, [9] and three-and-a-half-hour later, the United States-based Joint Typhoon Warning Center (JTWC) started monitoring the same disturbance as Invest 90B. [10] On 3 March of midnight (05:30 IST), the well-marked low organized to a depression and the India Meteorological Department (IMD) identified the system as BOB 01, making it the first system of the season. [2] This intensification was possible because of a favourable Madden–Julian oscillation (MJO) phase, along with a feeble easterlies outflow. Additionally, sea surface temperatures (SST) of 27–28 °C (81–82 °F) were warm enough for tropical cyclogenesis to take place, along with moderate to high vertical wind shear. [2] During the next day, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) on the system. [11] The depression subsequently intensified into a deep depression, [3] and by 21:00 UTC (02:30 IST), the JTWC started initiating advisories for Tropical Cyclone 01B. [12] After maintaining its intensity for a day, the JTWC issued its last warning for the system, at 15:00 UTC (20:30 IST) as the increasing dry air had weakened its convective mass. [13] The IMD subsequently weakened back to a depression due to the same reason. [14] On 6 March, the IMD issued its last advisory for the system and downgraded it to a well-marked low pressure area, as its convective mass got further disorganized by the wind shear. [4]

In mid-March, a low-pressure area formed in the southwest Bay of Bengal, offshore of Sri Lanka, which later intensified into a well marked low pressure area, and the JTWC started monitoring the disturbance as Invest 91B. [15] [16] [17] It meandered east-southeast for three days, and on 20 March, the IMD reported that a depression formed over the Bay of Bengal, giving it the designation BOB 02. [18] On that day, the JTWC issued a TCFA for the system. [19] The system gradually intensified, into a deep depression by 00:00 UTC (05:30 IST) the next day, [20] as the convection had further organized favorable conditions such as moderate to high sea-surface temperatures. [20] On 22 March, the JTWC cancelled the TCFA due to the land interaction in Myanmar until the landfall. [21] [22] BOB 02 rapidly weakened overland, degenerating into a depression [23] and by 03:00 UTC (08:30 IST) the next day the system weakened into a well-marked low pressure area and IMD issued last advisory. [24]

During the first week of May, a strong pulse of Madden-Julian Oscillation (MJO) and Equatorial Rossby wave (ERW) prevailed in this basin. These two conditions led to a cyclonic circulation forming over the southern Andaman Sea on 4 May. At the same time, a Westerly wind burst occurred on the same day which resulted in formation of twin cyclones over the either side of the Indian Ocean. The southern hemisphere counterpart being Tropical Cyclone Karim and the northern hemisphere counterpart being this cyclonic circulation. [25] [26] [27] The JTWC followed suit and designated it as Invest 92B on the next day. [28] On 6 May, under the influence of the same disturbance, a low pressure system formed off the coast of Andaman and Nicobar Islands. [29] Subsequently, the JTWC issued its TCFA, as it had rapidly consolidated its convective structure for the past few hours, along with development of a well-defined low-level center. [30] By the morning of 7 May, the system became more well-marked over the same region. [31] At 09:00 UTC (14:30 IST), the JTWC initiated advisories on the system and classified it as Tropical Cyclone 02B, while IMD followed the suit and upgraded it to Depression BOB 03. [32] [33] Three hours later, the system was further upgraded to a deep depression status by the IMD, after forming a defined central dense overcast cloud pattern. [34] By 05:30 IST (00:00 UTC) of the next day, the system organized into Cyclonic Storm Asani, becoming the first cyclone of the season. [35] The name Asani was provided by Sri Lanka, which means wrath in Sinhala language. [36] [37] Nine hours later, the JTWC upgraded it to a Category 1 status. [38] At 12:00 UTC (17:30 IST), the IMD further upgraded it to a severe cyclonic storm, as microwave imagery showed a well-organized system. [39] On 10 May, the cyclone began to encounter high wind shear due to which the JTWC downgraded it as a tropical storm while the IMD continue to maintain it as a severe cyclonic storm. [40] [41] it began to make a sudden westward jog and mild decrease in wind shear made the JTWC to upgrade it again into a Category 1-equivalent tropical cyclone. [42] Nine hours later, Asani was further downgraded into a tropical storm, it began to weaken rapidly due to higher wind shear as well as dry air intrusion. [43] On 11 May, 12:00 UTC, Asani further weakened to a Deep Depression as it made landfall in the Indian State of Andhra Pradesh. The next day, the IMD issued its last advisory as the system degenerated into a low pressure area.

A fresh cyclonic circulation developed on early 19 May, over the Gulf of Martaban, due to the enhancement of the annual South-West monsoon over the basin. [44] [45] By the evening, under the influence of that circulation, a low pressure system spawned over the same region. [45] At 18:00 UTC (23:30 IST), the JTWC also acknowledged that same circulation at the night of the same day. [46] By 00:30 UTC (06:00 IST) the JTWC published its TCFA for the system after it had rapidly consolidated its convective structure for the past few hours, and also formed a well-defined low-level center. [47] But eight hours later, the JTWC, cancelled it because its close proximity over land. [48] However, according to IMD, it rapidly consolidated into a well-marked low pressure area in the morning of the same day, and further into a depression at 11:30 IST (03:00 UTC), as it moved northeastwards, towards the south Burmese coast. [45] Between 08:00 UTC (13:30 IST) and 09:00 UTC (14:30 IST), the system made landfall over the southern Burmese coast, 30 km (20 mi) from Mawlamyine. [49] The system maintained its depression status as it travelled inland. [50] [51] By 00:00 UTC (05:30 IST) the next day, the system finally weakened into a well-marked low pressure area over the Burma-Thailand. [52]
The system helped the monsoon to further advance into parts of southern Arabian Sea, southern parts of Maldives and parts of southern and east-central Bay of Bengal. [53]

On 15 July, the JTWC started monitoring a disturbance west of Jafrabad, Gujarat, and it was unofficially designated as Invest 96A. [54] The disturbance substantially deepened, early on the next day, which prompted JTWC to upgrade it chance of formation to medium. [55] At 03:00 UTC of the same day, the IMD noted the disturbance and upgraded it to a tropical depression, becoming the first tropical depression of the season in the Arabian Sea. [56] It peaked as a depression, with maximum sustained wind speed of 25 kn (45 km/h; 30 mph) and a minimum barometric pressure of 992 hPa (29.29 inHg) after its initial stage of formation. [56] However, the system suffered from dry air intrusions as it moved away from the Indian coast. [57] By 18:00 UTC, the JTWC ceased tracking Invest 96A, [58] and on 18 July, the IMD issued its last warning, citing its weakening to a remnant low. [59]

A monsoonal low spawned over the northwestern region of Bay of Bengal, off the West Bengal and Odisha coast on midday of 6 August, which later concentrated into a well-marked low pressure area on the next day. [60] By 9 August, it concentrated into a depression, after moving over coastal Odisha due to the incoming monsoonal trade winds. [61] It managed to maintain its intensity overland, until at 00:00 UTC (05:30 IST) of 10 August, it was downgraded to a remnant low over Chhattisgarh and adjoining east Madhya Pradesh. [62]

After the dissipation of Land Depression 01, a sudden surge of equatorial Rossby Waves and Kelvin Waves prevailed over the basin. [63] These two waves helped in a formation of another monsoonal low over Saurashtra and adjoining northeastern Arabian Sea on 10 August, [64] which later concentrated into a well-marked low pressure on 12 August. [65] The JTWC, on the same day, designated it as Invest 98A. [66] By 12 August, favorable conditions like high sea-surface temperature (SST), moderate wind shear and a strong pulse of MJO, helped for further concentration into a depression, but its center was sheared due to wind shear. [67] The JTWC soon followed the suit and upgraded it to Tropical Cyclone 03A. [68] However, as it moved westwards away from the Indian coastline, the wind shear increased significantly, which decayed its convective structure. [69] [70] At 03:00 UTC (08:30 IST), the JTWC ceased issuing advisories to the system. [70] Nine hours later, the IMD followed the same, and downgraded the system to a remnant low. [71]

Under an influence of another cyclonic circulation, [67] a low pressure area formed over north Bay of Bengal on 13 August. [72] Substantially, it concentrated into a well-marked low pressure area on the same day. [71] After reaching near the coast of northern Odisha and West Bengal, it further concentrated into a depression at 03:00 UTC (08:30 IST) of 14 August. [73] The depression made landfall near Digha, West Bengal, two hours after its designation. [74] Brown ocean effect played a major role in the system's lifetime, as it managed to maintain its depression status over land for three days. Along with brown ocean effect, low vertical wind shear and moisture feeding monsoonal trade winds also helped to retain its intensity. [74] At 12:00 UTC (17:30 IST) of 17 August, the depression finally weakened into a well-marked low pressure over southwestern Rajasthan. [75] The system caused widespread heavy rainfall across Odisha, West Bengal, Jharkhand, Central India and Rajasthan. [76] [77] [78]

On 17 August, the JTWC recognized a newly formed low level circulation near Myanmar and designated it Invest 99B, which showed disorganized convective structure and an obscure low-level center. [79] By the next day, it developed into a low pressure area over northeastern Bay of Bengal and adjoining Bangladesh coast. [80] The JTWC unofficially released a TCFA for the system after its rapid development of its convective structure. [81] By the same day, at 21:00 UTC (02:30 IST), the JTWC unofficially declared it Tropical Cyclone 04B. [82] The IMD followed the same, and upgraded it to Depression BOB 06. [83] At 06:00 UTC (11:30 IST) on 19 August, BOB 06 further organized into a deep depression just off the coast of West Bengal and Bangladesh. [84] Shortly after intensifying, it made landfall close to Digha, West Bengal between 13:30 UTC and 14:30 UTC (19:00 IST and 20:00 IST) that same day. [85] At 21:00 UTC (02:30 IST), the JTWC issued its last advisory. [86] After landfall, the system continued to track west-northwestwards, eventually weakening into a depression on 21 August over northeastern Madhya Pradesh and southeastern Uttar Pradesh. [87] [88] The system persisted for another two days until 23 August, when it weakened into a well-marked low pressure area over eastern Rajasthan and adjoining northwestern Madhya Pradesh. [89]
A total of 32 cyclone-related deaths occurred due to the effects of BOB 06, primarily from flooding. [90] [91] [92] [93] [94] [95] The depression's influence brought extremely heavy rainfall across east and central India over a period of several days, dropping up to 23 cm (9.1 in) of precipitation over Bhograi on 20 August. Impacts were primarily felt in Odisha; rainfall led to landslides and flooding affecting at least 13 districts in Odisha, with 900 villages inundated and 170,000 people displaced by 22 August. [96] Losses from the 2022 Odisha Floods, which BOB 06 contributed to, totalled Rs1.26 billion (US$15.9 million). [97]

Early on 7 September, a low-pressure area formed over near the center of the Bay of Bengal under the influence of a cyclonic circulation. The low developed over the next several days under favourable conditions, eventually organizing into a depression over southern Odisha by 00:00 UTC on 11 September. The depression moved inland in a west-northwest direction, turning northwest early the next day. The depression subsequently lost organization, degenerating into a well-marked low pressure area over southern Chhattsigarh by 03:00 UTC on 12 September. [98]
The depression brought moderate to heavy rainfall to the states of Odisha, Chhattsigarh, and Telangana. No damages were reported from the effects of Land Depression 02. [98]

Sitrang originated from an area of low pressure near the Bay of Bengal offshore the Andaman and Nicobar Islands on 17 October, although it was designated as having a "low" chance for development at first. Later, during its existence, the Indian Meteorological Department designated a "high" possibility of the system becoming a depression. [99] Days later, warm waters and less wind shear contributed to favorable conditions for development, and the IMD classified the low pressure area as a depression, being called BOB 07, according to the third bulletin. The Joint Typhoon Warning Center issued a Tropical Cyclone Formation Alert (TCFA) on the system by 15:00 UTC of 22 October. [100] Hours later, BOB 07 gained momentum and in the agency's fifth bulletin, it was reported that it had intensified into a deep depression. [101] On 23 October, the cyclone gained more strength and reached the status of a cyclonic storm, being called Sitrang by the India Meteorological Department. By 09:00 UTC of 23 October, the JTWC designated the storm as Tropical Storm 05B. [102] As it was predicted to make landfall over Bangladesh, there was a prediction that Sitrang would turn into a severe cyclonic storm, but dry air hindered its intensification. [103] Upon making landfall near Patuakhali, Bangladesh, in the early hours of 24 October, the cyclone began to lose strength and was downgraded to a deep depression. The JTWC issued final warning on the system by 21:00 UTC of 24 October. [104] Afterwards, Sitrang continued to weaken, and in its thirteenth and final bulletin, the IMD declared that the cyclone was downgraded to a low pressure area by 06:00 UTC of 25 October. It dissipated over Northeast India that evening. [105]
Sitrang was the first cyclone to hit Bangladesh since Cyclone Mora in 2017. During its passage, at least 24 people died and another 8 are missing. [106] In Bangladesh, 700,000 people were evacuated from their homes because of heavy rains. [107] Damage was also recorded in eastern India. [108] At least 8 million customers lost power. [109] About 20 fishermen were rescued in the Bay of Bengal by the Indian Coast Guard. [110]

On 15 November, the IMD noted that a low-pressure area could form over the Bay of Bengal and develop into a depression over the next several days as it moved west-northwestwards. [111] By 17 November, a low-pressure area developed over the southeastern Bay of Bengal under the influence of a mid-level cyclonic circulation situated over the southern Andaman Sea. [112] Several days later, at 20:30 UTC (00:00 IST) on 19 November, the low organized into a depression about 600 km (370 mi) east of Jaffna, thus becoming BOB 08. [113] Soon after, the depression began tracking northwestward as it was subjected to moderate wind shear, [114] before turning into a west-northwestward direction again the next day. [115] At 03:00 UTC (06:30 IST) on 22 November, BOB 08 degenerated into a well-marked low pressure area as it succumbed to the influence of wind shear and dry air; [116] it then dissipated over northern Tamil Nadu on 24 November. [117]

The Indian Meteorological Department issued a bulletin stating that a tropical depression had formed in the Bay of Bengal and was designated BOB 09. [118] The JTWC, released a TCFA on the system, stating that it could intensify further, because of very warm waters and low to moderate wind shear, designating it Invest 96B. [119] A day later, both the JTWC and IMD classified this low pressure as a "cyclonic storm" and it was named Mandous. [120] [121] Mandous continued tracking westward, attaining wind speeds of 95 km/h (59 mph), thus strengthening into a Severe Cyclonic Storm. [122] [123] As it continued tracking westward, land interaction caused in to fall to Cyclonic Storm intensity. It later made landfall around Chennai, India as a Deep Depression. It fell to Depression intensity and later degenerated into a remnant low. [124]
In Chennai, about 200 trees were uprooted due to Cyclone Mandous. [125] Damage in Anantapur was Rs45 million (US$550 thousand). [126] Four people died Tamil Nadu from heavy rains. Five fishermen went missing off the coast of Sri Lanka due to the storm. [127] [128] Mandous caused nine deaths in total; four in Tamil Nadu and five in Sri Lanka. [129] [130]

On 14 December, the remnants of Cyclone Mandous regenerated into a depression in the Arabian Sea, and it was called ARB 03. [131] The Joint Typhoon Warning Center dubbed it as Invest 97A. Although forecasted to quickly degenerate into a remnant low, ARB 03 intensified into a Deep Depression, according to the Indian Meteorological Department, [132] and the JTWC dubbed it as Cyclone 07A. After reaching peak intensity, the Low-Level Circulation detached from the associated convection as dry air and wind shear increased, starting a weakening trend. It weakened into a low pressure area on 12:00 UTC of 17 December.

On 22 December, the JTWC began tracking a disturbance near Sumatra. It traveled westward before conducting an anticyclonic loop. It traveled north, then west, then north again. By this time, the IMD had already recognized it as a Depression, designating it as BOB 10, while the JTWC designated it as Invest 98B. The JTWC and the IMD assessed BOB 10 and gave it a low chance to develop into a tropical cyclone due to a broad LLC (Low Level Circulation) partially exposed to the southeast of flaring convection that is being sheared to the northwest, and marginally favorable environment. [133] On 25 December, the system weakened further as it approaches the coast of India being a remnant low. The JTWC was still tracking the system, and it made landfall in Northeastern Sri Lanka. The JTWC still gave it a low chance for tropical development, while the IMD said it couldn't develop further. [134] The storm continued to weaken and dissipated southwest of Sri Lanka on 27 December.
BOB 10 gave minor impacts to Sri Lanka.
Within this basin, a tropical cyclone is assigned a name when it is judged to have reached Cyclonic Storm intensity with winds of 65 km/h (40 mph). The names were selected by a new list from the Regional Specialized Meteorological Center in New Delhi by mid-year of 2020. There is no retirement of tropical cyclone names in this basin as the list of names is only scheduled to be used once before a new list of names is drawn up. Should a named tropical cyclone move into the basin from the Western Pacific, it will retain its original name. The names which were used for the 2022 season are listed below. [36]
This is a table of all storms in the 2022 North Indian Ocean cyclone season. It mentions all of the season's storms and their names, duration, peak intensities according to the IMD storm scale, damage, and death totals. Damage and death totals include the damage and deaths caused when that storm was a precursor wave or extratropical low. All of the damage figures are in 2022 USD.

In the Indian Ocean north of the equator, tropical cyclones can form throughout the year on either side of the Indian subcontinent, although most frequently between April and June, and between October and December.
Severe Cyclonic Storm Agni was a tropical cyclone of the 2004 North Indian Ocean cyclone season notable for its record proximity to the equator. It was the second North Indian Ocean cyclone to receive a name, after Onil earlier in the year. Agni formed on November 28 well to the southwest of India in the Arabian Sea, and steadily intensified as it tracked northwestward. The Joint Typhoon Warning Center (JTWC) estimated peak 1 minute sustained winds of 120 km/h (75 mph), while the India Meteorological Department (IMD) estimated peak 3 minute sustained winds of 100 km/h (60 mph); the IMD is the official warning center for the north Indian Ocean. After peaking, it weakened due to wind shear, dry air, and cooler waters, and the JTWC issued its final advisory on December 3 as it approached the coast of Somalia. The remnants of Agni moved along the Somalian coastline until dissipating on December 5.
The 2007 North Indian Ocean cyclone season was one of the most active North Indian Ocean cyclone seasons on record. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.
The 2009 North Indian Ocean cyclone season was an average season in terms of the number of cyclonic storms, however the storms were mostly weak in nature. It was the first season since 2005 wherein a storm did not strength above severe cyclonic storm status. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.
Cyclonic Storm Phyan developed as a tropical disturbance to the southwest of Colombo in Sri Lanka on November 4, 2009. Over the next couple of days, the disturbance gradually developed before weakening as it made landfall on Southern India on November 7. After the disturbance emerged into the Arabian Sea, it rapidly became more of a concern to the India Meteorological Department (IMD) reporting early on November 9 that the disturbance had intensified into a Depression, and designated it as Depression ARB 03 whilst the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert. Later that day, the JTWC designated the system as Cyclone 04A. During the next day, the Depression turned towards the northeast the IMD reported that it had intensified into a Cyclonic Storm and named it as Phyan.
The 2011 North Indian Ocean cyclone season was the least active tropical cyclone season in the North Indian Ocean since 1993. Only two cyclonic storms formed, below the average of four to six. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The scope of this article is limited to the Indian Ocean in the Northern Hemisphere, east of the Horn of Africa and west of the Malay Peninsula. There are two main seas in the North Indian Ocean — the Arabian Sea to the west of the Indian subcontinent, abbreviated ARB by the India Meteorological Department (IMD); and the Bay of Bengal to the east, abbreviated BOB by the IMD.
The 2012 North Indian Ocean cyclone season was a very inactive season. The season had a very late start, with the first system forming in October. During the season, only five systems formed, of which only two became cyclonic storms. Both the storms made landfall, and they, along with the deep depressions, were responsible for 128 deaths and economic losses worth at least $56.7 million.
The 2012 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. The scope of this article is limited to the Indian Ocean in the Northern Hemisphere, east of the Horn of Africa and west of the Malay Peninsula. There are two main seas in the North Indian Ocean — the Arabian Sea to the west of the Indian subcontinent, abbreviated ARB by the India Meteorological Department (IMD); and the Bay of Bengal to the east, abbreviated BOB by the IMD. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center releases unofficial advisories. This timeline includes information that was operationally released, meaning that data from post-storm reviews by the IMD, such as a storm that was not operationally warned upon, has not been included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, and dissipations during the season.
The 2014 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. The season included two very severe cyclonic storms, both in October, and one other named cyclonic storm, classified according to the tropical cyclone intensity scale of the India Meteorological Department. Cyclone Hudhud is estimated to have caused US$3.58 billion in damage across eastern India, and more than 120 deaths.
The 2015 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. It was an average season with 4 cyclonic storms. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between months of April and December, with the peak from May to November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.
The 2016 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. It was the deadliest season since 2010, killing more than 400 people. The season was an average one, seeing four named storms, with one further intensifying into a very severe cyclonic storm. The first named storm, Roanu, developed on 19 May while the season's last named storm, Vardah, dissipated on 18 December. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with the two peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.
The 2020 North Indian Ocean cyclone season was the costliest North Indian Ocean cyclone season on record, mostly due to the devastating Cyclone Amphan. it was an above average season featuring 5 cyclonic storms. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and November, with peaks in late April to May and October to November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The season began on May 16 with the designation of Depression BOB 01 in the Bay of Bengal, which later became Amphan. Cyclone Amphan was the strongest storm in the Bay of Bengal in 21 years and would break Nargis of 2008's record as the costliest storm in the North Indian Ocean. The season concluded with the dissipation of Cyclone Burevi on December 5. Overall, the season was slightly above average, seeing the development of five cyclonic storms.
The 2021 North Indian Ocean cyclone season was an average season, the North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, peaking between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The season began on April 2, when a depression designated as BOB 01 was formed in the north Andaman Sea and quickly made landfall in Myanmar. The basin remained quiet for over a month before Cyclone Tauktae formed. It rapidly intensified into an extremely severe cyclonic storm before making landfall in Gujarat, become the strongest storm ever to strike that state since the 1998 Gujarat cyclone. Later that month, BOB 02 formed and later strengthened into Cyclone Yaas. Yaas rapidly intensified into a very severe cyclonic storm before making landfall in northwestern Odisha. The season's strongest tropical cyclone was Cyclone Tauktae, with maximum wind speeds of 185 km/h (115 mph) and a minimum barometric pressure of 950 hPa (28.05 inHg).
Cyclonic Storm Gulab and Severe Cyclonic Storm Shaheen were two tropical cyclones that caused considerable damage to South and West Asia during the 2021 North Indian Ocean cyclone season. Gulab impacted India and Pakistan, while Shaheen impacted Iran, Oman and the United Arab Emirates. Gulab was the third named storm of the 2021 North Indian Ocean cyclone season, as well as the fourth named storm of the season after its reformation in the Arabian Sea as Shaheen. The cyclone's origins can be traced back to a low-pressure area situated over the Bay of Bengal on September 24. The Indian Meteorological Department (IMD) named this new cyclone Gulab. On September 26, Gulab made landfall in India's Andhra Pradesh and Pakistans Karachi but weakened overland, before degenerating into a remnant low on September 28. The system continued moving westward, emerging into the Arabian Sea on September 29, before regenerating into a depression early on September 30. Early on October 1, the system restrengthened into a Cyclonic Storm, which was named Shaheen. The system gradually strengthened as it entered the Gulf of Oman. While slowly moving westward, the storm turned southwestward, subsequently making an extremely rare landfall in Oman on October 3, as a Category 1-equivalent cyclone. Shaheen then rapidly weakened, before dissipating the next day.
The 2021 South India floods are a series of floods associated with Depression BOB 05 and a low pressure system that caused widespread disruption across the Indian states of Tamil Nadu, Andhra Pradesh, and the nearby Sri Lanka. The rainfall started on 1 November in Tamil Nadu. The flooding was caused by extremely heavy downpours from BOB 05, killing at least 41 people across India and Sri Lanka.
Cyclonic Storm Jawad was a relatively very weak tropical cyclone that caused disruptions over the East India and Bangladesh while bringing heavy rainfall and strong winds over these states as a weakened system. The tenth depression, sixth deep depression and fifth cyclonic storm of the active 2021 North Indian Ocean cyclone season, its predecessor was first tracked by Joint Typhoon Warning Center (JTWC) in the South China Sea as an area of low pressure. It then moved west-northwestwards into the Gulf of Thailand, where it crossed into the Andaman Sea by December 1. Near midnight of that day, the JTWC issued a TCFA on the system and on the next day, the India Meteorological Department (IMD) upgraded the system to a depression after passing through the Nicobar Islands. Further intensification ensued as the depression tracked through environmental conditions favorable for strengthening, and the system was upgraded into a deep depression on December 3 and into a cyclonic storm by 06:00 UTC that day, with the IMD naming it Jawad. However, this intensification was short-lived, as the system weakened to a deep depression back due to wind shear.
The 2023 North Indian Ocean cyclone season was an above-average and deadly season, becoming the most active since 2019, with nine depressions and six cyclonic storms forming. It was the deadliest since 2017, mostly due to Cyclone Mocha, and had the second-highest accumulated cyclone energy (ACE) in the basin, after 2019. It also had the most extremely severe cyclonic storms on record, tying with 1999 and 2019. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with the peak from May to November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. However, a cyclone can form at any time during the year shown by an unnamed depression that affected Sri Lanka in January–February.
Severe Cyclonic Storm Asani was a strong tropical cyclone that made landfall in India in May 2022. It was the strongest storm of 2022 North Indian Ocean cyclone season. The third depression and deep depression, and the first named storm of the 2022 North Indian Ocean cyclone season, Asani originated from a depression that the Indian Meteorological Department first monitored on May 7. Conditions rapidly favored development as the system became a deep depression by that day before intensifying to a Cyclonic Storm Asani. On the next day it further intensified and peak to a severe cyclonic storm, before making landfall as a deep depression system over Andhra Pradesh. It degenerated into a well marked low-pressure on May 12.
Severe Cyclonic Storm Mandous was the third cyclonic storm, as well as the third most intense tropical cyclone of the 2022 North Indian Ocean cyclone season. The remnants of the system later regenerated into Deep Depression ARB 03 in the Arabian Sea. The system struck the Andaman and Nicobar Islands, as well as South India.
The 2024 North Indian Ocean cyclone season is an ongoing event in the annual cycle of tropical cyclone formation. It has been unreasonably less active in terms of formation of cyclonic storms. The season has no official bounds, but cyclones tend to form between April and December, with the peak from May to Early November. These dates conventionally delimit each year when most tropical cyclones form in the northern Indian Ocean.
