Typhoon Gaemi,known in the Philippines as Super Typhoon Carina,was a powerful and destructive tropical cyclone which impacted East China,Taiwan,and the Philippines in late July 2024. Gaemi,which means ant in Korean,the third named storm and second typhoon of the annual typhoon season,formed as a tropical depression east of Palau on July 19. Owing to favorable environmental conditions,the typhoon intensified and reached its peak with ten-minute maximum sustained winds of 165 km/h (105 mph),and a central atmospheric pressure of 940 hPa (27.76 inHg). With one-minute sustained winds at 230 km/h (145 mph),Gaemi was classified as a Category 4-equivalent typhoon. The storm then turned north-northwestward,along the western periphery of a subtropical ridge. After stalling and executing a tight counter-clockwise loop near the coast,Gaemi slightly weakened due to land interaction before making landfall on the northeastern coast of Taiwan on July 24. It emerged over the Taiwan Strait just six hours after landfall. Gaemi made landfall in China as a minimal tropical storm in the Xiuyu District of Putian in Fujian Province. Once inland,the system weakened to a tropical depression by July 27.
Together with the southwest monsoon and Tropical Storm Prapiroon,heavy rains were reported over southern and northern Luzon,triggering widespread flash floods in various areas of the region. The monsoon enhanced by Gaemi's impact on Luzon led to comparisons to 2009's Typhoon Ketsana. The oil tanker MT Terra Nova,carrying around 1.5 million liters of industrial fuel,capsized and sank in 34 m (112 ft) depth of water in Manila Bay off the coast of Limay,Bataan. In Japan,the island of Yonaguni recorded wind speeds of up to 180 km/h (110 mph). In Indonesia,large waves of up to 2.5 m (8.2 ft) in height affected the Molucca Sea,North Natuna Sea,Natuna Sea,and the areas between the Sitaro Islands and Bitung,and between the Sangihe Islands and Talaud Islands. A maximum rainfall accumulation of 512.8 mm (20.19 in) was observed in Luoyuan County in Fujian Province. The remnants of Gaemi also hit North Korea,where a government official,as reported by TV Chosun,indicated that the floods might have caused between 1,000—1,500 deaths or disappearances. Nevertheless,North Korean state media had not mentioned any casualties. In all,the typhoon killed at least 126 people,injured 929 others,and caused US$253 million worth of damage.
The origins of Typhoon Gaemi can be traced back to July 17, when the Japan Meteorological Agency (JMA) reported that a low-pressure area had formed east of Palau. [1] Environment was generally favourable for tropical cyclogenesis, with warm sea surface temperatures of 27–28 °C (81–82 °F), low vertical wind shear and excellent poleward and equatorward outflow. Satellite imagery indicated that formative convective banding had begun to wrap into the centre of circulation. [2] After slowly consolidating for two days, the Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert for the system on July 19, due to its rapidly consolidating broad low-level circulation center. [3] Shortly after, both the JMA and the JTWC followed suit and upgraded the tropical depression, with the latter designating the system as 05W. [4] [5] The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) followed suit a few hours later, upgrading the system from a low-pressure area to a depression and assigning it the name Carina. [6] Early the following day, the depression strengthened into a tropical storm and was named Gaemi by the JMA. [7]
Gaemi's deep convection later began to consolidate into a small central dense overcast, with cloud tops reaching temperatures of −90 °C (−130 °F). [8] It then intensified into a severe tropical storm due to being in a conducive environment for development on July 21. [9] The storm displayed convective banding features around its western periphery, wrapping into a low-level center of circulation. [10] Around 00:00 UTC on July 22, the JMA then reported that Gaemi had intensified into a typhoon due to good upper-level outflow, warm sea surface temperatures, and high ocean heat content. [11] Gaemi then turned north-northwestward, along the western periphery of a subtropical ridge. [12] As it remained quasi-stationary six hours later, due to a weak steering environment between the subtropical ridge to the northwest and east, the JTWC upgraded Gaemi to minimal typhoon-equivalent status around 21:00 UTC that day. [13] After undergoing an eyewall replacement cycle and developing a pinhole eye, Gaemi rapidly intensified and peaked at Category 4-equivalent intensity on the Saffir-Simpson scale at 21:00 UTC on 23 July, with 1-minute sustained winds of 230 km/h (145 mph). [14] The JMA reported that Gaemi reached its peak intensity at 06:00 UTC that day with 10-minute sustained winds of 165 km/h (105 mph) and a central pressure of 940 hPa (27.76 inHg). [15] After stalling and executing a tight counter-clockwise loop near the coast, [16] Gaemi slightly weakened into a below-equivalent typhoon status due to land interaction before it made landfall on the northeastern coast of Taiwan on July 24. [17] Gaemi accelerated as it moved across the island and emerged into the Taiwan Strait just six hours after making landfall. [18] The system quickly weakened to a minimal tropical storm as it made its closest approach offshore of eastern China. [19] Soon after, [20] the JTWC ceased issuing advisories on the system as it made its final landfall at Xiuyu, Putian in Fujian Province. [21] Once inland, the JMA continued tracking Gaemi until it weakened into a tropical depression on July 27. [22]
As Gaemi developed in the Philippine Area of Responsibility, the PAGASA began issuing weather advisories on the system, as it interacted with the southwest Tropical Storm Prapiroon over the South China Sea. [23] Initial forecasts issued by the agency projected that Gaemi would not make landfall on the Philippines, however, moisture from the storm would be drawn into the southwest monsoon and bring heavy rainfall and strong winds to the archipelago. [24] Therefore, on July 22, the PAGASA issued a Signal No. 1 wind warning in parts of the Babuyan Islands, Batanes, Cagayan, and Isabela. The PAGASA expected winds of up to 61 km/h (69 mph) in these provinces. [25] On the morning of July 23, PAGASA raised to Signal No. 2 warning in Batanes as Gaemi's outer rainbands began to affect the province. [26] Classes in all levels and several local government units were suspended in some areas of Luzon including Metro Manila on July 23 due to the storm. [27] [28] Several commercial flights were cancelled at Ninoy Aquino International Airport, as well as flights in Basco, Cagayan, and Tuguegarao. Ship travel was suspended in Itbayat. [29] The Provincial Disaster Risk Reduction and Management Office (PDRRMO) in La Union raised a red alert on July 21, requiring all personnel to be readied for deployment. Emergency staff were deployed to operations centers where stockpiles of supplies and vehicles were prepared. Government offices in the province closed on the afternoon of July 23, with only emergency staff remaining. Immuki Island was isolated as a result of suspended sailing. Beaches in San Juan were closed to visitors, as well as Tangadan Falls in San Gabriel. [30]
On July 21, the government of Iloilo City began a preemptive evacuation. Documentation began to prepare funding of ₱10,000 (US$171) to occupants of destroyed dwellings and ₱7,000 (US$120) to those of partially destroyed dwellings. [31] In the Cordillera Administrative Region, ₱73.6 million (US$1.2 million) worth of family food packages, totaling 25,357, were propositioned at multiple warehouses. In addition, approximately ₱52.7 million (US$899,000) worth of non-food supplies were gathered at these warehouses. [32] The PDRRMO office in Pangasinan issued a red emergency alert, allocating 64,564 packages of supplies, as well as a standby fund of ₱86.75 million (US$1.48 million). [33] The Department of Social Welfare and Development (DSWD) prepared their stock fund of ₱2.5 billion (US$42.8 million) for assistance during the typhoon. A total of 129,735 family food packages were positioned at warehouses and resource centers in Pasay, 93,516 packages were positioned in Mandaue, and 442,125 packages were made available at DSWD Offices No. 3, 5, and 6. The Philippine Air Force readied three Tactical Operations Group for response to the typhoon, including water rescue crews and helicopters for search and rescue and to serve as air ambulances. Rapid response teams trained for recovery efforts and damage assessments were also readied in Clark, Davao City, Laoag, Mactan, and the Zamboanga Peninsula. [34]
The Central Weather Administration issued numerous typhoon and torrential rain warnings in anticipation of Gaemi. Ferry services were suspended, [35] and the annual Han Kuang military exercises were cancelled. Domestic flights from the airlines Mandarin Airlines and Daily Air were also cancelled, alongside 201 international flights. [36] [37] Cancelled sea and air travel stranded around 10,000 visitors in Penghu. [38] The Taiwan Stock Exchange ceased operations in preparation for the typhoon. The Taiwan Semiconductor Manufacturing Company, a major computer chip manufacturer for brands such as Apple Inc. and Nvidia planned to continue normal operations amidst the storm, however, an emergency response team was placed on standby. [39] The government of Taiwan placed 29,000 military personnel on standby for recovery efforts. Over 2,000 residents of mountainous areas on the island were evacuated. [37] Evacuations also took place in Heping District, Taichung; 385 residents were evacuated from nine flood-prone districts of Tainan. [38] Overall, a total of 8,569 people had evacuated to shelters prior to the typhoon's impact. [40]
The Highway Bureau closed the Central Cross-Island Highway between Guanyuan and Taroko and the Suhua Highway between Chongde and Suao. [41] The Forestry and Nature Conservation Agency closed ten recreational areas due to safety concerns. Yushan National Park banned hiking activities and forced 45 hiking groups to descend from mountains in the park. The Yilan International Children's Folklore and Folkgame Festival and Dongshih Summer Festival were halted due to the typhoon. [42] The Wenhu Line of the Taipei Metro, connecting Neihu District and Wenshan District, shut down on the afternoon of July 24. All other metro lines remained in operation. [43] Schools and government offices were closed nationwide on July 25. [44]
The Japan Meteorological Agency said that rainfall on 25 July could reach 8 in (200 mm) in the Yaeyama Islands, 5.9 in (150 mm) on Okinawa Island and nearby areas, and 4 in (100 mm) in Miyako-jima within a 24-hour period. [45] Authorities in Okinawa Prefecture warned residents of the Sakishima Islands to remain indoors and for boats to not leave port. [46] Japan Airlines and All Nippon Airways cancelled 100 flights in and out of Ishigaki, Miyako-jima, and Naha. [47]

Combined with moisture from the southwest monsoon, the influence of Gaemi produced heavy rainfall across parts of the Philippines. Heavy rainfall occurred in Albay, Aklan, Antique, Bataan, Batangas, Cavite, Capiz, Oriental Mindoro, Rizal, and Zambales. Residents of Romblon received flood warnings and a yellow warning for heavy rainfall. Two thoroughfares in the Zamboanga Peninsula and Cordillera Administrative Region, respectively, were blocked due to rockfalls, with access only possible to small vehicles. [61] The Angat Dam saw water level increases of up to 3.8 m (12 ft) amidst rainfall from Gaemi. [62] Downstream, the reservoir of La Mesa Dam in Quezon City also rose up causing water to overflow. [63] On July 24, the third and highest alarm was raised on the Marikina River after it rose to 18.4 m (60 ft) before peaking at 20.7 m (68 ft), prompting evacuations. [64] Strong water currents along the river also caused several barges to collide into the F. Manalo Bridge in Pasig. [65] In Taguig, floodwaters reached waist-level. [66] Houses in coastal villages of Orani, Bataan were inundated by floodwaters. Homes were also inundated by floodwaters in Samal, where rice and other crops received partial losses due to the flooding. Soil erosion occurred in Baguio, damaging a riprap. Strong winds impacted Olongapo, toppling electrical poles. [29] A downed tree also blocked traffic in Quezon City. [67] Several sections of the North Luzon Expressway were rendered impassable due to the torrential rain brought by the two weather conditions. [68] Highways connecting Nueva Vizcaya with Benguet and Pangasinan were blocked by landslides, [69] with 34 houses in Kayapa also damaged. [70] Severe weather conditions forced vessels to remain in ports, stranding 70 people in Southern Tagalog and Bicol Region, combined. An additional 48 passengers were stranded in Pasacao, Camarines Sur. [62]
At least 40 fatalities [53] and three missing persons were reported in the Philippines, [50] along with 17 injuries [71] as a result of Gaemi, combined with the effects of the southwest monsoon and nearby Severe Tropical Storm Prapiroon. [72] [73] Across the Caraga, Mimaropa, Western Visayas, and Zamboanga Peninsula regions, Gaemi resulted in agricultural losses totaling ₱79 million (US$1.35 million). [48] Agricultural damage in Pampanga reached ₱266 million (US$4.56 million). Calabarzon reported of an estimated damage of ₱29.1 million (US$495,864) to their irrigation systems and ₱111.81 million ($1.91 million) to its agricultural losses. [74] [49] A total of 224 families were affected by the storm across Bataan, Camarines Sur, Iloilo City, Masbate, and Pampanga. [67] A state of calamity was declared in Metro Manila and in the provinces of Bataan, Batangas, Bulacan, Cavite, Ilocos Norte, Oriental Mindoro and Pampanga [75] [76] [77] due to the widespread floods that occurred in various areas of the region. [78] The monsoon enhanced by Gaemi's impact on Luzon led to comparisons to 2009's Typhoon Ketsana, which was known locally as Tropical Storm Ondoy. [79] [80] [81] A total of 1,215 schools were forced to postpone the start of the school year on July 29 due to damage or conversion into evacuation shelters. [82] [83]
The oil tanker MT Terra Nova, carrying around 1.5 million liters of industrial fuel, capsized and sank in 34 m (112 ft) depth of water [84] in Manila Bay off the coast of Limay, Bataan, causing an oil spill with a length of four kilometers. [85]
Gaemi killed 10 people in Taiwan as it approached the island; [86] a woman killed by a falling tree in Kaohsiung, and another death caused by a falling excavator in Sanxia District, New Taipei. [57] Additionally, a woman was killed and her son was critically injured after a wall collapsed and struck their car in Hualien City, [87] three more died in Chiayi County, [88] an elderly man was killed by a landslide in Cishan District, [89] another was killed in a related car accident in Yunlin County, [90] and one more death occurred in Tainan. [91] While docked in southern Taiwan, the freighter Fu Shun capsized, [85] killing the ship's captain. [92] Across the island, 902 people were injured, two others were missing and 262,000 were left without power. [55] [38] [93] Up to 1,204.5 mm (47.4 in) of rainfall was observed in the Maolin District of Kaohsiung. [94] A total of 1,232 people were displaced by the typhoon and were placed into 279 emergency camps. [95] The Ministry of Agriculture calculated that the industry sustained approximately NT$1.7 billion in damages due to Gaemi. [96]
Gaemi made landfall in China as a tropical storm with maximum sustained winds of around 120 km/h (75 mph) in the Xiuyu District of Putian in Fujian Province. There were 49 deaths confirmed in the country, 48 of them in Hunan Province, where 35 others were missing; [58] 15 people were killed, 21 were missing and six more were injured after a mudslide struck a homestay in Hengyang, Hunan. Additionally, a delivery driver was killed by a falling tree in Shanghai. [97] About 1,000 homes were damaged and 1,345 road collapses were reported in Zixing, [98] where 30 people died. [58]
Heavy rainfall occurred in more than ten provinces and cities, including the cities of Fuzhou, Shenyang, Wuzhou, and Zhengzhou. [99] A maximum rainfall accumulation of 512.8 mm (20.19 in) was observed in Luoyuan County in Fujian. [100] Precipitation was reported in over 72 townships in Fujian. [101] Across Fujian, a total of 85 hectares (210 acres) of crops were damaged, with losses totaling ¥11.5 million (US$1.6 million). [59] Approximately 628,000 people were affected by the typhoon in Fujian, 290,000 of which were evacuated. [102]
Gaemi's remnants also hit North Korea, [98] resulting in heavy flooding in North Pyongan Province which stranded 5,000 people. [103] According to TV Chosun, a south Korean government official reported that between 1,000 and 1,500 people could have been killed or left missing due to the floods. However, North Korean state media said there were casualties but did not provide figures. [104] In the city of Sinuiju and the neighboring Uiju County, about 4,100 houses, 3,000 hectares (7,410 acres) of agricultural fields and numerous public buildings, roads and railways were flooded. [105] North Korean media covered the disasters much more prominently compared to previous disasters or incidents, with North Korea's state newspaper calling it a "grave crisis", as well as television showing footage of flooded areas. [106] North Korean state media reported that Supreme Leader Kim Jong-un traveled to flooding sites to survey damages. [107] State media stated that he "personally directed the battle" towards rescuing civilians, and declared sections of three provinces as disaster zones. [108]
A government meeting agreed on constructing 4,400 new houses in Sinuiju and Uiju, while also reinforcing embankments and restoring damaged infrastructure in Jagang province. [109] South Korea offered to give humanitarian aid to North Korea following the downpours, which the DPRK indicated that it would reject it. [107] Russian President Vladimir Putin expressed condolences to North Korea for damage caused by the flooding, and offered to provide humanitarian support. [107]
In Japan, the island of Yonaguni recorded wind speeds of up to 180 km/h (110 mph) on July 24. [45] In Indonesia, the Meteorology, Climatology, and Geophysical Agency warned of heavy rainfall in North Kalimantan, East Kalimantan, Central Sulawesi, North Maluku, and Maluku, due to the influence of Gaemi. Large waves of up to 2.5 m (8.2 ft) in height affected the Molucca Sea, North Natuna Sea, Natuna Sea, and the areas between the Sitaro Islands and Bitung, and between the Sangihe Islands and Talaud Islands. [110] In Vietnam, the storm damaged 90 houses in Ben Tre. [111] Flash floods and landslides in many places after the storm's aftermath also killed 18 people. [60]
The 2012 Pacific typhoon season was a slightly above average season that produced 25 named storms, fourteen typhoons, and four intense typhoons. It was a destructive and the second consecutive year to be the deadliest season, primarily due to Typhoon Bopha which killed 1,901 people in the Philippines. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season ran throughout 2012, though most tropical cyclones typically develop between May and October. The season's first named storm, Pakhar, developed on March 28, while the season's last named storm, Wukong, dissipated on December 29. The season's first typhoon, Guchol, reached typhoon status on June 15, and became the first super typhoon of the year on June 17.
Severe Tropical Storm Meari, known in the Philippines as Severe Tropical Storm Falcon, was an unusually large tropical cyclone that caused significant damage from the Philippines to the Korean Peninsula in June 2011.
The 2013 Pacific typhoon season was the most active Pacific typhoon season since 2004, and the deadliest since 1975. It featured Typhoon Haiyan, one of the most powerful storms and one of the strongest landfalling tropical cyclones in history. It was an above-average season with 31 named storms, 13 typhoons, and five super typhoons. The season's first named storm, Sonamu, developed on January 4 while the season's last named storm, Podul, dissipated on November 15. Despite the activity, most of the first seventeen named storms before mid-September were relatively weak, as only two of them reached typhoon intensity. Total damage amounted to at least $26.41 billion (USD), making it at the time the costliest Pacific typhoon season on record; it is currently the fourth costliest, behind the 2018, 2019 and 2023 seasons.
The 2015 Pacific typhoon season was a slightly above average season that produced twenty-seven tropical storms, eighteen typhoons, and nine super typhoons. The season ran throughout 2015, though most tropical cyclones typically develop between May and November. The season's first named storm, Mekkhala, developed on January 15, while the season's last named storm, Melor, dissipated on December 17. The season saw at least one named tropical system forming in each of every month, the first time since 1965. Similar to the previous season, this season saw a high number of super typhoons. Accumulated cyclone energy (ACE) during 2015 was extremely high, the third highest since 1970, and the 2015 ACE has been attributed in part to anthropogenic warming, and also the 2014-16 El Niño event, that led to similarly high ACE values in the East Pacific.
The 2016 Pacific typhoon season is considered to have been the fourth-latest start for a Pacific typhoon season since reliable records began. It was an average season, with a total of 26 named storms, 13 typhoons, and six super typhoons. The season ran throughout 2016, though typically most tropical cyclones develop between May and October. The season's first named storm, Nepartak, developed on July 3, while the season's last named storm, Nock-ten, dissipated on December 28.
The 2018 Pacific typhoon season was at the time, the costliest Pacific typhoon season on record, until the record was beaten by the following year. The season was well above-average, producing twenty-nine storms, thirteen typhoons, seven super typhoons and six Category 5 tropical cyclones. The season ran throughout 2018, though most tropical cyclones typically develop between May and October. The season's first named storm, Bolaven, developed on January 3, while the season's last named storm, Man-yi, dissipated on November 28. The season's first typhoon, Jelawat, reached typhoon status on March 29, and became the first super typhoon of the year on the next day.
Typhoon Guchol, known in the Philippines as Super Typhoon Butchoy, was a powerful tropical cyclone which became the first typhoon to make landfall in Japan on June since 2004. The storm formed as tropical disturbance south-southeast of Pohnpei on June 7, and was upgraded to a tropical depression on June 10. The system later intensified in favorable conditions, and reached typhoon intensity on June 15. It reached peak intensity late on June 17, before making landfall over Japan as a typhoon on June 19. The system became extratropical shortly after traversing Japan and was last noted by the Japan Meteorological Agency on June 22.
Typhoon Tembin, known in the Philippines as Typhoon Igme, was an intense tropical cyclone in the Western Pacific Ocean that had an unusual trajectory, approaching Taiwan twice. Tembin, which means balancing scale or Libra in Japanese, was the eighth typhoon and the fourteenth named storm of the 2012 Pacific typhoon season. After making landfall over the southern tip of Taiwan late on August 23, Tembin weakened but regained strength in the South China Sea, looping before making a second landfall on southern Taiwan as a tropical storm on August 27; however, the system did not restrengthen in the East China Sea, and made landfall over South Korea on August 30 before becoming extratropical.
Typhoon Sanba, known in the Philippines as Super Typhoon Karen, was the strongest tropical cyclone worldwide in 2012. The sixteenth named storm and tenth typhoon of the annual typhoon season, Sanba formed as a tropical depression east of the Philippines on September 10. The storm gradually intensified as it moved generally northward in an area favorable for tropical development. The system was soon upgraded to a tropical storm less than a day after formation and subsequently further to a typhoon on September 12. Later that day, Sanba entered a phase of rapid intensification, and quickly strengthened. On September 13, the system attained its peak intensity with maximum sustained winds of 125 mph (205 km/h), and a barometric pressure of 900 mbar, becoming the strongest typhoon in the Western Pacific Ocean since Megi in 2010. Accelerating towards more northerly latitudes, a period of gradual weakening ensued afterwards as its eye expanded. It made landfall on South Korea late on September 17 as a typhoon before transitioning into an extratropical cyclone the following day. Sanba's remnants tracked into the Primorsky Krai region of eastern Russia before they were last noted on September 19.
The 2020 Pacific typhoon season was the first of an ongoing series of below average Pacific typhoon seasons, and became the first with below-average tropical cyclone activity since 2014, with 23 named storms, 10 of which became typhoons and only 2 became super typhoons. This low activity was a consequence of La Niña that persisted from the summer of the year. It had the sixth-latest start in the basin on record, slightly behind 1973, and was the first to start that late since 2016. The first half of the season was unusually inactive, with only four systems, two named storms and one typhoon at the end of July. Additionally, the JTWC recorded no tropical cyclone development in the month of July, the first such occurrence since reliable records began. The season's first named tropical cyclone, Vongfong, developed on May 8, while the season's last named tropical cyclone, Krovanh, dissipated on December 24. However, the season's last system was an unnamed tropical depression which dissipated on December 29.
This timeline documents all of the events of the 2012 Pacific typhoon season. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. During the season, 34 systems were designated as tropical depressions by either the Japan Meteorological Agency (JMA), the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the Joint Typhoon Warning Center (JTWC), or other National Meteorological and Hydrological Services such as the China Meteorological Administration and the Hong Kong Observatory. Since the JMA runs the Regional Specialized Meteorological Centre (RSMC) for the Western Pacific, they assigned names to tropical depressions which developed into tropical storms in the basin. PAGASA also assigned local names to systems which are active in their area of responsibility; however, these names are not in common use outside of the Philippines.
Typhoon Matmo, known in the Philippines as Typhoon Henry, was the first tropical cyclone to impact Taiwan in 2014. It was the tenth named storm and the fourth typhoon of the 2014 Pacific typhoon season. The typhoon is believed to be one of the main reasons behind the crash of TransAsia Airways Flight 222, which occurred a day after it made landfall. There were fifty-four passengers on board and a crew of four, of whom 48 were killed. Taiwan News reported that "first suspicions hinted" the accident might be related to Matmo. The typhoon developed from a cluster of thundershowers consolidating around an area of low pressure in the doldrums. It initially followed a westward track, then made a sharp northwest turn before making landfall on Taiwan, and then China. After moving further inland, Matmo slowly curved back northeastwards and became extratropical before its remnants affected the Korean Peninsula.
Typhoon Noul, known in the Philippines as Super Typhoon Dodong, was a relatively small but powerful tropical cyclone that affected several areas but caused minor damage. The sixth named storm and third typhoon of the annual typhoon season, Noul formed as a tropical depression over the eastern Caroline Islands on May 2, 2015. It moved generally to the west and west-northwest, gradually intensifying into a tropical storm and later typhoon. On May 9, Noul began rapid deepening as it developed a well-defined eye. Early the next day, the Japan Meteorological Agency (JMA) estimated peak 10 minute sustained winds of 205 km/h (125 mph), while the American-based Joint Typhoon Warning Center (JTWC) estimated peak 1 minute winds of 260 km/h (160 mph), equivalent to Category 5 on the Saffir–Simpson hurricane wind scale. Noul struck northeastern Luzon in the Philippines at that intensity and greatly weakened. After passing east of Taiwan, the typhoon accelerated to the northeast and weakened due to unfavorable conditions. On May 12, Noul became extratropical south of Japan, and the remnants continued to the northeast for several days, dissipating on May 16.
Typhoon Chan-hom, known in the Philippines as Typhoon Falcon, was a large, powerful and long-lived tropical cyclone that affected most countries in the western Pacific basin. The ninth named storm of the 2015 Pacific typhoon season, Chan-hom developed on June 29 from a westerly wind burst that also spawned Tropical Cyclone Raquel in the southern hemisphere. Chan-hom slowly developed while moving to the northwest, aided by warm waters but disrupted by wind shear. The storm meandered near the Northern Marianas Islands, passing over the island of Rota before beginning a steady northwest track. While near the island, the storm dropped heavy rainfall on neighboring Guam, causing flooding and minor power outages. Chan-hom intensified into a typhoon on July 7, and two days later passed between the Japanese islands of Okinawa and Miyako-jima. There, strong winds left 42,000 people without power, while 27 people were injured. Around that time, the storm caused a surge in the monsoon trough, in conjunction with Tropical Storm Linfa, which caused flooding and killed 16 people in the Philippines.
Typhoon Goni, known in the Philippines as Typhoon Ineng, was a powerful tropical cyclone that affected much of East Asia in late August 2015. Developing in tandem with Typhoon Atsani to its east, Goni formed on August 13, and passed through the Mariana Islands two days later. By that time, radar imagery showed a formative eye, signaling an rapidly intensifying storm. Goni evolved into an intense typhoon in the Philippine Sea before weakening and stalling north of Luzon. The typhoon re-intensified and attained peak winds of 185 km/h (115 mph) on August 23 while moving through the southern Ryukyu Islands. Goni weakened slightly and moved across the Japanese island of Kyushu. The tropical cyclone transitioned into an extratropical cyclone in the Sea of Japan on August 25, crossed into eastern Russia and China a day later, and dissipated on August 30.
Typhoon Meranti, known in the Philippines as Super Typhoon Ferdie, was one of the most intense tropical cyclones on record. Impacting the Batanes in the Philippines, Taiwan, as well as Fujian Province in September 2016, Meranti formed as a tropical depression on September 8 near the island of Guam. Tracking to the west northwest, Meranti gradually intensified until September 11, at which point it began a period of rapid intensification. Continuing to rapidly intensify, it became a super typhoon early on September 12, as it passed through the Luzon Strait, ultimately reaching its peak intensity on September 13 with 1-minute sustained winds of 315 km/h (195 mph). Shortly afterwards, it passed directly over the island of Itbayat. Meranti passed to the south of Taiwan as a super typhoon, and began weakening steadily as a result of land interaction. By September 15, it struck Fujian Province as a Category 2-equivalent typhoon, becoming the strongest typhoon on record to impact the province. Upon moving inland, rapid weakening ensued and Meranti became extratropical the next day, dissipating shortly afterwards after it passed to the south of the Korean Peninsula.
Severe Tropical Storm Nanmadol, known in the Philippines as Severe Tropical Storm Emong, was a tropical cyclone that impacted southern Japan during July 2017. Nanmadol developed over in the Philippine Sea as a tropical depression on July 1, and strengthened into the third named storm of the 2017 typhoon season on July 3. After gaining organization, the system rapidly developed and intensified into a severe tropical storm and reached its peak intensity with a 10-minute maximum sustained winds of 100 km/h (62 mph) and a minimum barometric pressure of 985 hPa (29.1 inHg). On July 4, Nanmadol turned eastwards and made landfall near Nagasaki, Kyushu, just before it transitioned into an extratropical cyclone.
The 2023 Pacific typhoon season was the fourth consecutive below-average season and became the third-most inactive typhoon season on record in terms of named storms, with just 17 named storms developing, only ahead of 2010 and 1998. Despite the season occurring during an El Niño event, which typically favors activity in the basin, activity was abnormally low. This was primarily due to a consistent period of negative PDO, which typically discourages tropical storm formation in this basin. The season was less active than the 2023 Atlantic hurricane season in terms of named storms, the fourth such season on record, after 2005, 2010 and 2020; and the first during an El Niño event. The season's number of storms also did not exceed that of the 2023 Pacific hurricane season. Only ten became typhoons, with four strengthening further into super typhoons. However, it was very destructive, primarily due to Typhoon Doksuri which devastated the northern Philippines, Taiwan, and China in July, becoming the costliest typhoon on record as well as the costliest typhoon to hit mainland China, and Typhoon Haikui in September, which devastated China, Taiwan, and Hong Kong. The season was less active in Southeast Asia, with no tropical storm making landfall in mainland Vietnam.
The 2024 Pacific typhoon season is an ongoing event in the annual cycle of tropical cyclone formation in the western Pacific Ocean. It is the fifth-latest starting Pacific typhoon season on record. The season runs throughout 2024, though most tropical cyclones typically develop between May and October. The season's first named storm, Ewiniar, developed on May 25, and eventually intensified into the first typhoon of the season.
Severe Tropical Storm Prapiroon, known in the Philippines as Tropical Depression Butchoy was a compact tropical cyclone that made landfall in Hainan and Vietnam in July 2024. The fourth named storm of the 2024 Pacific typhoon season. Prapiroon was first identified as an area of persistent convection southeast of Manila, Philippines. It then drifted northward over the South China Sea, strengthening into a severe tropical storm on July 22. The storm's eye became visible on microwave satellite imagery before making landfall in Wanning, Hainan. It soon reached its peak intensity that day, with 10-minute sustained winds of 110 km/h (70 mph) and a minimum barometric pressure of 980 hPa (28.94 inHg). Land interaction prevented further intensification, and it crossed into Quảng Ninh, Vietnam becoming the first tropical cyclone to hit mainland Vietnam in 640 days before weakening into a tropical depression on July 24.
