Part of the 2022 Pacific typhoon season |
Typhoon Nanmadol,known in the Philippines as Super Typhoon Josie,was a powerful tropical cyclone that impacted Japan. The fourteenth named storm,seventh typhoon,and second super typhoon of the 2022 Pacific typhoon season and the most intense tropical cyclone worldwide in 2022,Nanmadol originated from a disturbance to the east of Iwo Jima which the Joint Typhoon Warning Center (JTWC) designated as a tropical depression on September 12. Later that same day,upon attaining tropical storm strength,it was named Nanmadol by the Japan Meteorological Agency (JMA).
The storm gradually became better organized,with its sustained winds reaching typhoon strength two days later. It then underwent rapid intensification,with its wind speed increasing by 45 km/h (30 mph). Nanmadol peaked with winds of 195 km/h (120 mph) and a central pressure of 910 mbar (26.87 inHg) on September 17,and also briefly entered the Philippine Area of Responsibility,where it received the name Josie. Following peak intensity,the storm began an eyewall replacement cycle and tracked north towards Japan,where it made landfall on Southern Kyushu on September 18. Later,Nanmadol became a severe tropical storm on September 19,before transitioning into an extratropical low early the next day.
In preparation for the storm,more than half a million people were evacuated in Japan,a rare "special warning" was issued for Kagoshima by the JMA. [2] In Kagoshima,8,000 fled their homes,with another 12,000 in evacuation shelters. In South Korea,7,000 households also experienced power outages. [3] Four deaths were attributed to Nanmadol,all in Japan,and more than 115 people were injured,with most just being minor injuries. [4]
The origins of Typhoon Nanmadol can be traced back to an area of disturbed weather on September 9. [5] The disturbance favorable for development, being offset by warm sea surface temperatures of around 29–30 °C (84–86 °F). [5] A tropical depression developed, according to the Japan Meteorological Agency (JMA). [6] Satellite imagery revealed an obscure low-level circulation center. [5] Microwave imaging indicated a low-level circulation with a deep convection. [7] Formative banding blossomed around the disturbance and a LLC appeared on Himawari 8. [8] At 02:00 UTC on September 12, the United States Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert to the disturbance. [9] Later around the same day, the JTWC initiated advisories on the system and classified it as Tropical Depression 16W. [10] A broad low-level circulation with a disorganized over its convective. [11]
Six hours later, the JMA and the JTWC upgraded the system to a tropical storm, with the JMA assigning the name Nanmadol(2214) for the system. [12] [13] The low-level banding wrapped in the deepening LLC. [14] Nanmadol quickly intensified, and was upgraded to a severe tropical storm by the JMA on September 14. [15] Microwave imaging revealed a well-defined banding feeder from the north and south on the storm's quadrants. [16] Early the next day, the JTWC upgraded Nanmadol to a Category 1-equivalent typhoon, approximately 578 nautical miles (1,070 km; 665 mi) east-southeast of Kadena Air Base. [17] Convective banding and a ragged eye formed. [17] Similarly, the JMA further upgraded Nanmadol to a typhoon. [18] A central convection had dense, along with having colder convective tops. [19]
Nanmadol strengthened to a Category 2-equivalent typhoon after the inner core became more organized. [20] On September 16, the storm became a Category 3-equivalent typhoon and an eye that was trying to clear out. [21] Then, it rapidly strengthened into a Category 4-equivalent typhoon as it maintained a 15 nautical miles (28 km; 17 mi) sharply-outlined eye around the eyewall. [22] At around 15:00 UTC, the JTWC classified Nanmadol as a super typhoon. [23]
The JMA estimating a minimum central pressure of 910 hPa (26.87 inHg). [24] Nanmadol entered the Philippine Area of Responsibility, and was named Josie before eventually exiting 5 hours later. [25] Multispectral animated satellite imagery revealed a 21 nautical miles (39 km; 24 mi) surrounded eye around a deep convection. [26] The next day, Nanmadol weakened back to a Category 4-equivalent typhoon. [27] Satellite imagery revealed a rapid weakening on the system. [28] At 03:00 UTC on September 18, the JTWC further downgraded it to a Category 3-equivalent typhoon. [29] Nanmadol weakened further into a Category 2-equivalent typhoon as its structural strength began to rapidly deteriorate. [30] Nanmadol's were estimated at just 150 km/h (90 mph), which made it a Category 1-equivalent typhoon and made landfall over Southern Kyushu and a second landfall just south of Kagoshima around 18:00 UTC. [31] [32] At 00:00 UTC on September 19, the JMA downgraded Nanmadol to a severe tropical storm. [33] The JTWC followed suit later that day, and declaring it tropical storm. [34] Satellite imagery revealed a swallowing convection shearing in the northeastwards. [35] At 21:00 UTC that day, the JTWC issued their final warning on the system. [36] The JMA issued its last advisory on Nanmadol, and declared it an extratropical low on September 20. [37]
Nanmadol was forecasted to be among the top five strongest typhoons to hit Japan. [38] It was also predicted to interact with a jet stream, enhancing the risk of already concerning flooding. [39] A rare special warning was issued for Kagoshima by the JMA; before Nanmadol, these warnings were never issued outside of Okinawa. Japan Airlines and All Nippon Airways cancelled 700 flights, [40] and train services experienced severe delays. [2] Areas affected by Typhoon Hinnamnor two weeks prior were also anticipated to be under Nanmadol's influence. [41] Overall, nearly 7 million people were ordered to evacuate as the storm approached. [42] Of those 7 million, at least 965,000 were in Miyazaki, Kagoshima, and Amakusa. The highest alert on Japan's warning scale, level five, was issued for the city of Nishinoomote. [43]
Throughout the afternoon of September 18, Miyazaki saw over 15 inches of rain (381 mm) fall, where the JMA noted it was "raining like never before". Power lines were downed across affected areas, and at least 190,000 had experienced power outages [44] as Nanmadol passed. In Kagoshima, over 8,000 fled their homes with another 12,000 in evacuation shelters. Prime Minister Fumio Kishida mobilized police, firefighters, self-defense forces and another authorities in affected regions. [45] Several rivers in four prefectures, Kagoshima, Oita, Miyazaki and Kumamoto, went above flood risk levels. 100 dams were pre-discharged to prevent flooding, a higher number than the 76 discharged for Typhoon Haishen. [46] From September 15 to 19, 935 mm (36.8 in) of rainfall fell in Minamigo, and 784 mm (30.9 in) in Morozuka Village, and 669 mm (26.3 in) in Tojo City. [47]
At least 114 people were injured as Nanmadol passed. [48] At least most injuries were minor. [4] A crane from a construction site in Koryo-ocho had broken and nearly fell. Trees were fallen in affected areas, and many houses were damaged, injuring many residents in cities. Cars were trapped in roads due to flooding, and some people had to climb to the roof of their vehicles. A landslide in Tojo city left a road impassable. A nursing home was flooded in Nobeoka city, and temporary shelter buildings were blown away in Miyazaki city. In the latter city's prefecture, a month's worth of rain was dumped in a day. [49] [48] The highest rainfall total reached more than 39 inches of rainfall in Misato Town. [50] Higher-risk reinsurance arrangements were affected by Nanmadol. [51] At least four people were reported as killed in the country. [52]
Although South Korea was not directly hit by the typhoon, [53] the winds and rain caused by Nanmadol also caused inconvenience. Two people were injured, fallen trees were reported, and some locations in the southeast of the country were left without electricity. [3] [54] Nanmadol brought heavy rains in the Southeastern Gyeongsang. [55] 7,000 households also experienced a power outages. [3] Over 50 vessels in 43 routes were suspended. [55] President Yoon Suk-yeol instructed his officials to maintain readiness on the storm. [56] In Busan, 155 people and 103 households were evacuated from their homes. [3] Schools in Busan and Ulsan transitioned to distance learning due to safety concerns. [57] Some 101 passenger vessels, and over 79 routes in southern coast were suspended. [57]
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.
The 2011 Pacific typhoon season was a below average season that produced a total of 21 named storms, 8 typhoons, and four super typhoons. This season was much more active than the previous season, although both seasons were below the Pacific typhoon average of 26. The season ran throughout 2011, though most tropical cyclone tend to develop between May and October. The season's first named storm, Aere, developed on May 7 while the season's last named storm, Washi dissipated on December 19.
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 Bolaven, known in the Philippines as Typhoon Julian, was regarded as the most powerful storm to strike the Korean Peninsula in nearly a decade, with wind gusts measured up to 186 km/h (116 mph). Forming as a tropical depression on August 19, 2012, to the southwest of the Mariana Islands, Bolaven steadily intensified as it slowly moved west-northwestward in a region favoring tropical development. The system was soon upgraded to a tropical storm less than a day after formation and further to a typhoon by August 21. Strengthening became more gradual thereafter as Bolaven grew in size. On August 24, the system attained its peak intensity, with winds of 185 km/h (115 mph) and a barometric pressure of 910 mbar. Weakening only slightly, the storm passed directly over Okinawa on August 26 as it began accelerating toward the north. Steady weakening continued as Bolaven approached the Korean Peninsula and it eventually made landfall in North Korea late on August 28 before transitioning into an extratropical cyclone. The remnants rapidly tracked northeastward over the Russian Far East before turning eastward and were last noted on September 1 crossing the International Dateline.
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.
This timeline documents all of the events of the 2015 Pacific typhoon season. Most of the tropical cyclones formed between May and November. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. This area, called the Western Pacific basin, is the responsibility of the Japanese Meteorological Agency (JMA). They host and operate the Regional Specialized Meteorological Center (RSMC), located in Tokyo. The Japanese Meteorological Agency (JMA) is also responsible for assigning names to all tropical storms that are formed within the basin. However, any storm that enters or forms in the Philippine Area of Responsibility (PAR) will be named by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) using a local name. Also of note - the Western Pacific basin is monitored by the United States' Joint Typhoon Warning Center (JTWC), which gives all Tropical depressions a number with a "W" suffix.
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.
Severe Tropical Storm Pakhar, known in the Philippines as Tropical Storm Jolina, was a strong tropical storm that impacted South China during late August 2017. This storm followed Typhoon Hato which affected the area a few days prior. Pakhar was the fourteenth named storm of the Pacific typhoon season. Pakhar developed from a tropical depression to the east of Luzon during August 24, and intensified into a tropical storm later that day. Pakhar made landfall over in Aurora on August 25. Pakhar gradually intensified and peaked as a severe tropical storm by August 27, making landfall over Taishan, Jiangmen in Southern China.
The 2021 Pacific typhoon season was the second consecutive to have below average tropical cyclone activity, with twenty-two named storms, and was the least active since 2011. Nine became typhoons, and five of those intensified into super typhoons. This low activity was caused by a strong La Niña that had persisted from the previous year. The season's first named storm, Dujuan, developed on February 16, while the last named storm, Rai, dissipated on December 21. The season's first typhoon, Surigae, reached typhoon status on April 16. It became the first super typhoon of the year on the next day, also becoming the strongest tropical cyclone in 2021. Surigae was also the most powerful tropical cyclone on record in the Northern Hemisphere for the month of April. Typhoons In-fa and Rai are responsible for more than half of the total damage this season, adding up to a combined total of $2.02 billion.
The 2022 Pacific typhoon season was the third consecutive season to have below average tropical cyclone activity, with twenty-five named storms forming. Of the tropical storms, ten became typhoons, and three would intensify into super typhoons. The season saw near-average activity by named storm count, although many of the storms were weak and short-lived, particularly towards the end of the season. This low activity was caused by an unusually strong La Niña that had persisted from 2020. The season's first named storm, Malakas, developed on April 6, while the last named storm, Pakhar, dissipated on December 12. The season's first typhoon, Malakas, reached typhoon status on April 12. The season ran throughout 2022, though most tropical cyclones typically develop between May and October. Tropical storms Megi and Nalgae were responsible for more than half of the casualties, while typhoons Hinnamnor and Nanmadol both caused $1 billion in damages.
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. 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.
Typhoon Chanthu, known in the Philippines as Super Typhoon Kiko, was the second most intense tropical cyclone worldwide in 2021 after Typhoon Surigae in April. It impacted the Cagayan Valley region of the Philippines and became the strongest typhoon to affect the Batanes province since Typhoon Meranti in 2016. The twenty-ninth tropical depression, fourteenth named storm and fourth typhoon of the 2021 Pacific typhoon season, Chanthu originated from a disturbance well east of the Philippine islands on September 5 which organized into a tropical depression later that day. By the next day, the depression had formed into a mature tropical storm which began to explosively intensify by September 7, featuring a pinhole eye on satellite, characteristic of rapidly intensifying storms. Chanthu became a Category 5-equivalent super typhoon by September 8, the highest category on the Saffir–Simpson scale. Subsequent eyewall replacement cycles caused intensity fluctuations, but on September 10, Chanthu peaked with 1-minute sustained winds of 285 km/h (180 mph) just northeast of extreme northeastern Luzon. The typhoon passed very near the Babuyan Islands before passing directly over Ivana, Batanes as a weakening but still powerful Category 5-equivalent super typhoon. Chanthu continued steadily weakening as it passed just east of Taiwan and eventually stalled just east of Shanghai, China. The storm eventually made its second and final landfall near Ikitsuki, Nagasaki in Japan, before crossing the country's mountainous terrain and becoming an extratropical cyclone on September 18. Chanthu then continued eastward and curved southward, before dissipating on September 20. According to Aon Benfield, economic losses totaled US$30 million.
Typhoon Muifa, known in the Philippines as Typhoon Inday, was a powerful tropical cyclone that affected East China, Taiwan, and the Ryukyu Islands in mid-September 2022. It was the twelfth named storm and fourth typhoon of the 2022 Pacific typhoon season, having originated from an invest in the Pacific Ocean.
