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.
Muifa originated from a disturbance near the Philippine Sea,slowly tracking westward until its development into a tropical depression,where it began to move south westward. Muifa underwent rapid intensification as it approached eastern China,with maximum sustained winds of up to 155 km/h (95 mph) Right before its first landfall,Muifa was downgraded to a Category 3,then Muifa made its first landfall over eastern China on September 13 as a category 1.
The origins of Typhoon Muifa can be traced back to an area of disturbed weather on September 5. [2] The disturbance favorable vertical wind shear, being offset by warm sea surface temperatures of around 30–31 °C (86–88 °F). [2] A low-pressure area developed into a tropical depression, according to the Japan Meteorological Agency (JMA). [3] [4] Multispectral animated satellite imagery revealed a partially exposed low-level center with deep convection to the southeastern quadrant of its disturbance. [5] At 06:00 UTC on September 6, the United States Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert to the exposed system. [6]
Later around the same day, the JTWC initiated advisories on the system and classified it as Tropical Depression 14W. [7] A broad low-level circulation indicate the development of a vertical hot tower over its convective. [8] Early the next day, the JTWC upgraded the depression to a tropical storm. [9] It eventually entered the Philippine Area of Responsibility (PAR) with PAGASA assigning the name Inday. [10] Deepest formative maintained with a ragged central dense overcast continued to obscure low-level circulation center. [11] By 00:00 UTC on September 8, the JMA upgraded the system to a tropical storm, assigning it the name Muifa. [12] Muifa's center was elongated due to a tropical upper tropospheric trough from the north on the system. [13] A well-defined deep convection is wrapped around the northwestern portions of the storm. [14] Muifa's convective structure continued to improve as it flared up and rotated shear. [15] microwave imaging revealed a developing, eye like-feature. [15]
The storm's quickly intensified, and was upgraded to a severe tropical storm by the JMA on September 9. [16] At 21:00 UTC that day, the JTWC also upgraded Muifa to a Category 1-equivalent typhoon, approximately 388 nautical miles (720 km; 445 mi) south of Kadena Air Base. [17] Muifa convective activity had improved overall. [17] Similarly, the JMA further upgraded Muifa to a typhoon on September 10. [18] Muifa strengthened to Category 2-equivalent typhoon after deep convection becoming more symmetric in the 24 nautical miles (44 km; 28 mi) eye. [19] Within the next three hours, the storm became a Category 3-equivalent typhoon. [20]
Satellite imagery revealed a 20 nautical miles (37 km; 23 mi) round eye with core convection in the eyewall. [21] Then, it rapidly strengthened into a Category 4-equivalent typhoon on September 11. [22] Muifa weakened back to Category 3-equivalent due to undergoing an eyewall replacement cycle. [23] At 03:00 UTC on September 12, Muifa further weakened into a Category 2-equivalent typhoon as it wrapped around the eyewall. [24] Muifa, then weakened steadily as it made landfall in Ishigaki Island. [25]
Muifa exited the PAR at 12:40 PHT (4:40 UTC) on September 13. [26] [27] Satellite imagery revealed a 30 nautical miles (56 km; 35 mi) ragged eye around a convective banding. [28] A well defined system with its deep convection wrapped around it. [29] its eye structure slowly degraded. [30] At 15:00 UTC on September 14, the JTWC further downgraded it to a Category 1-equivalent typhoon. [31] The storm made landfall at this intensity on Zhoushan Island, [32] before making a second landfall in Shanghai. [33] It is the most powerful typhoon to strike Shanghai on record, [34] [35] beating out the previous record of Typhoon Gloria in 1949. [36] Meanwhile, the JMA downgraded the system to a severe tropical storm by 21:00 UTC of that day. [37] At 03:00 UTC on September 15, the JTWC downgraded it to a tropical storm. [38] Muifa made third and fourth landfalls on Shandong and Liaoning. [39] [40] The JMA followed suit later that day, and declaring it tropical storm. [41] Muifa continued to deteriorate as it tracked the Yellow Sea, and later dissipated late on September 16. [42]
Muifa caused many high waves and mudslides throughout the Ryukyu Islands. Heavy rain hit Ishigaki Island. [43]
Taiwan was hit by 140 km (86 mph) winds. [44] Heavy amounts of rain hit Keelung, Taipei, Hsinchu, and Taichung. The Council of Agriculture (COA) issued 15 "red alerts" and 14 "yellow alerts" for landslides throughout Northern Taiwan. [45]
Muifa caused much damage and heavy rainfall throughout Eastern China, most of it in towns close to the populous Yangtze River delta. Over 230 million people were affected in throughout the delta, with over 1.3 million people evacuated from Zhoushan, where powerful rain bands hit the city. [46] Muifa brought heavy rains to Shanghai, resulting in many ports near the city being closed. Ferry and shipping traffic was suspended and fishing boats were called into port. Ports near Ningbo were closed. [47]
Heavy rain hit North Korea. [48]
The 2012 Pacific typhoon season was a slightly above average season produced 25 named storms, fourteen typhoons, and four intense typhoons. It was a destructive and the second consecutive year to be the deadliest season. 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.
Tropical Storm Higos, known in the Philippines as Tropical Storm Pablo, was a tropical storm during the 2008 Pacific typhoon season. The name "Higos" is the Chamorro word for fig.
Typhoon Kujira, known in the Philippines as Typhoon Dante, was first reported by the Joint Typhoon Warning Center (JTWC) on April 28. It was the fourth depression and the first typhoon of the season. The disturbance dissipated later that day however it regenerated early on April 30 within the southern islands of Luzon. It was then designated as a Tropical Depression during the next morning by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) and the Japan Meteorological Agency (JMA), with PAGASA assigning the name Dante to the depression. However the JTWC did not designate the system as a depression until early on May 2 which was after the depression had made landfall on the Philippines. Later that day Dante was upgraded to a Tropical Storm and was named as Kujira by the JMA. The cyclone started to rapidly intensify becoming a typhoon early on May 4, and then reaching its peak winds of 155 km/h (100 mph) (10-min), 215 km/h (135 mph) (1-min) later that day after a small clear eye had developed.
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 2015 Pacific typhoon season was a slightly above average season that produced 27 tropical storms, 18 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.
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.
Severe Tropical Storm Talas, was an unusually large tropical cyclone that caused many deaths and severe damage to Japan. It was the 12th named storm and the 7th severe tropical storm of the 2011 Pacific typhoon season. Talas is known to have killed at least 82 people, and 16 more are still missing. The word Talas is a Filipino word meaning sharpness. It followed five months after Japan was hit by a large tsunami.
Typhoon Kai-tak, known in the Philippines as Tropical Storm Helen, was a mild tropical cyclone that affected China, Vietnam and Laos. It was the seventh typhoon and the thirteenth named storm of the 2012 Pacific typhoon season. The storm killed 41 people and caused a sum of US$765 million in losses. Kai-tak can be tracked back to the broad area of disturbance embedded in a monsoonal trough that was first spotted, early on August 10. It was only at midnight, on August 16, when the JMA officially declared Kai-tak a typhoon. On the morning of August 17, the windspeed dropped to 60 knots and was no longer a typhoon. The typhoon caused heavy damage in China's two provinces killing four people and causing huge economic loss. Kai-Tak slammed the northern Philippines triggering flash floods and landslides and killing at least ten people, one week after deadly monsoon rains battered the country. In Vietnam, Kai-Tak has stormed across the country's north bringing high winds and floods to several areas including the capital Hanoi.
This timeline documents all of the events of the 2012 Pacific typhoon season, the period that tropical cyclones formed in the Western Pacific Ocean during 2012. Most of these tropical cyclones formed between May and November 2012. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. Tropical storms that form in the entire Western Pacific basin are assigned a name by the Japan Meteorological Agency (JMA). Tropical depressions that form in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center (JTWC). In addition, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones that enter or form in the Philippine area of responsibility. These names, however, are not in common use outside of the Philippines.
Typhoon Hagupit, known in the Philippines as Super Typhoon Ruby, was the second most intense tropical cyclone in 2014. Hagupit particularly impacted the Philippines in early December while gradually weakening, killing 18 people and causing $114 million of damage in the country. Prior to making landfall, Hagupit was considered the worst threat to the Philippines in 2014, but it was significantly smaller than 2013's Typhoon Haiyan.
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 Nock-ten, known in the Philippines as Super Typhoon Nina, was the strongest Christmas Day tropical cyclone worldwide in terms of 1-minute sustained winds. Forming as a tropical depression southeast of Yap and strengthening into the twenty-sixth tropical storm of the annual typhoon season on December 21, 2016, Nock-ten intensified into the thirteenth typhoon of the season on December 23. Soon afterwards, the system underwent explosive intensification and became a Category 5-equivalent super typhoon early on December 25. Nock-ten weakened shortly afterwards before making eight landfalls over the Philippines. The typhoon weakened rapidly due to the landfalls as it entered the South China Sea on December 26, turned southwest, and ultimately dissipated on December 28 due to the winter monsoon.
Typhoon Noru was the second-longest-lasting tropical cyclone of the Northwest Pacific Ocean on record—behind only 1986's Wayne and tied with 1972's Rita—and the second-most-intense tropical cyclone of the basin in 2017, tied with Talim. Forming as the fifth named storm of the annual typhoon season on July 20, Noru further intensified into the first typhoon of the year on July 23. However, Noru began to interact with nearby Tropical Storm Kulap on July 24, executing a counterclockwise loop southeast of Japan. Weakening to a severe tropical storm on July 28, Noru began to restrengthen as it turned sharply to the west on July 30. Amid favorable conditions, Noru rapidly intensified into the season's first super typhoon, and reached peak intensity with annular characteristics on July 31. In early August, Noru underwent a gradual weakening trend while curving northwestwards and then northwards. After stalling off the Satsunan Islands weakening to a severe tropical storm again on August 5, the system began to accelerate northeastwards towards the Kansai region of Japan, making landfall in Wakayama Prefecture on August 7. Noru became extratropical over the Sea of Japan on August 8, and dissipated one day later.
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, of which ten became typhoons, and three intensified into super typhoons. The season saw a slightly below 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.
Tropical Storm Son-Tinh, known in the Philippines as Tropical Storm Henry, was a weak but very deadly tropical cyclone that devastated Vietnam and Laos in July 2018. Son-Tinh originated from an area of low pressure over the Philippine Sea on July 15, 2018. Moving quickly westwards, Son-Tinh strengthened to the ninth tropical storm of the annual typhoon season on July 17. Intensifying only slightly while crossing the South China Sea, Son-Tinh made its first landfall over Hainan Island on July 18. After emerging into the Gulf of Tonkin, Son-Tinh restrengthened before making its second landfall as a tropical storm in Northern Vietnam on July 19. Once inland, Son-Tinh weakened into a low pressure area as it slowed and made a clockwise loop. The remnants of Son-Tinh then emerged back over water and regenerated into a tropical depression late on July 21.
Tropical Storm Barijat, known in the Philippines as Tropical Storm Neneng, was a weak tropical storm that caused flooding in the far northern regions of the Philippines and Southern China. The thirty-third tropical depression and twenty-third tropical storm of the 2018 Pacific typhoon season, it was first noted as an area of convection in the South China Sea on September 6. On September 8, it was upgraded to a tropical depression, and by September 11, it intensified into a tropical storm, with the Japan Meteorological Agency (JMA) giving it the name Barijat. Barijat peaked in intensity 6 hours later, with 10-min winds of 40 knots and 1-min winds of 45 knots. Barijat continued westward, and on November 12 at 00:30 UTC, it made landfall over Zhanjiang, quickly dissipating afterwards.
Typhoon Chanthu, known in the Philippines as Super Typhoon Kiko, was a very powerful tropical cyclone which 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 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).
Typhoon Mindulle was a long-lived and strong typhoon that lasted out the sea. As the seventeenth named storm, and the sixth typhoon of the 2021 Pacific typhoon season, Mindulle originated from a area of low pressure 703 nmi southeast of Guam. It quickly organized until attaining the name Mindulle. Mindulle eventually became a Category 1 typhoon on September 25 in 3:00 UTC. Wind shear slowed its rapid intensification, but it still managed to intensify. Mindulle eventually reached Category 5 typhoon the next day, as the storm had a large eye in its center. Wind shear weakened the storm, but reintensified. On October 2, JMA issued its last advisory as it becomes extratropical as it continues moving northeast.
