Part of the 2012 Pacific typhoon season |
Typhoon Jelawat,known in the Philippines as Super Typhoon Lawin,was the most intense tropical cyclone of the 2012 Pacific typhoon season in terms of ten-minute maximum sustained winds,tied with Typhoon Sanba. Following Bolaven and Sanba,Jelawat was the third typhoon directly hitting Okinawa Island in 2012. Jelawat,which means carp in Malaysian,is a type of freshwater fish.
Jelawat reached peak intensity late on September 24 and maintained it for nearly two days. The typhoon passed through Okinawa Prefecture on September 29 and finally made landfall over Aichi Prefecture in Japan on September 30. Jelawat was the strongest typhoon for Okinawa Island in 2012 by observed winds,as it also killed 2 people in Japan. [1]
Late on September 17, a tropical disturbance formed east of Guam, and the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert on the system in the next two days, shortly before the Japan Meteorological Agency (JMA) upgraded the low-pressure area to a tropical depression early on September 20. [2] [3] Several hours later on September 20, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) upgraded the system to a tropical depression named Lawin, before JTWC also upgraded it to a tropical depression due to low vertical wind shear and improved equatorward outflow. [4] [5] Soon, JMA upgraded the system to a tropical storm and named it Jelawat, so did JTWC. [6]
Since September 21, Jelawat moved southwestwards slowly by tracking along the southwestern extension of the subtropical ridge anchoring east of Japan. Despite favourable conditions, the storm has struggled to improve its organization. [7] When Jelawat was drifting westwards by a weak steering environment on September 22, it intensified into a severe tropical storm for excellent equatorward outflow because of speedy divergence to the south, and a tropical upper tropospheric trough cell northeast of the system started to improved its poleward outflow. [8] Later, the system began to form an eyewall with excellent equatorward outflow and good poleward outflow. [9]
Based on the improved organization, both JMA and JTWC upgraded Jelawat to a typhoon early on September 23, before the system began to drift northwards due to a complex steering environment resulting from a trough over East Asia and a tropical depression (later becoming Severe Tropical Storm Ewiniar) in the east. [10] [11] Eighteen hours later, JTWC upgraded Jelawat to a super typhoon after the system underwent explosive intensification, becoming a well-developed system with a 10-nautical-mile (19 km; 12 mi) eye and strong spiral banding. [12]
Late on September 24, by low vertical wind shear and favourable outflow aloft across all quadrants, Typhoon Jelawat attained its peak intensity by the 10-minute maximum sustained winds reaching 110 knots (205 km/h, 125 mph) and the atmospheric pressure decreasing to 905 hPa (26.72 inHg). The typhoon also reached category 5 strength on the Saffir–Simpson hurricane wind scale, with a solid band of deep convection surrounding a 20-nautical-mile (37 km; 23 mi) eye. [13] Tracking northwestwards since September 25, Typhoon Jelawat entered an eyewall replacement cycle, and the process ended with a 25-nautical-mile (46 km; 29 mi) eye on the next day. [14]
Having maintained peak intensity for nearly two days because of excellent radial outflow enhanced by a poleward stream, Jelawat weakened slightly from late September 26 to early September 27, yet the diameter of that larger eye became 40 nautical miles (74 km; 46 mi). [15] Later, the system tracked northward, for a trough over East China was eroding the subtropical ridge. [16] When approaching Okinawa, Jelawat began to move northeastwards by tracking along the western edge of the subtropical ridge on September 28, and JTWC downgraded the system to a typhoon for a slight elongation in the overall shape. [17] At the same time, Jelawat weakened slightly due to another eyewall replacement cycle, but radial outflow and improving poleward outflow into a deep mid-latitude shortwave trough helped the typhoon maintain intensity. [18]
With a shrunken 7-nautical-mile (13 km; 8.1 mi) pinhole eye, Typhoon Jelawat passed through the west coast of Okinawa Island early on September 29, when the estimated 10-minute maximum sustained winds were at 90 knots (165 km/h, 105 mph). [19] Equatorward outflow has significantly hindered, as Jelawat started to gradually weaken; however, poleward outflow remained well-established and was linked to a deep mid-latitude trough directly to the north of the system. [20] Then, the typhoon accelerated northeastwards and moved into an area of strong southwesterly vertical wind shear, but jet-induced poleward outflow kept the system from rapid decaying. [21]
Since September 30, Jelawat was fully embedded in baroclinic zone and began extratropical transition, as the convective banding was unraveling. [22] At 06Z, JTWC downgraded Jelawat to a tropical storm, for deep convection was sheared to the north. [23] The system made landfall over Aichi Prefecture in Japan at 10Z, when the estimated 10-minute maximum sustained winds were at 70 knots (130 km/h, 80 mph). Eight hours later, JMA downgraded Jelawat to a severe tropical storm when it was located in Iwate Prefecture, and JTWC issued the final warning on the system simultaneously. [24] On October 1, JMA downgraded Jelawat to a tropical storm, shortly before becoming extratropical east of Kuril Islands. The extratropical cyclone strengthened and regained storm-force status on October 2, before the system crossed the International Date Line and began to weakened on October 3. [25] [26]
On September 29, 2012, Jelawat passed through Okinawa Prefecture. According to the Japan Meteorological Agency, the maximum gust produced by Typhoon Jelawat was at 62.6 m/s (225 km/h) in Miyagi Island of Uruma, Okinawa. [27] The maximum sustained winds were at 41.1 m/s (148 km/h) in Naha, ranked the tenth-strongest in that county seat and the largest city of Okinawa Prefecture on record. The storm also produced the maximum gust at 61.2 m/s (220 km/h) in Naha, ranked the third-strongest in that city on record. [28] [29]
Reports suggested that some 65 people were injured in the storm while 331,000 people remained without electricity. Strong winds flipped cars and uprooted trees. A four-ton truck was reportedly turned upside down by the winds causing a major roadblock in Naha. Flights and ferries connecting Okinawa to the rest of Japan were all cancelled. [30] Jelawat was known locally as Typhoon Seventeen. Up to 4,200 households in the regions of Higashi and Nago was asked to evacuate immediately. [31] Across Okinawa Prefecture, damage to agriculture amounted to ¥1.7 billion (US$21.6 million). [32]
In Japan, preparations for the storm started early on September 30. The storm was located nearly 220 km (140 mi) south of southwestern prefecture of Kochi, when officials warned the locals of strong wind, torrential rain, landslides and possible flash flooding. By then, Jelawat had already injured 96 people. [33] In Tokyo, several trains were cancelled and up to 300 flights to the city's Narita International Airport were cancelled. Up to 20 inches (510 mm) of rain was expected. [34] By October 1, one person had been killed and 140 other people were reportedly injured. Authorities in the central city of Nagoya have made it compulsory for 57,000 people to leave their homes in the wake of rising river levels in the city, which can cause significant flooding. [35] Among the dead was a 29-year-old man who was swept away by high waves while the typhoon was passing Okinawa. In Mie Prefecture, another 2,000 people were asked to evacuate. Waves as high as 10 metres (33 ft) were advised of. Meanwhile, in Tokyo, up to 500 millimetres (20 in) of rain was expected over the next 24 hours. Several other trains were cancelled and the total number of flights cancelled went up to 500. [36]
By the night of October 1, a 56-year-old man who had been missing since the past 24 hours was confirmed dead, after he had drowned. Local news agency, NHK, reported that over 181 people were injured in the typhoon. [37] A further 11,000 were told to evacuate in the city of Ishinomaki in the country's northeast, Jiji Press reported. The local Meteorological agency predicted rainfall of up to 400 millimetres (16 in) in some areas in the 24 hours. [38]
Total agricultural damage across the nation reached ¥8.935 billion (US$115 million). [39]
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 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 Damrey was a compact tropical cyclone, which became the strongest to affect the area north of the Yangtze River since 1949. It was the tenth named storm and the fifth typhoon of the 2012 Pacific typhoon season. The name Damrey means elephant in Khmer, the official language of Cambodia.
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.
Typhoon Francisco, known in the Philippines as Typhoon Urduja, was a powerful typhoon that strengthened to the equivalent of a Category 5 on the Saffir-Simpson scale, according to the Joint Typhoon Warning Center. The 25th named storm and the 10th typhoon of the 2013 Pacific typhoon season, Francisco formed on October 16 east of Guam from a pre-existing area of convection. With favorable conditions, it quickly intensified into a tropical storm before passing south of Guam. After stalling to the southwest of the island, Francisco turned to the northwest into an environment of warm waters and low wind shear, becoming a typhoon. The JTWC upgraded it to super typhoon status on October 18, while the Japan Meteorological Agency (JMA) estimated peak 10-minute sustained winds of 195 km/h (121 mph). Gradual weakening ensued, and after the typhoon turned to the northeast, Francisco deteriorated into a tropical storm on October 24. Passing southeast of Okinawa and mainland Japan, the storm accelerated and became extratropical on October 26, dissipating later that day.
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 Neoguri, known in the Philippines as Typhoon Florita, was a large and powerful tropical cyclone which struck Japan in 2014. The eighth named storm and the second typhoon of the annual typhoon season, Neoguri developed into a tropical storm on July 3 and then a typhoon on July 4. It rapidly deepened on July 5, reaching peak intensity late on July 6. Neoguri began to decay on July 7 and passed through Okinawa on July 8 and then making landfall over Kyushu as a severe tropical storm late on July 9. After Neoguri passed through the southern coast of Honshū on July 10, it became extratropical on July 11.
Typhoon Phanfone, known in the Philippines as Typhoon Neneng, was a powerful tropical cyclone which affected Japan in early October 2014. It was the eighteenth named storm and the eighth typhoon of the 2014 Pacific typhoon season. Phanfone started as a large area of convection well west of the International Date Line. The system was well organized and classified as Tropical Depression 18W on September 29. At the same day, it gained the name Phanfone due to very favorable conditions and intense thunderstorms rich with convection surrounding the storm's center. Phanfone would later go rapid intensification on October 1 due to warm sea-surface temperatures and very favorable environments. JTWC upgraded Phanfone to a Category 4 typhoon but weakened later back to Category 3 due to its eye replacing the old one and undergoing a minor eyewall replacement cycle.
Typhoon Vongfong, known in the Philippines as Super Typhoon Ompong, was the most intense tropical cyclone worldwide in 2014, and struck Japan as a large tropical system. It also indirectly affected the Philippines and Taiwan. Vongfong was the nineteenth named storm and the ninth typhoon of the 2014 Pacific typhoon season. Estimates assess damage from Vongfong to have been over US$160 million, mainly for striking mainland Japan. At least 9 people were killed along the path of the typhoon in those countries.
Typhoon Nuri, known in the Philippines as Super Typhoon Paeng, was the third most intense tropical cyclone worldwide in 2014. Nuri developed into a tropical storm and received the name Paeng from the PAGASA on October 31, before it intensified into a typhoon on the next day. Under excellent conditions, especially the synoptic scale outflow, Nuri underwent rapid deepening and reached its peak intensity on November 2, forming a round eye in a symmetric Central dense overcast (CDO). Having maintained the impressive structure for over one day, the typhoon began to weaken on November 4, with a cloud-filled eye.
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.
Typhoon Mindulle was a strong tropical cyclone which affected Japan in August 2016. The ninth named storm and second typhoon of the 2016 Pacific typhoon season, Mindulle was first noted as a low-pressure area northwest of Guam on August 17. Two days later, it was upgraded into a tropical storm, being named Mindulle. Gradually intensifying, Mindulle peaked as a Category 1-equivalent hurricane on the Saffir-Simpson scale on August 22 before making landfall in Chiba Prefecture later that day. Mindulle rapidly weakened, dissipating the next day.
Typhoon Malakas, known in the Philippines as Typhoon Gener, was a powerful tropical cyclone which affected Taiwan and Japan in mid September 2016. It was the sixteenth named storm and the sixth typhoon of the annual typhoon season in 2016. Malakas formed on September 11, just south of Guam. The system gradually organized and improved its outer bands, which prompted JTWC to give its identifier as Tropical Depression 18W. A few hours later, JMA received its name Malakas for 18W. On September 13, Malakas entered the Philippine Area of Responsibility, which gained the name Gener by PAGASA. Despite its marginal conditions for further development, Malakas continued to intensify into a typhoon.
Typhoon Chaba, known in the Philippines as Super Typhoon Igme, was the fourth most intense tropical cyclone in 2016 and the strongest tropical cyclone to make landfall in South Korea since Sanba in 2012. Chaba also caused 7 deaths in the country. Typhoon Chaba was the eighteenth named storm and the eighth typhoon of the 2016 Pacific typhoon season. Chaba originated as a depression around the east-northeast of Guam. Being in a marginally favorable environment, JMA proceeds to name the system as Chaba. On September 28, JTWC gave its identifier as Tropical Depression 21W. Its LLCC starts to improve, prompting the JTWC to upgrade into a tropical storm. Chaba entered the Philippine Area of Responsibility, receiving the name Igme as it moved northwestwards. Chaba became more symmetrical which later ensued its rapid intensification.
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.
Typhoon Lan, known in the Philippines as Super Typhoon Paolo, was the third-most intense tropical cyclone worldwide in 2017, behind only hurricanes Irma and Maria in the Atlantic. A very large storm, Lan was the twenty-first tropical storm and ninth typhoon of the annual typhoon season. It originated from a tropical disturbance that the United States Naval Research Laboratory had begun tracking near Chuuk on October 11. Slowly consolidating, it developed into a tropical storm on October 15, and intensified into a typhoon on October 17. It expanded in size and turned northward on October 18, although the typhoon struggled to intensify for two days. On October 20, Lan grew into a very large typhoon and rapidly intensified, due to favorable conditions, with a large well-defined eye, reaching peak intensity as a "super typhoon" with 1-minute sustained winds of 249 km/h (155 mph) – a high-end Category 4-equivalent storm – late on the same day. Afterward, encroaching dry air and shear caused the cyclone to begin weakening and turn extratropical, before it struck Japan on October 23 as a weaker typhoon. Later that day, it became fully extratropical before it was absorbed by a larger storm shortly afterward.
Typhoon Jelawat, known in the Philippines as Tropical Storm Caloy, was a powerful typhoon that affected the Caroline Islands in March 2018. The third tropical storm and the first typhoon of the 2018 Pacific typhoon season, Jelawat originated as a tropical disturbance that struck the Federated States of Micronesia before organizing into a tropical depression on March 24. It further intensified into a tropical storm on the following day, according to the Japan Meteorological Agency, receiving the name Jelawat. Drifting northward, the storm remained unorganized while staying east of the Philippines, though environmental conditions became more favorable along its path. On March 29, Jelawat took an unexpected sharp turn east as it intensified into a typhoon. Upon shifting northeast, Jelawat rapidly intensified on March 30 due to low vertical wind shear and substantial outflow, peaking as a Category 4-equivalent super typhoon. Shortly afterward, the storm began to weaken as wind shear sharply increased, falling below typhoon strength on March 31. The storm transitioned into a subtropical cyclone on April 1, before dissipating on that same day.
