The origin of Typhoon Dujuan can be traced back to a tropical disturbance that formed over the Maloelap Atoll late on September 14. [1] Convection remained very fragmented until September 20, when the Japan Meteorological Agency (JMA) upgraded the low-pressure area to a tropical depression east-northeast of Guam early on that day. [2] [3] Moreover, the Joint Typhoon Warning Center (JTWC) started to issue a Tropical Cyclone Formation Alert at the same time and indicated a monsoon depression, although the low-level circulation center (LLCC) was exposed and located east of the deep convective banding. [4] In the afternoon on September 21, the JMA began to issue tropical cyclone warnings to the system, shortly before the JTWC also upgraded it to a tropical depression and designated it as 21W, based on the convective structure and a RapidSCAT image. [5] [6] On September 22, although the structure remained asymmetric with a fully exposed LLCC under easterly moderate vertical wind shear, the system still intensified into a tropical storm late on the same day and received the name Dujuan from the JMA. [7] [8]

Many meteorological agencies initially forecasted a recurving track south of Japan to Dujuan, but those agencies changed it to a west-northwest track pointing to Taiwan after 24 hours. [9] Dujuan developed smaller vortices rotating around a larger circulation centroid with deep convection along the western periphery on September 23; [10] however, right after the storm entered the Philippine Area of Responsibility and was named Jenny by PAGASA, there was only one partially exposed LLCC within the consolidating structure in the afternoon, leading more model guidances to show a stairstep track vice a recurve scenario. [11] [12] When moving and organizing slowly on September 24, Dujuan was upgraded to a severe tropical storm early on that day, with an apparent eye revealed by a microwave imagery. [13] [14] Based on a ragged eye under decreasing vertical wind shear, both of the JTWC and then the JMA upgraded Dujuan to a typhoon early on September 25, as the system started to track northwestward along the southwestern periphery of a deep-layered subtropical ridge. [15] [16] [17]

Good divergent outflow as well as low vertical wind shear allowed Dujuan to intensify stably on September 26, yet dry air and subsidence were impacting the system at the same time, causing the western eyewall to break down. [18] Due to decreasing dry air, Dujuan improved its overall structure significantly late on the same day when starting to track west-northwestward. [19] Due to sea surface temperatures of 29 °C and improved radial outflow enhanced by a microscale anticyclone aloft, the JTWC indicated that the typhoon with an enlarged 80 km (50 mi) eye embedded in the highly deep and symmetric core had one-minute maximum sustained winds at 230 km/h (140 mph) early on September 27, equivalent to Category 4 of the Saffir–Simpson hurricane wind scale. [20] This was increased to 240 km/h (150 mph) in post-season reanalysis, making Dujuan a super typhoon. Right after record-breaking winds were observed in Yonaguni of Okinawa, Japan around 16:00 JST (07:00 UTC) on September 28, the JMA raised Dujuan's estimated intensity of ten-minute maximum sustained winds to 205 km/h (127 mph) immediately, although the deep convective banding had begun to loosen with unraveling along the western side. [21] [22]

Soon, the eye shrunk quickly and became cloud-filled when the eyewall was interacting with the terrain of Taiwan, indicating a weakening trend from both the JMA and the JTWC. [23] The Central Weather Bureau (CWB) announced that Typhoon Dujuan had made landfall over Nan'ao, Yilan at 17:40 TST (09:40 UTC); [24] at around 01:00 TST on September 29 (17:00 UTC on September 28), Dujuan emerged into the Taiwan Strait from Fangyuan, Changhua. [25] Severely eroded by the Central Mountain Range and the Xueshan Range in Taiwan, the system rapidly weakened and was downgraded to a severe tropical storm by the JMA at 00:00 UTC on September 29. [26] [27] Dujuan made its second landfall over Xiuyu District, Putian of Fujian, China at around 08:50 CST (00:50 UTC) on September 29, shortly before the JTWC issued the final warning. [28] [29] The JMA downgraded the system to a tropical storm at 06:00 UTC and then a tropical depression at noon. [30] [31] One day later, the system was absorbed into a stationary front which later became a powerful extratropical cyclone. [32] [33]

Impact and records

Japan

Maximum wind speed in Yonaguni on September 28, 2015

Typhoon Dujuan brought extremely powerful sustained winds and gusts in the Yaeyama Islands on September 28. The Yonaguni weather station observed a maximum gust of 81.1 m/s (292 km/h) and maximum 10-minute sustained winds at 54.6 m/s (197 km/h), surpassing all previous records on the island; based on the observations in Yonaguni, Dujuan caused the fourth strongest gust and the seventh strongest sustained winds in the history of Japan, and that gust was also the strongest in Japan since September 1966. [34] The typhoon also broke the record of maximum sustained winds near the Yonaguni Airport (Tokorono), which observed 42.6 m/s (153 km/h). Overall, five weather stations throughout the Yaeyama Islands observed hurricane-force sustained winds from Dujuan. [35]

Agricultural damage throughout Okinawa Prefecture is estimated at ¥180.1 million (US$1.5 million), [36] including ¥127.58 million (US$1.06 million) in Yaeyama Islands. [37] 322 houses in Yonaguni were damaged, and 10 of them were completely destroyed by the typhoon. [38] Roofs of many schools and gymnasium halls were blown away on the island, and products such as sugar canes were severely damaged. All cargo ships and ferries to Yonaguni were suspended during Dujuan, including a large cargo which carries everyday goods from main islands of Okinawa. A power outage also affected about 400 houses in Yonaguni. [39]

Taiwan

Typhoon Dujuan caused three deaths and 376 injuries in Taiwan. A female driver went into a skid and crashed in Nangang District, Taipei. She died later after being sent to a hospital. In Tucheng District, New Taipei, an elderly man died after being knocked down by strong winds. A group of people tried to fix a fallen fence at a construction site in Beitun District, Taichung; however, when a man was standing on a corrugated sheet, strong winds rolled them up. The man died due to a three-meter fall. Over 2.25 million houses throughout Taiwan suffered from power outage, and over 180 thousand houses in Taipei and New Taipei faced water outage. [40]

Preliminary losses to agriculture are estimated at NT$217.01 million (US$6.59 million), and Yunlin County suffered the biggest losses, estimated at NT$82.89 million (US$2.49 million), accounting for 38 percent of the country's total losses. Losses in the category of crops were estimated at NT$201.45 million (US$6.05 million), with 8,018 hectares affected. [41] Heavy rainfall on September 28 and 29 led to serious rockslides at a section of the Alishan Forest Railway which was destroyed by Typhoon Morakot and reconstructed recently, ruining plans by the Taiwan Railways Administration to reopen the full length of the railway on December 25. [42]

Bon Jovi's only two concerts at the Taipei World Trade Center Nangang Exhibition Hall on September 28 and 29 were canceled due to Typhoon Dujuan, as the Taipei City government announced school and office closures for the two days. [43] During the first landfall, the weather station in Su'ao, Yilan observed the maximum gust at 68.4 m/s (246 km/h) and maximum sustained winds at 40.4 m/s (145 km/h), and that gust became the second strongest of the station in history. [44] [45] [46]

China

Across East China, nearly 1.7 million people were affected by the typhoon. [47] [48] The most severe damage took place in Fujian Province where 400 homes collapsed, 31,000 hectares (77,000 acres) of farmland were flooded, and total economic losses reached ¥2.4 billion (US$377.5 million). [48] Total economic damage in East China were at ¥2.536 billion (US$398.5 million). [49]

<span class="mw-page-title-main">Typhoon Soudelor</span> Pacific typhoon in 2015

Typhoon Soudelor, known in the Philippines as Typhoon Hanna, was the third most intense tropical cyclone worldwide in 2015 after Hurricane Patricia and Cyclone Pam as well as the strongest tropical cyclone of the 2015 Pacific typhoon season. Soudelor had severe impacts in the Northern Mariana Islands, Taiwan, and eastern China, resulting in 40 confirmed fatalities. Lesser effects were felt in Japan, South Korea and the Philippines. The thirteenth named storm of the annual typhoon season, Soudelor formed as a tropical depression near Pohnpei on July 29. The system strengthened slowly at first before entering a period of rapid intensification on August 2. Soudelor made landfall on Saipan later that day, causing extensive damage. Owing to favorable environmental conditions, the typhoon further deepened and reached its peak intensity with ten-minute maximum sustained winds of 215 km/h (134 mph) and a central atmospheric pressure of 900 hPa on August 3. The Joint Typhoon Warning Center assessed one-minute sustained winds at 285 km/h (177 mph), making Soudelor a Category 5-equivalent super typhoon. Steady weakening ensued thereafter as the storm moved generally west-northwest. Soudelor made landfall over Hualien, Taiwan, late on August 7 and emerged over in the Taiwan Strait early the next day. The typhoon soon moved inland over eastern China and degraded to a tropical depression by August 9.

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.

It was the ninth named storm and the second typhoon of the annual typhoon season. After consolidating slowly for several days, Tropical Storm Nesat developed east of the Philippines on July 25. While experiencing favorable environmental conditions such as very warm sea surface temperatures and low wind shear, Nesat strengthened into a typhoon and reached its peak intensity on July 28. On July 29, the typhoon made landfall near the Taiwanese city of Yilan, before weakening to a severe tropical storm and making landfall again near Fuqing on China's east coast late the same day. Moving into July 30, Nesat continued to weaken under the effects of land interaction.

<span class="mw-page-title-main">Typhoon Lan</span> Pacific typhoon in 2017

Typhoon Lan, known in the Philippines as Typhoon Paolo, was the third-most intense tropical cyclone worldwide in 2017. 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.
