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.
On August 16, a tropical disturbance formed southeast of Taiwan. [1] On August 17, the Japan Meteorological Agency (JMA) mentioned it as a tropical depression, as a subtropical ridge pushed the system southwards. [2] The Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert on the system late on August 18; [3] early the next day, the JMA upgraded it to a tropical storm and named it Tembin, and the JTWC upgraded it to a tropical depression. [4] [5] Soon, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) also upgraded it to a tropical depression and named it Igme. [6] On August 20, Tembin entered a period of explosive intensification, on encountering warm and deep Oceanic heat content. The JMA first noted this, and immediately upgraded Tembin into a Typhoon. [7] Only 3 hours later, the JTWC pointed out that an eye of radius 20 nautical miles (37 km; 23 mi) has formed under the low-level circulation center (LLCC) and is being powered by a self-induced meso-anticyclone. Also, there was an excellent poleward and equatorward outflow. A building western extension of a ridge close to the equator started showing a steering effect on the system, at that time. Tembin was expected to reach peak intensity within 48 hours. [8] Later that morning, Tembin contained tracking north-northeastward at 04 knots (7.4 km/h; 4.6 mph) while its eye grew a little large and its eyewall became more consolidated. The cloud-tops further cooled down and the eyewall was nearly symmetric. The poleward outflow was enhanced by a strong tropical upper tropospheric trough (TUTT). The windspeed rose from 65 knots (120 km/h; 75 mph) to 95 knots (176 km/h; 109 mph) within 6 hours. A deep mid-latitude trough across the Korean region resulting in a temporary slow-down or perhaps quasi-stationary motion east of Taiwan. [9] At the same time, the PAGASA updated Tembin, otherwise known as Igme, locally, to a typhoon. [10]
On August 20, by Tembin rapidly intensified, and its peak nearly on peak. By August 21, Tembin reached a maximum 1-minute sustained windspeed of 115 knots (213 km/h; 132 mph). The system maintained deep convective banding, tightly wrapped into a well-defined, small 10 nautical miles (19 km; 12 mi) eye surrounded by a highly symmetric eyewall. A nearby ridge started steering Tembin west. The JTWC were then anticipating a peak intensity of 130 knots (240 km/h; 150 mph). [11] Thereafter, the TUTT cell over the system started weakening it. The eyweall started getting eroded. The JTWC no longer expected Tembin to strengthen. [12] By that afternoon, it became clear that the weakening was the result of increased upper-level convergence caused by a rapidly strengthening TUTT extending southwestward from a TUTT cell. At that time, Tembin was tracking north-northwestward at 08 knots (15 km/h; 9.2 mph) and was located approximately 280 nautical miles (520 km; 320 mi) southeast of Taipei, Taiwan. A deep mid-latitude shortwave trough was tracking northeastward across eastern China. It was expected to track north of the system and then track into the Sea of Japan and steer Tembin westward. [13]
Later that night, Tembin slowed down on its track. Located approximately 255 nautical miles (472 km; 293 mi) southeast of Taipei, the system tracked north-northwestward at 05 knots (9.3 km/h; 5.8 mph) during the past six hours. Animated enhanced infrared satellite imagery showed that the system maintained overall tight consolidation and symmetry even as poleward outflow had slightly diminished. Upper level analysis indicated that Tembin sustained a mesoscale anticyclone that continues to provide good outflow despite two TUTT cells, one to the north and one to the southwest of the typhoon causing subsidence and strong shear along the west to southwestern flank. [14] On the morning on August 22, Animated multispectral satellite imagery showed that the central convection has slightly warmed as the overall structure became more elongated, an indication of increased shear. The system was tracking along the southwestern periphery of a deep-layered subtropical ridge to its north. [15]
Soon, it became clear that the typhoon started to undergo an eyewall replacement cycle. Satellite imagery showed a new eye-like feature developing within the system. Tembin continued weakening due to the eyewall replacement cycle and was expected to weaken even further at that moment. [16] Tembin continued to slow down on its track and remained almost stationary. Located approximately 210 nautical miles (390 km; 240 mi) southeast of Taipei, the storm system became a little less organized over the past couple of hours. Poleward outflow also started diminishing, as a result. [17] Track speeds continued to be slow as a primary steering influence, a deep layered subtropical ridge to the storm's north, was being weakened by a transiting mid-latitude trough located over the Korean Peninsula. Upper-level analysis indicated that the poleward outflow towards the tropical upper-tropospheric trough cell that was located over southern honshu shut down. [18]
Early on August 23, Tembin slowed down even further, to under 02 knots (3.7 km/h; 2.3 mph) towards the west. Microwave image revealed a nearly uniform concentric deep eyewall structure that was slightly fragmented over the southwestern quadrant. [19] Finally, a couple of hours later, Tembin started picking up track speed. A mesoscale anticyclone over the system generated excellent radial outflow. [20] Later that afternoon, Tembin re-intensified into a strong category 3 equivalent on the SSHS with winds of up to 105 knots (194 km/h; 121 mph) on the 1-minute sustained average. The dual banding features along the northern and southern halves continued feeding the low level circulation center. Upper level analysis indicated that the dual channel outflow to the poleward and equatorward directions had been instrumental in the system maintaining its intensity. [21]
At 19:00 UTC on August 23, Typhoon Tembin made landfall over Mudan Township in Pingtung, Taiwan, and it arrived the Taiwan Strait two hours later. [22] Early on August 24, the JTWC said that the eyewall structure had only slightly degraded as Tembin moved inland. Located approximately 180 nautical miles (330 km; 210 mi) south-southwest of Taipei, the storm system was drifting west-southwestward at nearly 10 knots (19 km/h; 12 mph). At that time, Tembin was expected to accelerate east-northeastward and interact with another nearby typhoon, Bolaven and go around Taiwan in loops. [23] Later that morning, animated multispectral satellite imagery depicted that the structure of the low level circulation center suffered a significant inflow issue as winds along the southeastern quadrant tracked over southern Taiwan. The JTWC declared that Tembin weakened into a strong Tropical Storm from a Typhoon as winds dropped to under 60 knots (110 km/h; 69 mph), although the Hong Kong Observatory kept it at typhoon status. An Advanced Scatterometer (ASCAT) pass revealed that winds along the western half of the system were in the 35 to 40 knot range, with a band of winds in the luzon strait showing 30 knots. [24]
Later that day, animated enhanced infrared satellite imagery depicted that the organization has been able to consolidate with convection beginning to wrap into the LLCC, as the LLCC was moving away from land. [25] While tracking west-southwestward at nearly 07 knots (13 km/h; 8.1 mph), convection started to wrap anew into the LLCC. A microwave eye feature was also observed. Upper level analysis indicated a weak point source anticyclone that continued providing good outflow and low vertical wind shear environment. After developing an eye, Tembin rapidly intensified into a category 3 typhoon, before gradually weakening due to an easterly wind shear from Bolaven, which caused the LLCC to become slightly exposed, associated with a few burst of convection, and made its closest approach to Taiwan on 17:30(UTC) as a tropical storm. [26] [27] [28]

Early on August 28, Tembin entered the East China Sea, after making a circle back toward Taiwan as a tropical storm. By August 28, due to land interaction and wind shear from the northeast by a ridge, Tembin's exposed low level circulation center become partially exposed, with deep convection burst on the southern portions of the LLCC. [29] [30]
By August 29, Tembin was charging towards the South Korea. At 01:30 UTC on August 30, Tembin made landfall over Boseong County, South Jeolla Province, South Korea as a tropical storm.[ citation needed ]
Tembin brought flash flooding to Luzon, killing 8 people and 3 others went missing. Agricultural damage amounted to be PHP4.09 million (US$96,000). [31]
On August 21, the Central Weather Bureau in Taiwan issued a sea warning for Typhoon Tembin, predicting strong winds, heavy rains and storm surge. The residents of Yilan, Hualien, and Taitung were asked to stay alert regarding the storm system. [32] By August 22, the Ministry of National Defense of Taiwan helped evacuate several residents in the typhoon-prone areas and provided accommodation to some in their own military camps. More than 49,000 soldiers were on standby to provide relief and rescue to those in need when the typhoon strikes. About 107 military bases in and around the typhoon-prone regions were ready to provide shelter to well over 53,000 evacuees. [33] The next day, Taiwanese authorities evacuated another 3000 residents from mountainous areas anticipating torrential rain that could cause landslides. [34] Later that day, the outer rainbands of Tembin started brushing Taiwan. The system unexpected sped up towards land and started re-intensifying. [35] Late that night numerous cities and counties across the island shut down schools and offices for up to two days. [36] Farmers also immediately harvested their crops like they earlier did in 2010 anticipating Fanapi's arrival. People in eastern Taiwan boarded up their windows to try to minimize structural damage. Valentine's Day celebrations across Taiwan were also cancelled. [37]
On August 24, Tembin made landfall in southern Taiwan. The storm poured torrential rains, toppled trees, and caused flash flooding in several farmlands. Reportedly, 167.5 mm (6.59 in) of rain fell within one hour, the heaviest downpour in over 100 years. [38] The local weather bureau data showed Pingtung as a whole received 724 mm (28.5 in) of rain since August 22. [39] The typhoon dropped up to 500 millimetres (20 in) of rainfall on Hengchuen during the overnight of August 23. [40] Hengchun also recorded its highest rainfall since 1896. [39] However, the most heavily populated areas were spared as the storm quickly reemerged into sea. Authorities in Pingtung reported that the town of Hengchun was hit by heavy flooding, with waters reaching 3 m (9.8 ft) high in some places. Northern Taiwan was largely spared and schools and offices in the region remained open. Flights to and from southern Taiwan were also cancelled as the typhoon struck. [41] In some parts of southern Taiwan, Tembin blew off the rooftops of many houses. The toppled trees covered busy roads leading to severe traffic jams. Police also intentionally set up roadblocks in some regions anticipating landfalls. [42] Despite no casualties, livelihoods of farmers and poor slum-dwellers were significantly affected by the typhoon. An official of the local highway administration said that the situation would have been even worse if the highways were not blocked. [43] On August 25, about 500 military personnel helped clean up flooded areas in Hengchun. The power outages and roadblocks were cleared by then. Also, railway services between Neishih and Fangshan which were earlier affected by the storm were restored after intensive repair work that, as the Taiwan Railways Administration claims, was done overnight. [38]
At the same time, Taiwan forecasters warned residents that tropical storm Tembin could return early next week. Tembin was interacting with nearby Typhoon Bolaven and was expected to go around in loops, eventually making a second landfall over Taiwan. "Flooding in the Hengchun area Friday was very serious, and worse even than Morakot," said Chen Cheng-chia, a Pingtung Fire Agency official. [39] later reports revealed that at least 5 people had been injured while the typhoon made its first landfall. [44] Agricultural damage across the island reached NT$196.87 million (US$6.57 million). [45]

Following on the heels of Typhoon Bolaven, Tropical Storm Tembin brought further impacts to South Korea. Some areas received up to 150 mm (5.9 in) of rain, leading to several landslides. In Cheonan, one person was killed in a landslide. A second person was killed in Yeongam after strong winds toppled a large iron gate. [46]
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.
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 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 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 Kai-tak, known in the Philippines as Severe 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 wind speed 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.
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.
Typhoon Usagi, known in the Philippines as Super Typhoon Odette, was a violent tropical cyclone which affected Taiwan, the Philippines, China, and Hong Kong in September 2013. Usagi, or which means the constellation Lepus in Japanese, was the fourth typhoon and the nineteenth tropical storm in the basin. Developing into a tropical storm east of the Philippines late on September 16, Usagi began explosive intensification on September 19 and ultimately became a violent and large typhoon. Afterwards, the system weakened slowly, crossed the Bashi Channel on September 21, and made landfall over Guangdong, China on September 22.
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 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 Dujuan, known in the Philippines as Super Typhoon Jenny, was the second most intense tropical cyclone of the Northwest Pacific Ocean in 2015 in terms of ten-minute maximum sustained winds, tied with Noul. The twenty-first named storm and the thirteenth typhoon of the 2015 Pacific typhoon season, Dujuan brought extremely powerful winds throughout the Yaeyama Islands and Taiwan in late September, causing 3 deaths in Taiwan. The typhoon also caused over ¥2.5 billion (US$392.9 million) damage in East China.
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.
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 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.
Typhoon Hato, known in the Philippines as Severe Tropical Storm Isang, was a strong tropical cyclone that struck South China in August 2017. The thirteenth named storm and the fourth typhoon of the Pacific typhoon season, Hato formed as a tropical depression over the east of Luzon on 19 August. The system further developed and became a tropical storm the next day. On 21 August, Hato emerged over the northern portion of the South China Sea and reached typhoon intensity. Rapid intensification ensued on 23 August, and Hato became a Category 3-equivalent typhoon before making landfall over Jinwan, Zhuhai. The storm further weakened over land and dissipated on 24 August.
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 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.
Typhoon Jongdari was a strong, long-lived and erratic tropical cyclone that impacted Japan and East China in late July and early August 2018. Formed as the twelfth named storm of the 2018 typhoon season near Okinotorishima on July 24, Jongdari gradually intensified and developed into the fourth typhoon of the year on July 26. Influenced by an upper-level low and a subtropical ridge, Jongdari executed a rare counter-clockwise southeast of Japan on the next day. At that time, it also reached peak intensity. The typhoon made landfall in Kii Peninsula, over Mie Prefecture of Japan locally early on July 29.
