2021 Pacific Typhoon Season
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 $2.017 billion. The scope of this article is limited to the Pacific Ocean to the north of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhoon Surigae
Typhoon Surigae, known in the Philippines as Super Typhoon Bising, was the strongest Northern Hemisphere tropical cyclone to form before the month of May, one of the most intense tropical cyclones on record and the strongest tropical cyclone worldwide in 2021. The second named storm, first typhoon and the first super typhoon of the 2021 Pacific typhoon season, Surigae originated from a low-pressure area south of the Micronesian island of Woleai that organized into a tropical depression on April 12. At 18:00 UTC that day, it strengthened to a tropical storm and was named ''Surigae'' by the JMA. The formation of an eye and increasing winds prompted the JMA to upgrade the system to a severe tropical storm on April 13. The storm proceeded to gradually strengthen, and late on April 15, Surigae became a typhoon. Very favorable environmental conditions then allowed Surigae to rapidly intensify; on the next day Surigae became a super typhoon, and by April 17, the storm reached its peak ...

Japan Meteorological Agency
The , abbreviated JMA, is an agency of the Ministry of Land, Infrastructure, Transport and Tourism. It is charged with gathering and providing results for the public in Japan that are obtained from data based on daily scientific observation and research into natural phenomena in the fields of meteorology, hydrology, seismology and volcanology, among other related scientific fields. Its headquarters is located in Minato, Tokyo. JMA is responsible for gathering and reporting weather data and forecasts for the general public, as well as providing aviation and marine weather. JMA other responsibilities include issuing warnings for volcanic eruptions, and the nationwide issuance of earthquake warnings of the Earthquake Early Warning (EEW) system. JMA is also designated one of the Regional Specialized Meteorological Centers of the World Meteorological Organization (WMO). It is responsible for forecasting, naming, and distributing warnings for tropical cyclones in the Northwestern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhoon Cempaka
Typhoon Cempaka was a moderately-strong and fairly long-lived tropical cyclone that caused substantial damage in China and Vietnam toward the end of July 2021. The seventh named storm and the fourth typhoon of the 2021 Pacific typhoon season, the storm formed from a tropical disturbance west of the Philippines on July 17. Around the same time, the JMA recognized the system as a tropical depression, with the JTWC issuing a TCFA for the disturbance. The storm slowly moved northwestward towards China, and on July 19, the system strengthened into a tropical storm and was given the name ''Cempaka'' by the JMA. On the next day, Cempaka reached its peak intensity, peaking as a Category 1-equivalent typhoon, before making landfall on China later that day. Afterward, Cempaka rapidly weakened as it moved inland, weakening into a tropical depression on July 21. The storm subsequently initiated a counterclockwise loop, moving westward across southern China, and turning southward and emergin ...

Tropical Storm Koguma
Tropical Storm Koguma was a weak tropical cyclone that made landfall in Vietnam, causing minor damage. The fourth named storm of the 2021 Pacific typhoon season, the system was first noted as an area of persistent convection on the South China Sea on June 10, with the JTWC assessing the system in its first advisory as a monsoon depression. Tracking west-northwestward, marginally conductive environmental conditions in the area allowed slight intensification while drifting towards Hainan Island. On the next day, the JMA upgraded the system to a tropical depression as it passed to the south of the territory before the agency upgraded the system to a tropical storm on June 12, being assigned the name ''Koguma''. The JTWC; however still treated the system as a tropical depression until 12:00 UTC that day. It continued to move northwest over the warm waters of the Gulf of Tonkin, eventually making landfall in Vietnam over Thanh Hóa by the end of the same day, rapidly weakening afterwar ...

Tropical Storm Choi-wan (2021)
Tropical Storm Choi-wan, known in the Philippines as Tropical Storm Dante, was a tropical storm which caused moderate flooding and damage in the Philippines and also affected Taiwan. The third named storm of the 2021 Pacific typhoon season, Choi-wan originated from an area of low pressure, located south-southeast of Guam near a brewing system. Fueled by an environment favorable for tropical cyclogenesis, it developed into a tropical depression, two days later as it moved westward. At 00:00 UTC on May 31, the system strengthened to a tropical storm and was named ''Choi-wan'' by the JMA. Although the storm was still located in the conductive conditions off the Philippine Sea while moving northwestward, a tropical upper tropospheric trough to the northeast halted the system's intensification, with Choi-wan's convection displaced to the south of its circulation on satellite imagery. Heavy rains caused floods across a majority of Mindanao and Visayas; 11 fatalities were reported and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Weather Bureau
The Central Weather Bureau (CWB; ) is the government meteorological research and forecasting institution of the Republic of China (Taiwan). In addition to meteorology, the Central Weather Bureau also makes astronomical observations, reports on sea conditions, and conducts research into seismology and provides earthquake reports. The Central Weather Bureau is headquartered in Taipei City and is administered under the Ministry of Transportation and Communications. History While Taiwan was under Japanese rule, the government set up five weather monitoring stations on the island, located in Taipei, Taichung, Tainan, Hengchun, and Penghu. On 19 December 1897, the Governor-General moved the headquarters to the present location occupied by the eventual successor agency of the Japanese "Taipei Observatory": the Central Weather Bureau. In 1945 when the Kuomintang took control of Taiwan the various stations set up by the Japanese were incorporated into the new Taiwan Provincial Weather In ...

Typhoon
A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. This region is referred to as the Northwestern Pacific Basin, and is the most active tropical cyclone basin on Earth, accounting for almost one-third of the world's annual tropical cyclones. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E). The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centers for the northwest Pacific in Hawaii (the Joint Typhoon Warning Center), the Philippines, and Hong Kong. Although the RSMC names each system, the main name list itself is coordinated among 18 countries that have territories threatened by typhoons each year. Within most of the northwestern Pacific, there are no official typhoon seasons as tropical cyclones form thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joint Typhoon Warning Center
The Joint typhoon Warning Center (JTWC) is a joint United States Navy – United States Air Force command in Pearl Harbor, Hawaii. The JTWC is responsible for the issuing of tropical cyclone warnings in the North-West Pacific Ocean, South Pacific Ocean, and Indian Ocean for all branches of the U.S. Department of Defense and other U.S. government agencies.
