From point of origin, the storm follows a northerly direction, only affecting small islands. [...] The Chinese applied the [Greek] concept to a rather different wind [...]", CS1 maint: multiple names: authors list (. [32], The list of names consists of entries from 17 Southeast and East Asian nations and the United States who have territories directly affected by typhoons. Overview. Like other basins, they are steered by the subtropical ridge towards the west or northwest, with some systems recurving near and east of Japan. | Photo by Gregory Lane. 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. [40] After Typhoon Morakot landed in Taiwan at midnight on August 8, 2009, almost the entire southern region of Taiwan (Chiayi County/Chiayi City, Tainan County/Tainan City (now merged as Tainan), Kaohsiung County/Kaohsiung City (now merged as Kaohsiung), and Pingtung County) and parts of Taitung County and Nantou County were flooded by record-breaking heavy rain. While the majority of storms form between June and November, a few storms do occur between December and May (although tropical cyclone formation is at a minimum during that time). [22] A ten-year average of satellite determined precipitation showed that at least 30 percent of the annual rainfall in the northern Philippines could be traced to tropical cyclones, while the southern islands receive less than 10 percent of their annual rainfall from tropical cyclones. [21] The most frequently impacted areas of the Philippines by tropical cyclones are northern and central Luzon and eastern Visayas. How will understanding of attitudes and predisposition enhance teaching? [23] The genesis and intensity of typhoons are also modulated by slow variation of the sea surface temperature and circulation features following a near-10-year frequency. One of the most recent busy seasons was 2013. On average, the northwestern Pacific features the most numerous and intense tropical cyclones globally. For instance, the typhoon names for this year … How long will the footprints on the moon last? What is the contribution of candido bartolome to gymnastics? Inter state form of sales tax income tax? A new name will be decided by the country whose name was retired. [10] Should the storm intensify further and reach sustained wind speeds of 48 knots (55 mph; 89 km/h) then it will be classified as a severe tropical storm. From 1699 appears "tuffoon", later "tiffoon", derived from Chinese with spelling influenced by the older Hindustani-derived forms. As the oscillation propagates from west to east, it leads to an eastward march in tropical cyclogenesis with time during that hemisphere's summer season. The 2004 Pacific typhoon season was the busiest for Okinawa since 1957. [13], There are six main requirements for tropical cyclogenesis: sufficiently warm sea surface temperatures, atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low pressure center, a pre-existing low level focus or disturbance, and low vertical wind shear. When all names on the list are used, it will start again from the left-top corner. Winds were over 150 mph or 240 kph. A parabolic recurving track. The Hindustani source word ṭūfān ("violent storm"; Perso-Arabic: طوفان‎, Devanagari: तूफ़ान)[8] comes from the Persian tūfān (Persian: توفان/طوفان‎) meaning "storm" which comes from the verb tūfīdan (Persian: توفیدن/طوفیدن‎), "to roar, to blow furiously". As a result, the JTWC's wind reports are higher than JMA's measurements, as the latter is based on a 10-minute averaging interval. Tropical cyclones form in any month of the year across the northwest Pacific Ocean, and concentrate around June and November in the northern Indian Ocean. Southwest Indian basin From Africa to about 100°E Beginning in late October/early November, reaching a double peak in activity-one in mid-January and one in mid-February to early March, and then ending in May. [15], In general, westerly wind increases associated with the Madden–Julian oscillation lead to increased tropical cyclogenesis in all tropical cyclone basins. [6] The Oxford English Dictionary[7] cites Hindustani ṭūfān and Chinese tai fung giving rise to several early forms in English. Activity falls off significantly in November, although Typhoon Haiyan, the strongest Philippine typhoon on record, was a November typhoon. Taiwan has received the wettest known typhoon on record for the northwest Pacific tropical cyclone basins. Regional Specialized Meteorological Center, National Meteorological and Hydrological Service, Philippine Atmospheric, Geophysical and Astronomical Services Administration, China tropical cyclone rainfall climatology, "Subject: F1) What regions around the globe have tropical cyclones and who is responsible for forecasting there? [36] Within Guangdong in southern China, during the past thousand years, the most active decades for typhoon strikes were the 1660s and 1670s.[37]. The first character is normally used to mean "pedestal" or "stand", but is actually a simplification of the older Chinese character 颱, which means "typhoon"; thus the word originally meant "typhoon wind". Typhoons, by definition, occur only in the Pacific, north of the equator and west of the international date line. When a typhoon causes damage in a country, the affected country can request for retiring the name in the next session of the ESCAP/WMO Typhoon Committee. Storms recurving affect eastern Philippines, eastern China, Taiwan, Korea, Japan, and the Russian Far East. Typhoon comes from Chinese 台风 [Táifēng], meaning: The Great Wind, The Big Wind and/or The Strong Wind. The rainfall in Pingtung County reached 2,327 millimeters (91.6 in),[41] breaking all rainfall records of any single place in Taiwan induced by a single typhoon,[42] and making the cyclone the wettest known typhoon. [8] The Persian term may originally have been influenced by the Greek word. [16] On average, twice per year twin tropical cyclones will form in the western Pacific Ocean, near the 5th parallel north and the 5th parallel south, along the same meridian, or line of longitude. [10] A tropical depression is upgraded to a tropical storm should its sustained wind speeds exceed 34 knots (39 mph; 63 km/h). [10], Since 2009 the Hong Kong Observatory has divided typhoons into three different classifications: typhoon, severe typhoon and super typhoon.
