Typhoon Gordon (1982)
The 1982 Pacific typhoon season was an average season in terms of total tropical storms, though it featured a very high amount of typhoons. It ran year-round in 1982, but most tropical cyclones formed between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. A total of 37 tropical depressions formed this year, of which 25 became tropical storms and were assigned a name by the Joint Typhoon Warning Center. Additionally, tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names. This year, a total of 23 storms were named this way. Of the 25 named storms, 19 storms reached typhoon intensity, of which only 2 reached super typhoon strength. During this season, the first tropical cyclone formed on Marc ...

Typhoon Ken (1982)
Typhoon Ken, known in the Philippines as Typhoon Tering, was the fourth typhoon to strike Japan during the 1982 Pacific typhoon season. Forming along the western end of the monsoon trough in the Philippine Sea, the system had organized into a tropical depression on September 16, and by that night a tropical storm. As a compact system, rapid intensification continued, with Ken becoming a typhoon on the evening of September 17 and a major typhoon on September 18. The cyclone up to this point had a history of progressing slowly west-northwest, but Ken eventually stalled on September 20 and became a larger cyclone. As a mid-latitude trough to its north deepened, Ken took off to the northeast towards Okinawa. Ken made landfall upon Shikoku early on September 25, and moved onward into the Sea of Japan where it evolved into an extratropical cyclone. Five people were killed while 18 others were hurt. A total of 114 mudslides were reported, resulted in ov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South China Sea
The South China Sea is a marginal sea of the Western Pacific Ocean. It is bounded in the north by South China, in the west by the Indochinese Peninsula, in the east by the islands of Taiwan island, Taiwan and northwestern Philippines (mainly Luzon, Mindoro and Palawan Island, Palawan), and in the south by Borneo, eastern Sumatra and the Bangka Belitung Islands, encompassing an area of around . It communicates with the East China Sea via the Taiwan Strait, the Philippine Sea via the Luzon Strait, the Sulu Sea via the straits around Palawan, the Java Sea via the Karimata Strait, Karimata and Bangka Straits and directly with Gulf of Thailand. The Gulf of Tonkin is part of the South China Sea. $3.4 trillion of the world's $16 trillion Maritime transport, maritime shipping passed through South China Sea in 2016. Oil and natural gas reserves have been found in the area. The Western Central Pacific accounted for 14% of world's commercial fishing in 2010. The South China Sea Islands, ...

Mindanao ( ) is the List of islands of the Philippines, second-largest island in the Philippines, after Luzon, and List of islands by population, seventh-most populous island in the world. Located in the southern region of the archipelago, the island is part of an island group of the same name that also includes its adjacent islands, notably the Sulu Archipelago. According to the 2020 census, Mindanao had a population of 26,252,442, while the entire island group had an estimated population of 27,021,036. Mindanao is divided into six administrative regions: the Zamboanga Peninsula, Northern Mindanao, the Caraga region, the Davao Region, Davao region, Soccsksargen, and the autonomous region of Bangsamoro. According to the 2020 census, Davao City is the most populous city on the island, with 1,776,949 people, followed by Zamboanga City (pop. 977,234), Cagayan de Oro (pop. 728,402), General Santos (pop. 697,315), Butuan (pop. 372,910), Iligan (pop. 363,115) and Cotabato City (pop. ...

Eye (cyclone)
The eye is a region of mostly calm weather at the center of a tropical cyclone. The eye of a storm is a roughly circular area, typically in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather and highest winds of the cyclone occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is where the barometer reading is lowest. Structure A typical tropi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maximum Sustained Winds
The maximum sustained wind associated with a tropical cyclone is a common indicator of the intensity of the storm. Within a mature tropical cyclone, it is found within the eyewall at a certain distance from the center, known as the radius of maximum wind, or RMW. Unlike gusts, the value of these winds are determined via their sampling and averaging the sampled results over a period of time. Wind measuring has been standardized globally to reflect the winds at above mean sea level, and the maximum sustained wind represents the highest average wind over either a one-minute (US) or ten-minute time span (see the definition, below), anywhere within the tropical cyclone. Surface winds are highly variable due to friction between the atmosphere and the Earth's surface, as well as near hills and mountains over land. Over the ocean, satellite imagery is often used to estimate the maximum sustained winds within a tropical cyclone. Land, ship, aircraft reconnaissance observations, an ...

Ridge (meteorology)
In meteorology a ridge or barometric ridge is an elongated area of relatively high atmospheric pressure compared to the surrounding environment, without being a closed circulation. It is associated with an area of maximum anticyclonic curvature of wind flow. The ridge originates in the center of an anticyclone and sandwiched between two low-pressure areas, and the locus of the maximum curvature is called the ''ridge line''. This phenomenon is the opposite of a trough. Description Ridges can be represented in two ways: * On surface weather maps, the pressure isobars form contours where the maximum pressure is found along the axis of the ridge. * In upper-air maps, geopotential height isohypses form similar contours where the maximum defines the ridge. Related weather Given the direction of the winds around an anticyclonic circulation and the fact that weather systems move from west to east: *ahead of an upper-ridge, the airflow that comes from the polar regions and bri ...

Regional Specialized Meteorological Center
A Regional Specialized Meteorological Centre (RSMC) is responsible for the distribution of information, advisories, and warnings regarding the specific program they have a part of, agreed by consensus at the World Meteorological Organization as part of the World Weather Watch. Environmental emergency response programme As a result of the poor communications between countries following the Chernobyl disaster in the Spring of 1986, the World Meteorological Organization (WMO) was requested by the International Atomic Energy Agency (IAEA) and other international organizations to arrange for early warning messages about nuclear accidents to be transmitted over the Global Telecommunications System (GTS). In addition some WMO member countries that lacked extensive forecasting capability requested that specialized pollutant transport and dispersion forecasts be provided during these emergencies. As a result, during 1989 Meteo-France (MF), Environment Canada (EC) and the United Kingdom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
