Typhoon Nelson (1985)
Typhoon Nelson, known in the Philippines as Typhoon Ibiang, was the worst tropical cyclone to affect Southern China in 16 years. Typhoon Nelson, which developed on August 16, 1985, originated from an area of thunderstorm activity well east of the Philippines. It gradually intensified over the next several days while moving northwest. Nelson reached typhoon intensity early on August 20 and two days later, attained peak intensity before turning west. The cyclone brushed northern Taiwan early on August 23 after weakening slightly. Nelson then briefly restrengthened to peak intensity. During the afternoon of August 23, it made landfall in eastern China before dissipating on August 25. Nelson brought heavy rains to Taiwan. Approximately 900,000 families were left without power and 100,000 telephone lines lost service. More than 20,000 trees were uprooted. Across the country, five people were killed. Affecting a country already inundated by summer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1985 Pacific Typhoon Season
The 1985 Pacific typhoon season has no official bounds; it ran year-round in 1985, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. 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. A total of 29 tropical depressions formed this year in the Western Pacific, of which 28 became tropical storms. 17 storms reached typhoon intensity, of which one typhoon reached super typhoon strength. The strongest cyclone of the season, Dot, reached category 5 on the Saffir–Simpson scale to the east of the Phili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Circulation
Atmospheric circulation is the large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth. The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant. The smaller scale weather systems – mid-latitude depressions, or tropical convective cells – occur chaotically, and long-range weather predictions of those cannot be made beyond ten days in practice, or a month in theory (see chaos theory and the butterfly effect). The Earth's weather is a consequence of its illumination by the Sun and the laws of thermodynamics. The atmospheric circulation can be viewed as a heat engine driven by the Sun's energy and whose energy sink, ultimately, is the blackness of space. The work produced by that engine causes the motion of the masses of air, and in that process it redistributes the energy absorbed by the Earth's surface near ...

Tropical Cyclone Warnings And Watches
Tropical cyclone warnings and watches are alerts issued by national weather forecasting bodies to coastal areas threatened by the imminent approach of a tropical cyclone of tropical storm or hurricane intensity. They are notices to the local population and civil authorities to make appropriate preparation for the cyclone, including evacuation of vulnerable areas where necessary. It is important that interests throughout the area of an alert make preparations to protect life and property, and do not disregard it on the strength of the detailed forecast track. Western hemisphere New tropical cyclone position and forecast information is available at least every twelve hours in the Southern Hemisphere and at least every six hours in the Northern Hemisphere from Regional Specialized Meteorological Centers and Tropical Cyclone Warning Centers. In conjunction with the National Hurricane Center, the national meteorological and hydrological services of Central America, the northern Atlan ...

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 distance defined 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 the Earth's surface, 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 determines the value of the maximum sustained winds within a tropical cyclone. Land, ship, aircraft reconnaissance observations, and radar imagery can ...

Fuchou
Fuzhou (; , Fuzhounese: Hokchew, ''Hók-ciŭ''), alternately romanized as Foochow, is the capital and one of the largest cities in Fujian province, China. Along with the many counties of Ningde, those of Fuzhou are considered to constitute the Mindong (lit. Eastern Fujian) linguistic and cultural area. Fuzhou lies on the north (left) bank of the estuary of Fujian's largest river, the Min River. All along its northern border lies Ningde, and Ningde's Gutian County lies upriver. Its population was 7,115,370 inhabitants as of the 2010 census, of whom 4,408,076 inhabitants are urban representing around 61.95%, while rural population is at 2,707,294 representing around 38.05%. As of 31 December 2018, the total population was estimated at 7,740,000 whom 4,665,000 lived in the built-up (''or metro'') area made of 5 urban districts plus Minhou County. In 2015, Fuzhou was ranked as the 10th fastest growing metropolitan area in the world by Brookings Institution. Fuzhou is liste ...

Formosa Strait
The Taiwan Strait is a -wide strait separating the island of Taiwan and continental Asia. The strait is part of the South China Sea and connects to the East China Sea to the north. The narrowest part is wide. The Taiwan Strait is itself a subject of international dispute over its political status. As the People's Republic of China claims to enjoy "sovereignty, sovereign rights and jurisdiction over the Taiwan Strait" and regards the waterway as " internal territorial waters" instead of being international waters, this means that the Chinese government denies any foreign vessel having the freedom of navigation in the strait. This position has drawn strong objections from the United States, Australia, France and Taiwan. Names Former names of the Taiwan Strait include the or from a dated name for Taiwan; the or Fujian, from the Chinese province forming the strait's western shore; and the , a calque of the strait's name in Hokkien and Hakka.

Eye (cyclone)
The eye is a region of mostly calm weather at the center of tropical cyclones. 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 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 the location of the storm's minimum barometric pressure—where the atmospheric pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclone Scales
Tropical cyclones are ranked on one of five tropical cyclone intensity scales, according to their maximum sustained winds and which tropical cyclone basins they are located in. Only a few scales of classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but other scales also exist, such as accumulated cyclone energy, the Power Dissipation Index, the Integrated Kinetic Energy Index, and the Hurricane Severity Index. Tropical cyclones that develop in the Northern Hemisphere are unofficially classified by the warning centres on one of three intensity scales. Tropical cyclones or subtropical cyclones that exist within the North Atlantic Ocean or the North-eastern Pacific Ocean are classified as either tropical depressions or tropical storms. Should a system intensify further and become a hurricane, then it will be classified on the Saffir–Simpson hurricane wind scale, and is based on the estimated maximum sustained winds over a 1-minut ...
