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 was a slightly above average season in terms of named storms, though most storms were weak and short-lived. The season had 28 named storms, 15 typhoons and 1 super typhoon. It ran year-round, thus ending the two-season run which began in 1983 Pacific typhoon season, 1983 that only had tropical cyclones forming 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 57 tropical depressions formed this year, of which only 28 became tropical storms and were assigned a name by the Joint Typhoon Warning Center. This made the season well above average. Additionally, tropical depressions that enter or form in the Philippine area of responsibility were 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 17 storms w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Circulation
Atmospheric circulation is the large-scale movement of Atmosphere of Earth, 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 – middle latitudes, mid-latitude low-pressure area, 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 heat sink, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Atla ...

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 ...

Fuzhou is the capital of Fujian, China. The city lies between the Min River (Fujian), Min River estuary to the south and the city of Ningde to the north. Together, Fuzhou and Ningde make up the Eastern Min, Mindong linguistic and cultural region. Fuzhou's population was 8,291,268 as of the 2020 Chinese census. Like other prefecture-level city, prefecture-level cities in China, its administrative area contains both urban and rural areas: in 2020, 72.49% of inhabitants (6,010,242) were urban, while 27.51% (2,281,026) were rural. 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 five 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 listed as No. 20 in the China Integrated City Index 2016's total ranking, a study conducted by the National Development and Reform Commission. Fuzhou is also ...

Formosa Strait
The Taiwan Strait is a strait separating the island of Taiwan and the Asian continent. The strait is part of the South China Sea and connects to the East China Sea to the north. The narrowest part is wide. 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. Geography The Taiwan Strait is the body of water separating Fujian Province from Taiwan Island. The international agreement does not define the Taiwan Strait but places its waters within the South China Sea, whose northern limit runs from Cape Fugui (the northernmost point on Taiwan Island; Fukikaku) to Niushan Island to the southernmost point of Pingtan Island and thence westward along the parallel N. to the coast of Fujian Province. The draft for a new edition of the IHO's ''Limits of Oceans and Seas'' does precisely define the Taiwan Str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Miyako Islands
The (also Miyako Jima group) are a group of islands in Okinawa Prefecture, Japan, belonging to the Ryukyu Islands. They are situated between Okinawa Island and the Yaeyama Islands. In the early 1870s, the population of the islands was estimated to number approximately 10,000. Miyako Island has 55,914 people. A bridge connects Miyako Island to Ikema Island, which has 801 people. Tarama village has 1,214 people, between the two islands of Minna and Tarama. Important Bird Area The islands have been recognised as an Important Bird Area (IBA) by BirdLife International because they support populations of the resident Ryukyu green pigeons, as well as migrating whimbrels.

Yaeyama Islands
The Yaeyama Islands (八重山列島 ''Yaeyama-rettō'', also 八重山諸島 ''Yaeyama-shotō'', Yaeyama: ''Yaima'', Yonaguni: ''Daama'', Okinawan: ''Yeema'', Northern Ryukyuan: ''Yapema'') are an archipelago in the southwest of Okinawa Prefecture, Japan, and cover . The islands are located southwest of the Miyako Islands, part of the Ryukyu Islands archipelago. The Yaeyama Islands are the most remote part of Japan from the main islands and contain Japan's southernmost ( Hateruma) and westernmost (Yonaguni) inhabited islands. The city of Ishigaki serves as the political, cultural, and economic center of the Yaeyama Islands. On maps dating to the 1700s, the Yaeyama Group of Islands appears as the "Majico Sima Group", "Nambu-soto Islands", "Nambu Soto", and the "Taipin Islands". Name The name ''Yaeyama'' literally means "multilayered mountains", and is related to the native name ''Yaima'' in Yaeyama, which possibly comes from a reconstructed Proto-Ryukyuan form ''*jajama'' ...

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] |
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 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 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-minute period.
