Typhoon Kong-rey (2024)
Typhoon Kong-rey, known in the Philippines as Super Typhoon Leon, was a powerful tropical cyclone that impacted Taiwan and the Philippines before later affecting East China, South Korea, and Japan in late October and early November 2024. Kong-rey was the first typhoon in Taiwan's history to make landfall after mid-October and the largest storm to strike since Typhoon Herb in 1996. Additionally, it was the second tropical cyclone in a series to impact the Philippines, following Tropical Storm Trami (2024), Tropical Storm Trami a few days earlier, and preceding Typhoons Typhoon Yinxing, Yinxing, Typhoon Toraji (2024), Toraji, Typhoon Usagi (2024), Usagi, and Typhoon Man-yi (2024), Man-yi which would impact a few days later. The twenty-first named storm and the third List of super typhoons, super typhoon of the 2024 Pacific typhoon season, annual typhoon season, Kong-rey Tropical cyclogenesis, developed from a weak exposed low-level circulation located west-northwest of Guam.

Cagayan Valley
Cagayan Valley ( ilo, Tanap ti Cagayan; fil, Lambak ng Cagayan), is an administrative region in the Philippines, located in the northeastern section of Luzon Island. It is composed of five Philippine provinces: Batanes, Cagayan, Isabela, Nueva Vizcaya, and Quirino. The region hosts four chartered cities of Cauayan, Ilagan, Santiago, and Tuguegarao. Most of the land area is situated on the valley between the Cordilleras and the Sierra Madre mountain ranges. The eponymous Cagayan River, the country's largest and longest, runs through the region and flows from the Caraballo Mountains and ends at Aparri. Cagayan Valley is the second largest Philippine administrative region by land area. According to a literacy survey in 2013, 97.2% of Cagayan Valley's citizens (ages 10 to 64) are functionally literate, which is the highest out of the seventeen regions of the Philippines. History Archaeology indicates that Cagayan has been inhabited for half a million years, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Named Storm
Tropical cyclones and subtropical cyclones are named by various warning centers to simplify communication between forecasters and the general public regarding forecasts, watches and warnings. The names are intended to reduce confusion in the event of concurrent storms in the same basin. Once storms develop sustained wind speeds of more than , names are generally assigned to them from predetermined lists, depending on the basin in which they originate. Some tropical depressions are named in the Western Pacific; while tropical cyclones must contain a significant amount of gale-force winds before they are named in the Southern Hemisphere. Before it became standard practice to give personal (first) names to tropical cyclones, they were named after places, objects, or the saints' feast days on which they occurred. Credit for the first usage of personal names for weather systems is generally given to Queensland Government Meteorologist Clement Wragge, who named systems between 1 ...

Extratropical Transition
Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to severe gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as large scale (synoptic) low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone. Terminology The term " cyclone" applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor ''extratropical'' signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude. They are ter ...

Weather Front
A weather front is a boundary separating air masses for which several characteristics differ, such as air density, wind, temperature, and humidity. Disturbed and unstable weather due to these differences often arises along the boundary. For instance, cold fronts can bring bands of thunderstorms and cumulonimbus precipitation or be preceded by squall lines, while warm fronts are usually preceded by stratiform precipitation and fog. In summer, subtler humidity gradients are known as dry lines can trigger severe weather. Some fronts produce no precipitation and little cloudiness, although there is invariably always a wind shift. Cold fronts generally move from west to east, whereas warm fronts move poleward, although any direction is possible. Occluded fronts are a hybrid merge of the two, and stationary fronts are stalled in their motion. Cold fronts and cold occlusions move faster than warm fronts and warm occlusions because the dense air behind them can lift as we ...

Chenggong, Taitung
Chenggong Township or Chengkung Township() is an urban township in Taitung County, Taiwan. It is a coastal town facing the Pacific Ocean. Chenggong Fish Harbor is just west of downtown. History Chenggong was originally an Amis settlement from which came the Hokkien name Moalaulau (). During Japanese rule, it was renamed to of Taitō Prefecture. After 1945, to avoid confusion with Singang Township of Chiayi County and to distinguish it from Tainan's Sinckan (now called Sinshih), it was changed to Chenggong, which commemorates the eponymous general Koxinga (Cheng Ch'eng-kung) who expelled the Dutch from Taiwan. Geography The township has 14,943 inhabitants and its total area is 144.9938 km². Climate Along with the most of the rest of Taitung County, Chenggong has a tropical monsoon climate.

Orchid Island
Orchid Island, also known by other names, is a volcanic island off the southeastern coast of Taiwan Island. The island is part of Taiwan. It is separated from the Batanes of the Philippines by the Bashi Channel of the Luzon Strait. It is governed as of Taitung County, Taiwan, which also includes the nearby . Names Orchid Island is known by the Tao people indigenous to the island as Pongso no Tao ("island of human beings"). It was also known by the Tao as Ma'ataw ("floating in the sea") or Irala ("facing the mountain"); the latter being contrasted with the Tao name for the Taiwanese mainland - "Ilaod" ("toward the sea"). In the 17th century, it appeared on Japanese maps as "Tabako", a name borrowed into French and English as "Tabaco". It is still known by Filipinos as , a name also formerly used in English.. Lesser Orchid Island was similarly known as "Little Botel-Tobago". "Orchid Island" is a calque of the Chinese name, written in traditional characters, although ...

Batanes
Batanes, officially the Province of Batanes ( ivv, Provinsiya nu Batanes; Ilocano: ''Probinsia ti Batanes''; fil, Lalawigan ng Batanes, ), is an archipelagic province in the Philippines, administratively part of the Cagayan Valley region. It is the northernmost province in the country, and also the smallest, both in population and land area. The capital is Basco, located on the island of Batan. The island group is located approximately north of the Luzon mainland and about south of Taiwan ( Pingtung County), separated from the Babuyan Islands of Cagayan Province by the Balintang Channel, and from Taiwan by the Bashi Channel. The entire province is listed in the UNESCO tentative list for inscription in the World Heritage List. The government has been finalizing the site's inscription, establishing museums and conservation programs since 2001. Seven intangible heritage elements of the Ivatan have been set by the Philippine government in its initial inventory in 2012. The ...

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 atmospheri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eyewall Replacement Cycle
In meteorology, eyewall replacement cycles, also called concentric eyewall cycles, naturally occur in intense tropical cyclones, generally with winds greater than , or major hurricanes ( Category 3 or above). When tropical cyclones reach this intensity, and the eyewall contracts or is already sufficiently small, some of the outer rainbands may strengthen and organize into a ring of thunderstorms—a new, outer eyewall—that slowly moves inward and robs the original, inner eyewall of its needed moisture and angular momentum. Since the strongest winds are in a tropical cyclone's eyewall, the storm usually weakens during this phase, as the inner wall is "choked" by the outer wall. Eventually the outer eyewall replaces the inner one completely, and the storm may re-intensify. The discovery of this process was partially responsible for the end of the U.S. government's hurricane modification experiment Project Stormfury. This project set out to seed clouds outside the eyewall, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Pressure
Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as , which is equivalent to 1013.25 millibars, 760 mm Hg, 29.9212 inchesHg, or 14.696 psi.International Civil Aviation Organization. ''Manual of the ICAO Standard Atmosphere'', Doc 7488-CD, Third Edition, 1993. . The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure decreases with increasing elevation. Because the atmosphere is thin relative to the Earth's radius—especially the dense atmospheric layer at low altitudes—the E ...

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 ...

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. Their warnings are intended for the protection of primarily military ships and aircraft as well as military installations jointly operated with other countries around the world. Its U.S. Navy components are aligned with the Naval Meteorology and Oceanography Command. History The origins of the Joint Typhoon Warning Center (JTWC) can be traced back to June 1945, when the Fleet Weather Center/Typhoon Tracking Center was established on the island of Guam, after multiple typhoons, including Typhoon Cobra of December 1944 and Typhoon Connie in June 1945, had caused a significant loss of men and ships. At this time the center ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
