2010 Pacific Typhoon Season
The 2010 Pacific typhoon season, with 14 named storms, was the least active Pacific typhoon season on record. Seven of them strengthened into typhoons while one reached super typhoon intensity. All of the 14 named storms developed west of 150°E. The season ran throughout 2010, though most tropical cyclones tend to develop between June and October. The season's first named storm, Omais, developed on March 24 while the season's last named storm, Chaba dissipated or became extratropical on October 30. During the season only three storms were notable. Typhoon Kompasu was the strongest storm to make landfall over in South Korea in 15 years. In September, Typhoon Fanapi struck Taiwan and China, causing heavy damage in the two countries. No storms made landfall in mainland Japan, only the second such occurrence since 1988. During October, Typhoon Megi reached its peak intensity with a minimum barometric pressure of 885 hPa, making it one of the most intense typhoons ever recor ...

Maximum Sustained Wind
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 ...

Convection (meteorology)
Atmospheric convection is the vertical transport of heat and moisture in the atmosphere. It occurs when warmer, less dense air rises, while cooler, denser air sinks. This process is driven by Air parcel, parcel-environment instability, meaning that a "parcel" of air is warmer and less dense than the surrounding environment at the same altitude. This difference in temperature and density (and sometimes humidity) causes the parcel to rise, a process known as buoyancy. This rising air, along with the compensating sinking air, leads to mixing, which in turn expands the height of the planetary boundary layer (PBL), the lowest part of the atmosphere directly influenced by the Earth's surface. This expansion contributes to increased Wind, winds, cumulus cloud development, and decreased surface Dew point, dew points (the temperature below which condensation occurs). Convection plays a crucial role in weather patterns, influencing cloud formation, wind, and the development of Thunderstor ...

Vorticity
In continuum mechanics, vorticity is a pseudovector (or axial vector) field that describes the local spinning motion of a continuum near some point (the tendency of something to rotate), as would be seen by an observer located at that point and traveling along with the flow. It is an important quantity in the dynamical theory of fluids and provides a convenient framework for understanding a variety of complex flow phenomena, such as the formation and motion of vortex rings. Mathematically, the vorticity \boldsymbol is the curl of the flow velocity \mathbf v: :\boldsymbol \equiv \nabla \times \mathbf v\,, where \nabla is the nabla operator. Conceptually, \boldsymbol could be determined by marking parts of a continuum in a small neighborhood of the point in question, and watching their ''relative'' displacements as they move along the flow. The vorticity \boldsymbol would be twice the mean angular velocity vector of those particles relative to their center of mass, orie ...

1998 Pacific Typhoon Season
The 1998 Pacific typhoon season was the least active List of Pacific typhoon seasons, Pacific typhoon season on record, until it was surpassed 2010 Pacific typhoon season, 12 years later. It was also the third-latest starting Pacific typhoon season on record. The season produced 16 tropical storms, 8 strengthening into typhoons. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line. Storms that form east of the date line and north of the equator are called hurricanes; see 1998 Pacific hurricane season. Tropical Storms formed in the entire west Pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chuuk State
Chuuk State (; also known as Truk) is one of the four states of the Federated States of Micronesia (FSM). It consists of several island groups: Nomoneas, Faichuk, Faichuuk, the Hall Islands, Namonuito Atoll (Magur Islands), Pattiw (Western Islands), and the Nomoi Islands, Mortlock Islands. Chuuk is by far the FSM's most populous state, with 50,000 inhabitants on . Chuuk Lagoon is where most people live. Weno island, in the lagoon, is Chuuk's state capital and the country's biggest city. It may Proposed Chuukese independence referendum, hold a referendum on independence in the near future, although this referendum has been repeatedly postponed. History Indigenous settlement Chuuk was first settled by Austronesian peoples, Austronesians, believed to be from the Lapita culture of Island Melanesia. Archaeological evidence indicates that islands of Fefan, Feefen and Wééné Islands had human settlements in the second and first century BCE. Later evidence indicates that widespread ...

Typhoon Chanthu (2010)
Typhoon Chanthu, known in the Philippines as Tropical Storm Caloy, was a weak typhoon that impacted southeastern China in the 2010 Pacific typhoon season. The storm formed on July 17, slowly moving to the Philippines, making direct landfall in Aurora. The storm later was later named respectively as Caloy and Chanthu. The storm later made its way to China, where the storm had its peak intensity. The storm later dissipated on July 23. As a result of the storm, there was heavy rainfall and flooding in the affected areas. In the Philippines, eight people died, with hundreds of stranded residents. In China, 9 people were killed, with a CNY 5.54 billion (US$817.7 million) loss. In Vietnam, 10 people died, with infrastructure damaged. Meteorological history Early on July 17, the JMA reported that a tropical depression had developed about 220 km (135 mi) to the northeast of Manila, Philippines. Later that day the JTWC reported that the depression had a small low level circulati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhoon Conson (2010)
Typhoon Conson (transliterated from Vietnamese Côn Sơn), known in the Philippines as Typhoon Basyang, was the second tropical cyclone during the 2010 Pacific typhoon season to impact the Philippines. Developing out of a tropical disturbance east of the Philippines on July 11, 2010, Conson quickly developed as it tracked nearly due west. Favorable environmental conditions, such as low wind shear and warm sea surface temperatures, allowed the system to intensify into a severe tropical storm by July 12. Around the same time, the JTWC assessed the storm to have been equivalent to a Category 1 hurricane. The following day, Conson struck Quezon, Quezon Province with winds of Wind speeds are listed by 10-minute standards unless otherwise noted. before weakening. After crossing the archipelago, the storm entered the South China Sea where it was able to re-strengthen. By July 16, Conson attained typhoon status as it neared the southern Chinese island of Hainan. After br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Weather Bureau
The Central Weather Administration (CWA; ) is the government meteorological research and forecasting institution of Taiwan (the Republic of China). In addition to meteorology, the Central Weather Administration also makes astronomical observations, reports on sea conditions, and conducts research into seismology and provides earthquake reports. The Central Weather Administration is headquartered in Taipei City and is administered under the Ministry of Transportation and Communications. History While Taiwan was under Japanese rule, the government set up five weather monitoring stations on the island, located in Taipei, Taichung, Tainan, Hengchun, and Penghu. On 19 December 1897, the Taipei Observatory moved to the location presently occupied by the Central Weather Administration. In 1945 when the Kuomintang took control of Taiwan the various stations set up by the Japanese were incorporated into the new Taiwan Provincial Weather Institution, under the Chief Executive of Taiwan Pr ...

Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system with a low-pressure area, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is called a hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean. A typhoon is the same thing which occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around the world, over half of which develop hurricane-force winds of or more. Tropical cyclones tropical cyclogenesis, typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water ...

Tropical Cyclone Seasonal Forecasting
Tropical cyclone seasonal forecasting is the process of predicting the number of tropical cyclones in one of the world's seven tropical cyclone basins during a particular tropical cyclone season. In the north Atlantic Ocean, one of the most widely publicized annual predictions comes from the Tropical Meteorology Project at Colorado State University. These reports are written by Philip J. Klotzbach and William M. Gray. Colorado State University's Tropical Meteorology Project Since 1984, Dr. William M. Gray and his associates at the Colorado State University have issued a seasonal forecast, that has aimed to predict the number of tropical storms and hurricanes that will develop within the Atlantic basin during the upcoming season amongst other factors. The forecasts were initially issued ahead of time for June and August. After the active 2005 Atlantic hurricane season, Dr Gray decided to allow Philip J. Klotzbach to take the primary responsibility for the project's seasonal, month ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
City University Of Hong Kong
The City University of Hong Kong (CityUHK) is a public research university in Kowloon Tong, Kowloon, Hong Kong. It was founded in 1984 as the City Polytechnic of Hong Kong and formally established as the City University of Hong Kong in 1994. The university currently has nine main schools offering courses in business, science, engineering, liberal arts and social sciences, law, and veterinary medicine, along with the Chow Yei Ching School of Graduate Studies, CityU Shenzhen Research Institute, and Hong Kong Institute for Advanced Study. History City University's origins lie in the calls for a "second polytechnic" in the years following the 1972 establishment of the Hong Kong Polytechnic. In 1982, Executive Council member Chung Sze-yuen spoke of a general consensus that "a second polytechnic of similar size to the first should be built as soon as possible."
