Tropical Storm Zita
Severe Tropical Storm Zita, known in the Philippines as Tropical Storm Luming, was a short-lived tropical cyclone that killed seven people throughout southern China in August 1997. Originating from a tropical disturbance over the South China Sea on August 19, Zita tracked westward as it quickly strengthened within a region of light wind shear, attaining winds of as it made landfall along the Leizhou Peninsula early on August 22. Maintaining this intensity, the storm made a second landfall in northern Vietnam later that day before rapidly weakening over land. The remnants of Zita were last noted over extreme northwestern Vietnam on August 24. Although a relatively weak system, Tropical Storm Zita caused significant damage in Southern China. There, seven people were known to have been killed by the storm and damage reached $433 million (1997 United States dollar, USD). However, a report from Dartmouth College states that 345 people were killed by the storm. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leizhou Peninsula
The Leizhou Peninsula, alternately romanized as the Luichow Peninsula, is a peninsula in the southernmost part of Guangdong province in South China. History Qing naval forces were stationed at the Leizhou Peninsula. During the 19th century, the area was a hotbed of piracy, many pirates, such as Zheng Yi and Wu Shi Er, were based in the area. Geography The Leizhou Peninsula is the third largest peninsula in China with an area of c. located on the southwestern end of Zhanjiang, Guangdong with the Gulf of Tonkin to the west and the 30 km wide Qiongzhou Strait to the south, separating the peninsula from Hainan Island. Geologically, basalt terraces account for 43% of the peninsula's area. The rest is divided up between marine terraces (27%) and alluvial plains (17%). Leizhou Peninsula is dotted with a few dormant volcanoes, beaches, and low-lying diluvial plains. Leizhou has two separate volcanic fields: a Pleistocene–Holocene field at the norther ...

Tropical Cyclone Formation Alert
A Tropical Cyclone Formation Alert (TCFA) is a bulletin released by the U.S. Navy-operated Joint Typhoon Warning Center in Honolulu, Hawaii or the Fleet Weather Center in Norfolk, Virginia, warning of the possibility of a tropical cyclone forming from a tropical disturbance that has been monitored. Such alerts are generally always issued when it is fairly certain that a tropical cyclone will form and are not always released before cyclone genesis, particularly if the cyclone appears suddenly. The TCFA consists of several different checks that are performed by the on-duty meteorologist of the system and its surroundings. If the condition being checked is met, a certain number of points are given to the system. Parts of the TCFA Section 1 The first section of the TCFA contains information on the area of the alert as well as the estimated center of the circulation. The estimated maximum sustained winds are provided as well. Section 2 The second section generally contains more spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guangdong
Guangdong (, ), alternatively romanized as Canton or Kwangtung, is a coastal province in South China on the north shore of the South China Sea. The capital of the province is Guangzhou.

Gulf Of Tonkin
The Gulf of Tonkin is a gulf at the northwestern portion of the South China Sea, located off the coasts of Tonkin ( northern Vietnam) and South China. It has a total surface area of . It is defined in the west and northwest by the northern coastline of Vietnam down to the Hòn La Island, in the north by China's Guangxi Zhuang Autonomous Region, and to the east by the Leizhou Peninsula and Hainan Island. Etymology The name ''Tonkin'', written "" in Hán-Nôm characters and in the Vietnamese alphabet, means "eastern capital", and is the former toponym for Hanoi, the present capital of Vietnam. It should not to be confused with Tokyo, which is also written "" and also means "eastern capital". During the French colonial era, the northern region of today’s Vietnam was called ''Tonkin''.

Mbar
The bar is a metric unit of pressure, but not part of the International System of Units (SI). It is defined as exactly equal to 100,000 Pa (100 kPa), or slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar). By the barometric formula, 1 bar is roughly the atmospheric pressure on Earth at an altitude of 111 metres at 15 °C. The bar and the millibar were introduced by the Norwegian meteorologist Vilhelm Bjerknes, who was a founder of the modern practice of weather forecasting. The International System of Units, despite previously mentioning the bar, now omits any mention of it.. The bar has been legally recognised in countries of the European Union since 2004. British Standard BS 350:2004 ''Conversion Factors for Units''. The US National Institute of Standards and Technology (NIST) deprecates its use except for "limited use in meteorology" and lists it as one of several units that "must not be introd ...

Barometric 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 Organiz |
