Typhoon Maemi
Typhoon Maemi () or (), known in the Philippines as Typhoon Pogi, was the most powerful typhoon to strike South Korea since record-keeping began in the country in 1904. Maemi formed on September 4, 2003 from a disturbance in a monsoon trough in the western Pacific Ocean. It slowly intensified into Tropical Storm Maemi while moving northwestward, becoming a typhoon on September 8. That day, favorable conditions facilitated more rapid strengthening; the storm developed a well-defined eye and reached peak maximum sustained winds of 195 km/h (120 mph). While near peak intensity, Maemi decelerated and began turning to the north-northeast. Soon after, the eyewall passed over the Japanese island of Miyako-jima on September 10 and produced an air pressure reading of , the fourth-lowest recorded in the nation. Due to warm waters, Maemi was able to maintain much of its intensity before it made landfall just west of Busan, South Korea, on September 12. The typh ...

Busan
Busan (), officially known as is South Korea's most populous city after Seoul, with a population of over 3.4 million inhabitants. Formerly romanized as Pusan, it is the economic, cultural and educational center of southeastern South Korea, with its port being Korea's busiest and the sixth-busiest in the world. The surrounding "Southeastern Maritime Industrial Region" (including Ulsan, South Gyeongsang, Daegu, and some of North Gyeongsang and South Jeolla) is South Korea's largest industrial area. The large volumes of port traffic and urban population in excess of 1 million make Busan a Large-Port metropolis using the Southampton System of Port-City classification . Busan is divided into 15 major administrative districts and a single county, together housing a population of approximately 3.6 million. The full metropolitan area, the Southeastern Maritime Industrial Region, has a population of approximately 8 million. The most densely built-up areas of the city are situated in ...

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 ...

Wind Shear
Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on the control of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convection (meteorology)
Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes. Overview There are a few general archetypes of atmospheric instability that are used to explain convection (or lack thereof). A necessary (but not sufficient) condition for convection is that the environmental lapse rate (the rate of decrease of temperature with height) is steeper than the lapse rate experienced by a rising parcel of air. When this condition is met, upward-displaced air parcels can become buoyant an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

South Korean Won
The Korean Republic won, unofficially the South Korean won ( Symbol: ₩; Code: KRW; Korean: 대한민국 원) is the official currency of South Korea. A single won is divided into 100 jeon, the monetary subunit. The jeon is no longer used for everyday transactions, and it appears only in foreign exchange rates. The currency is issued by the Bank of Korea, based in the capital city of Seoul. Etymology The old "won" was a cognate of the Chinese yuan and Japanese yen, which were both derived from the Spanish-American silver dollar. It is derived from the hanja (, ''won''), meaning "round", which describes the shape of the silver dollar. The won was subdivided into 100 ''jeon'' (), itself a cognate of the Chinese unit of weight mace and synonymous with money in general. The current won (1962 to present) is written in hangul only and does not officially have any hanja associated with it. First South Korean won History The Korean won, Chinese yuan and Japanese yen were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhoon Sarah (1959)
Typhoon Sarah, as known as the Miyakojima Typhoon in Japan was among the deadliest typhoons on record in the western Pacific Ocean, killing around 2,000 people. It formed during the peak of the busy 1959 Pacific typhoon season near Guam, and moved generally to the west-northwest. Continued observations from the hurricane hunters allowed the Joint Typhoon Warning Center (JTWC) to track Sarah from its origins to its peak as a powerful typhoon, with maximum sustained winds estimated at on September 15. Shortly thereafter, the typhoon struck the small Japanese island of Miyako-jima, where the barometric pressure fell to , the second-lowest on record for the country. Sarah turned to the north and northeast, weakening from its peak intensity. On September 17, the typhoon made landfall just west of Busan, South Korea with winds of , the nation's strongest landfall at the time and only to be surpassed by Typhoon Maemi in 2003. Sarah later became extratropical over the Japan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jeju Province
Jeju Province, officially Jeju Special Self-Governing Province, is one of the nine provinces of South Korea. The province comprises Jeju Island (; ), formerly transliterated as Cheju or Cheju Do, the country's largest island. It was previously known as Quelpart to Europeans and during the Japanese occupation of Korea, Japanese occupation as Saishū. The island lies in the Korea Strait, southwest of South Jeolla Province, of which it was a part before it became a separate province in 1946. Its capital is Jeju City and it is home to South Korea, South Korea's tallest mountain, Hallasan. History Early history According to the legend, three demigods emerged from Samseong mythology, Samseong, which is said to have been on the northern slopes of Halla Mountain, Mt. Halla and became the progenitors of the Jeju people, who founded the Kingdom of Tamna. It has also been claimed that three brothers, including Ko-hu, who were the 15th descendants of Koulla, one of the progenitors of the Jej ...

United States Dollar
The United States dollar ( symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank. The U.S. dollar was originally defined under a bimetallic standard of (0.7735 troy ounces) fine silver or, from 1837, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Yen
The is the official currency of Japan. It is the third-most traded currency in the foreign exchange market, after the United States dollar (US$) and the euro. It is also widely used as a third reserve currency after the US dollar and the euro. The New Currency Act of 1871 introduced Japan's modern currency system, with the yen defined as of gold, or of silver, and divided decimally into 100 ''sen'' or 1,000 ''rin''. The yen replaced the previous Tokugawa coinage as well as the various ''hansatsu'' paper currencies issued by feudal ''han'' (fiefs). The Bank of Japan was founded in 1882 and given a monopoly on controlling the money supply. Following World War II, the yen lost much of its prewar value. To stabilize the Japanese economy, the exchange rate of the yen was fixed at ¥360 per US$ as part of the Bretton Woods system. When that system was abandoned in 1971, the yen became undervalued and was allowed to float. The yen had appreciated to a peak of ¥271 per US$ ...
