Typhoon Maemi
Typhoon Maemi () or (), known in the Philippines as Super Typhoon Pogi, was the most powerful typhoon to strike South Korea since record-keeping began in the country in 1904. Maemi formed on 4 September 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 . 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 typhoon became extratropic ...

Busan
Busan (), officially Busan Metropolitan City, is South Korea's second list of cities in South Korea by population, most populous city after Seoul, with a population of over 3.3 million as of 2024.

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] |
Wind Shear
Wind shear (; also written 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

South Korean Won
The South Korean won (symbol: ₩; code: KRW; ) 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, which was derived from the Spanish-American silver dollar. It is derived from the hanja (, ), meaning "round", which describes the shape of the silver dollar. The won was subdivided into 100 (), itself a cognate of the East Asian 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 all derived from the Spanish-American silver dollar, a coin widely used for international trade bet ...

Typhoon Sarah (1959)
Typhoon Sarah, known as the Miyakojima Typhoon in Japan, was a destructive typhoon which was one of the strongest storms on record to strike South Korea and Russia. 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 Japane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Dollar
The United States dollar (Currency symbol, symbol: Dollar sign, $; ISO 4217, currency code: USD) is the official currency of the United States and International use of the U.S. dollar, several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish dollar, Spanish silver dollar, divided it into 100 cent (currency), cents, and authorized the Mint (facility), 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 U.S. dollar was originally defined under a bimetallism, bimetallic standard of (0.7734375 troy ounces) fine silver or, from Coinage Act of 1834, 1834, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equivalence to gold was revised to $35 per troy ounce. In 1971 all links to gold were repealed. The U.S. dollar became an important intern ... [...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 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 pre-war value as Japan faced a debt crisis and hyperinflation. Under the Bretton Woods system, the yen was pegged to the US dollar alongside other major currencies. After this system was abandoned in 1971 with the Nixon shock, Nixon Shock, the short-lived Smithsonian Agreement temporarily reinstat ...
