Typhoon Doug (1994)
Typhoon Doug, known in the Philippines as Typhoon Ritang, was the only Category 5 typhoon in the 1994 Pacific typhoon season. The 13th storm and the second super typhoon of the season, it formed on the eastern end of a monsoon trough and developed into a tropical depression on August 2. It moved west and rapidly strengthened. Doug reached a peak of and winds of before brushing the coast of Taiwan. Doug made landfall near Shanghai, China as a weak tropical depression. Doug killed 26 people and caused $110 million (1994 USD) damage in Taiwan. Doug's effects reached Korea. Meteorological history A tropical disturbance west-northwest of Guam on the eastern end of a monsoon trough was first noted and developed into a tropical depression on August 2. It further intensified and became a tropical storm a few hours later, and the Joint Typhoon Warning Center (JTWC) assigned the system the name Doug. It moved westwards at and intensified, becoming a severe tropical storm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1994 Pacific Typhoon Season
The 1994 Pacific typhoon season was an extremely active season in the annual cycle of tropical cyclone formation in the Western North Pacific, with a total of 32 tropical storms, where 19 of them reached typhoon strength, during the course of the season, much like the Pacific hurricane season. The season had no official bounds and it ran year-round in 1994, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. Tropical storms that formed west of the date line were assigned a name by the Joint Typhoon Warning Center. The World Meteorological Organization-designated Regional Specialized Meteorological Centre for tropical cyclones for the region is the Japan Meteorological Agency. Tropical depressions that entered or formed in the Philippine area of responsibility were assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can result in some storms having two names. The season s ... [...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, 760mm Hg, 29.9212 inchesHg, or 14.696psi.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 Earth's gravi ...

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 ...

Korean Air Flight 2033
Korean Air Flight 2033 was a scheduled passenger flight from Seoul to Jeju, South Korea. On 10 August 1994, the Airbus A300 serving the route overran the runway on landing at Jeju International Airport in poor weather and burst into flames. All 160 people on board escaped without serious injury, but the aircraft was destroyed. History of the flight On the morning of 10 August, Korean Air Flight 2033 departed from Kimpo International Airport in Seoul for a one hour and ten minute domestic flight to Jeju. On board were 152 passengers and 8 crew. On arrival at Jeju, shortly after 11:00 local time, the weather was poor, with driving rain and winds of up to brought about by Typhoon Doug. The crew aborted their first approach. On their second attempt, the flaps were selected at a reduced setting (CONF3) due to the risk of windshear, which meant that the approach speed was higher than usual. The aircraft touched down more than halfway down the runway, and was unable to stop withi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airbus A300
The Airbus A300 is a wide-body airliner developed and manufactured by Airbus. In September 1967, aircraft manufacturers in the United Kingdom, France, and West Germany signed a memorandum of understanding to develop a large airliner. West Germany and France reached an agreement on 29 May 1969 after the British withdrew from the project on 10 April 1969. European collaborative aerospace manufacturer Airbus Industrie was formally created on 18 December 1970 to develop and produce it. The prototype first flew on 28 October 1972. The first twin-engine widebody airliner, the A300 typically seats 247 passengers in two classes over a range of 5,375 to 7,500 km (2,900 to 4,050 nmi). Initial variants are powered by General Electric CF6-50 or Pratt & Whitney JT9D turbofans and have a three-crew flight deck. The improved A300-600 has a two-crew cockpit and updated CF6-80C2 or PW4000 engines; it made its first flight on 8 July 1983 and entered service later that year. The A ...

Landslide
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated grade (slope), slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the She ...

Taipei
Taipei (), officially Taipei City, is the capital and a special municipality of the Republic of China (Taiwan). Located in Northern Taiwan, Taipei City is an enclave of the municipality of New Taipei City that sits about southwest of the northern port city of Keelung. Most of the city rests on the Taipei Basin, an ancient lakebed. The basin is bounded by the relatively narrow valleys of the Keelung and Xindian rivers, which join to form the Tamsui River along the city's western border. The city of Taipei is home to an estimated population of 2,646,204 (2019), forming the core part of the Taipei–Keelung metropolitan area, which includes the nearby cities of New Taipei and Keelung with a population of 7,047,559, the 40th most-populous urban area in the world—roughly one-third of Taiwanese citizens live in the metro district. The name "Taipei" can refer either to the whole metropolitan area or just the city itself. Taipei has been the seat of the ROC central government ...

Extratropical Cyclone
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 term ...

Landfall (meteorology)
Landfall is the event of a storm moving over land after being over water. More broadly, and in relation to human travel, it refers to 'the first land that is reached or seen at the end of a journey across the sea or through the air, or the fact of arriving there. Tropical cyclone A tropical cyclone is classified as making landfall when the center of the storm moves across the coast; in a relatively strong tropical cyclone, this is when the eye moves over land. This is where most of the damage occurs within a mature tropical cyclone, such as a typhoon or hurricane, as most of the damaging aspects of these systems are concentrated near the eyewall. Such effects include the peaking of the storm surge, the core of strong winds coming ashore, and heavy flooding rains. These coupled with high surf can cause major beach erosion. When a tropical cyclone makes landfall, the eye usually closes in upon itself due to negative environmental factors over land, such as friction with th ...

East China Sea
The East China Sea is an arm of the Western Pacific Ocean, located directly offshore from East China. It covers an area of roughly . The sea’s northern extension between mainland China and the Korean Peninsula is the Yellow Sea, separated by an imaginary line between the eastern tip of Qidong at the Yangtze River estuary and the southwestern tip of South Korea's Jeju Island. The East China Sea is bounded in the east and southeast by the middle portion of the first island chain off the eastern Eurasian continental mainland, including the Japanese island of Kyushu and the Ryukyu Islands, and in the south by the island of Taiwan. It connects with the Sea of Japan in the northeast through the Korea Strait, the South China Sea in the southwest via the Taiwan Strait, and the Philippine Sea in the southeast via gaps between the various Ryukyu Islands (e.g. Tokara Strait and Miyako Strait). Most of the East China Sea is shallow, with almost three-fourths of it being less than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
