2001 Pacific Typhoon Season
The 2001 Pacific typhoon season was an average season with twenty-six named storms, sixteen typhoons and three super typhoons, with a near normal Accumulated Cyclone Energy (ACE) of 307.3 units. It ran year-round in 2001, with most tropical cyclones in the northwestern Pacific Ocean tending between May and November. The early season was relatively inactive, with the first named storm, Cimaron, not developing until May 9. Taiwan suffered the most destruction from typhoons this year, with Typhoons Toraji, Nari, and Lekima being responsible for nearly 300 deaths in that island alone, making it one of the deadliest typhoon seasons in recorded history in that island. In November, Typhoon Lingling impacted the Philippines, killing 171 people, making it one of the deadliest Philippine storms this century. The season ended with the formation of Tropical Storm Vamei during the last week of December. Vamei would be notable for becoming the lowest latitude tropical storm, at 1.4°N, ...

Equator
The equator is the circle of latitude that divides Earth into the Northern Hemisphere, Northern and Southern Hemisphere, Southern Hemispheres of Earth, hemispheres. It is an imaginary line located at 0 degrees latitude, about in circumference, halfway between the North Pole, North and South Pole, South poles. The term can also be used for any other celestial body that is roughly spherical. In three-dimensional space, spatial (3D) geometry, as applied in astronomy, the equator of a rotating spheroid (such as a planet) is the parallel (circle of latitude) at which latitude is defined to be 0°. It is an imaginary line on the spheroid, equidistant from its geographical pole, poles, dividing it into northern and southern hemispheres. In other words, it is the intersection of the spheroid with the plane (geometry), plane perpendicular to its axis of rotation and midway between its geographical poles. On and near the equator (on Earth), noontime sunlight appears almost directly o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Storm Durian (2001)
Severe Tropical Storm Durian was a deadly system that caused severe impacts in China and Vietnam in late-June and early-July 2001. The seventh tropical depression and third named storm of the 2001 Pacific typhoon season, the storm was first noted on June 29 and quickly intensified into a tropical storm and given the name Durian by the Japan Meteorological Agency (JMA). Durian continued northwestward before intensifying into a severe tropical storm as it approached the Chinese coast. On July 1 just before landfall, Durian peaked in intensity, with the JMA estimating 10-min winds of and the Joint Typhoon Warning Center (JTWC) estimating 1-min winds of . Durian made landfall on Zhanjiang at peak intensity, before quickly weakening over land and dissipating on July 3 over the mountains of Vietnam. In China, Durian caused 65 deaths and 4.5 billion yuan ($449 million) in damages, with thousands of houses being destroyed and 180 thousand hectares of farmland being damaged. In Northern Vi ...

Typhoon Chebi (2001)
Typhoon Chebi known in the Philippines as Typhoon Emong, was a powerful tropical cyclone that caused damage and deaths in five countries, the Philippines, Taiwan, China, South Korea, and Japan in late-June 2001. The fourth depression, second named storm, and first typhoon of the 2001 Pacific typhoon season, Chebi formed from an area of convection that developed into a tropical depression southeast of Palau. The depression quickly strengthened into Tropical Storm Chebi six hours later. Chebi continued to move westward, passing over cooler waters, which caused Chebi to weaken, but it still maintained tropical storm status as it entered the Luzon Strait on June 23. In the Luzon Strait, Chebi encountered favorable conditions and began to re-intensify. By June 23, Chebi had reached Category 1- equivalent typhoon status. The storm continued to strengthen overnight, and by June 24, Chebi had reached its peak intensity. A trough of low pressure to the north of Chebi caused the storm to ...

Sea-surface Temperatures
Sea surface temperature (or ocean surface temperature) is the temperature of ocean water close to the surface. The exact meaning of ''surface'' varies in the literature and in practice. It is usually between and below the sea surface. Sea surface temperatures greatly modify air masses in the Earth's atmosphere within a short distance of the shore. The thermohaline circulation has a major impact on average sea surface temperature throughout most of the world's oceans. Warm sea surface temperatures can develop and strengthen cyclones over the ocean. Tropical cyclones can also cause a cool wake. This is due to turbulent mixing of the upper of the ocean. Sea surface temperature changes during the day. This is like the air above it, but to a lesser degree. There is less variation in sea surface temperature on breezy days than on calm days. Coastal sea surface temperatures can cause offshore winds to generate upwelling, which can significantly cool or warm nearby landmasses, but ...

Hawaii
Hawaii ( ; ) is an island U.S. state, state of the United States, in the Pacific Ocean about southwest of the U.S. mainland. One of the two Non-contiguous United States, non-contiguous U.S. states (along with Alaska), it is the only state not on the North American mainland, the only state that is an archipelago, and the only state in the tropics. Hawaii consists of 137 volcanic islands that comprise almost the entire Hawaiian Islands, Hawaiian archipelago (the exception, which is outside the state, is Midway Atoll). Spanning , the state is Physical geography, physiographically and Ethnology, ethnologically part of the Polynesian subregion of Oceania. Hawaii's ocean coastline is consequently the List of U.S. states and territories by coastline, fourth-longest in the U.S., at about .

Pearl Harbor
Pearl Harbor is an American lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. It was often visited by the naval fleet of the United States, before it was acquired from the Hawaiian Kingdom by the U.S. with the signing of the Reciprocity Treaty of 1875. Much of the harbor and surrounding lands are now a United States Navy deep-water naval base. It is also the headquarters of the United States Pacific Fleet. The U.S. government first obtained exclusive use of the inlet and the right to maintain a repair and coaling station for ships here in 1887. The Attack on Pearl Harbor, surprise attack on the harbor by the Imperial Japanese Navy on December 7, 1941, led the United States to United States declaration of war on Japan, declare war on the Empire of Japan, marking the American entry into World War II, United States' entry into World War II. History Pearl Harbor was originally an extensive shallow embayment called ''Wai Momi'' (meaning 'Waters of Pearl') or ''Puuloa' ...

Atmospheric Pressure
Atmospheric pressure, also known as air pressure or 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 1,013.25 millibars, 760 mm Hg, 29.9212 inchesHg, or 14.696 psi.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 altitu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Dvorak Technique
The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared Weather satellite, satellite images. Within the Dvorak satellite strength estimate for tropical cyclones, there are several Pattern recognition, visual patterns that a cyclone may take on which define the upper and lower bounds on its intensity. The primary patterns used are curved rainband, band pattern (T1.0-T4.5), Wind shear#Effects on tropical cyclones, shear pattern (T1.5–T3.5), central dense overcast (CDO) pattern (T2.5–T5.0), central cold cover (CCC) pattern, banding eye pattern (T4.0–T4.5), and Eye (cyclone), eye pattern (T4.5–T8.0). Both the central dense overcast and embedded eye pattern use the size of the CDO. The CDO pattern intensities start at T2.5, equivalent to minimal trop ...

Tropical Cyclone Forecast Model
A tropical cyclone forecast model is a computer program that uses meteorology, meteorological data to weather forecasting, forecast aspects of the future state of tropical cyclones. There are three types of models: statistical, dynamical, or combined statistical-dynamic. Dynamical models utilize powerful supercomputers with sophisticated mathematical modeling software and meteorological data to numerical weather prediction, calculate future weather conditions. Statistical models forecast the evolution of a tropical cyclone in a simpler manner, by extrapolating from historical datasets, and thus can be run quickly on platforms such as personal computers. Statistical-dynamical models use aspects of both types of forecasting. Four primary types of forecasts exist for tropical cyclones: tropical cyclone track forecasting, track, intensity, storm surge, and tropical cyclone rainfall climatology, rainfall. Dynamical models were not developed until the 1970s and the 1980s, with e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
