Tropical Cyclones In 2011
During 2011, tropical cyclones formed within seven different tropical cyclone basins, located within various parts of the Atlantic, Pacific and Indian Oceans. During the year, a total of 131 tropical cyclones had formed this year to date. 71 tropical cyclones had been named by either a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC). Thirty-nine of these named systems eventually intensified into hurricane-equivalent tropical cyclones. The most active basin in the year was the Pacific typhoon, Western Pacific, which documented 21 named storms. Atlantic hurricane, North Atlantic basin documented 19 named storms, continuing the consecutive third-most active season trends from the previous year, due to the 2010–12 La Niña event. Conversely, the Pacific hurricane, Eastern Pacific basin featured slightly more activity than the 2010 Pacific hurricane season, previous season, with 11 named storms. The least active basin in the year was the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Depression 03 (2011)
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the Season, solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions of Earth, polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2010 Pacific Hurricane Season
The 2010 Pacific hurricane season was the least active Pacific hurricane season since modern records, tied with 1977. The season saw only eight named storms, alongside a record-breaking low of three hurricanes. However, of those three, two of them became major hurricanes, and one hurricane, Celia, reached Category 5 intensity on the Saffir-Simpson scale. Also had the second-fewest ACE units on record, as many of the storms were weak and short-lived. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, the formation of tropical cyclones is possible at any time of the year. Unlike the previous season, the first storm of the season, Agatha, formed during the month of May. Agatha developed on May 29 near the coast of Guatemala. In the second week of June, a sudden spre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone Bingiza
Tropical Cyclone Bingiza was the only named storm to make landfall in the inactive 2010–11 South-West Indian Ocean cyclone season. The second of three storms, Bingiza developed on 9 February to the northeast of Madagascar. For a few days it meandered generally southwestward, failing to intensify significantly. On 12 February, the storm began a steady westward track as environmental conditions became more favorable. In a 24‑hour period, Bingiza developed from a moderate tropical storm into an intense tropical cyclone with a well-defined eye. After attaining peak 10–minute sustained winds of , the cyclone moved ashore in northeastern Madagascar on 14 February and quickly weakened as it crossed the country. Bingiza emerged into the Mozambique Channel as a weak tropical disturbance, and it turned southward to move across western Madagascar. Bingiza attained tropical storm status before making its final landfall near Morondava, degenerating into a remnant low on 17 February ...

Cyclone Yasi
Severe Tropical Cyclone Yasi () was a powerful and destructive tropical cyclone that made landfall in northern Queensland, Australia in early 2011, causing major damage to the affected areas. Originating as a tropical low near Fiji on 26 January, the system intensified to tropical cyclone status during the evening of 30 January. Yasi deepened rapidly over the next 24 hours, and was classified as a Category 3 cyclone at about 5 PM AEST (07:00 UTC) on 31 January 2011. Late on 1 February, the cyclone strengthened to a Category 4 system; then, early on 2 February, the cyclone intensified into a Category 5 Severe Tropical Cyclone. The system had a well-defined eye and continued to track west-southwestward, maintaining a central pressure of 930 hPa (27 inHg) and a Dvorak intensity of T6.5 into the evening. At about 12:00 AM AEST (14:00 UTC) on 3 February, Yasi crossed the Australian coastline as a Category 5 severe tropical cyclone near Mission Beach, with estimated maximum 3 ...

Cyclone Wilma
Severe Tropical Cyclone Wilma was a powerful tropical cyclone that affected the Samoan Islands, Tonga and New Zealand. Forming out of a trough of low pressure on 19 January 2011 to the northwest of Fiji, Cyclone Wilma initially tracked eastward towards the Samoan Islands. On 22 January, the system took a sharp southward turn, bringing its centre directly over American Samoa the following day. After turning towards the southwest and accelerating, Wilma steadily intensified into a severe tropical cyclone before striking Tonga. The storm reached its peak intensity on 26 January as a Category 4 cyclone with winds of 185 km/h (115 mph) and a barometric pressure of 930 mbar (hPa; 27.46 inHg). Gradually re-curving towards the southeast, Wilma weakened quickly as it moved over cooler sea surface temperatures; by 28 January, it was downgraded to a tropical cyclone. Later that day, the storm brushed the North Island of New Zealand before transitioning into an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone Vania
Tropical Cyclone Vania (RSMC Nadi designation 03F, JTWC designation 05P) was the third depression and first tropical cyclone of the 2010–11 South Pacific cyclone season. Meteorological history During January 5, 2011, the Fiji Meteorological Service's Regional Specialised Meteorological Centre in Nadi, Fiji reported that Tropical Disturbance 03F, had developed about to the northeast of Nadi. Over the next few days the disturbance gradually developed further before RSMC Nadi classified it as a tropical depression early on January 9. On January 11, the Joint Typhoon Warning Center initiated warnings on the system and monitored it as Tropical Cyclone 05P. On the Next day, RSMC Nadi upgraded the depression into a Category 1 tropical cyclone and named it "Vania". Later that day, RSMC Nadi reported that Vania had intensified into a Category 2 tropical cyclone. Early the next day, RSMC Nadi upgraded Vania into a Category 3 severe tropical cyclone. Later that day, RSMC Nadi reported t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Severe Tropical Storm Washi
Severe Tropical Storm Washi, known in the Philippines as Tropical Storm Sendong, was a late-season tropical cyclone that caused around 1,200 to 1,500 deaths and catastrophic damage in the Philippines in late 2011. Washi made landfall over Mindanao, a major region in the Philippines, on December 16. Washi weakened slightly after passing Mindanao, but regained strength in the Sulu Sea, and made landfall again over Palawan on December 17. Meteorological history On December 12, the Joint Typhoon Warning Center (JTWC) noted that a developing area of low pressure had persisted about 945 km (585 mi) south-southeast of Guam. Situated along the southern edge of a subtropical ridge, the system tracked steadily westward towards the Philippines. Located within a region of good diffluence and moderate wind shear, deep convection was able to maintain itself over the circulation. Development of banding features and improvement of outflow indicated strengthening was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Irene
Hurricane Irene was a large and destructive tropical cyclone which affected much of the Caribbean and East Coast of the United States during late August 2011. The ninth named storm, first hurricane, and first major hurricane of the 2011 Atlantic hurricane season, Irene originated from a well-defined Atlantic tropical wave that began showing signs of organization east of the Lesser Antilles. Due to development of atmospheric convection and a closed center of circulation, the system was designated as Tropical Storm Irene on August 20, 2011. After intensifying, Irene made landfall in St. Croix as a strong tropical storm later that day. Early on August 21, the storm made a second landfall in Puerto Rico. While crossing the island, Irene strengthened into a Category 1 hurricane. The storm paralleled offshore of Hispaniola, continuing to slowly intensify in the process. Shortly before making four landfalls in the Bahamas, Irene peaked as a Category 3 hurricane. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 introduced ...

South Pacific Cyclone
Traditionally, areas of tropical cyclone formation are divided into seven basins. These include the north Atlantic Ocean, the eastern and western parts of the northern Pacific Ocean, the southwestern Pacific, the southwestern and southeastern Indian Oceans, and the northern Indian Ocean (Arabian Sea and Bay of Bengal). The western Pacific is the most active and the north Indian the least active. An average of 86 tropical cyclones of tropical storm intensity form annually worldwide, with 47 reaching hurricane/typhoon strength, and 20 becoming intense tropical cyclones, super typhoons, or major hurricanes (at least of Category 3 intensity). __TOC__ Overview Northern Hemisphere North Atlantic Ocean This region includes the North Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico. Tropical cyclone formation here varies widely from year to year, ranging from one to over twenty-five per year. Most Atlantic tropical storms and hurricanes form between June 1 and Novem ...

Australian Region Cyclone
An Australian region tropical cyclone is a non-frontal, low-pressure system that has developed within an environment of warm sea surface temperatures and little vertical wind shear aloft in either the Southern Indian Ocean or the South Pacific Ocean. Within the Southern Hemisphere there are officially three areas where tropical cyclones develop on a regular basis: the South-West Indian Ocean between Africa and 90°E, the Australian region between 90°E and 160°E, and the South Pacific basin between 160°E and 120°W. The Australian region between 90°E and 160°E is officially monitored by the Australian Bureau of Meteorology, the Indonesian Meteorology, Climatology, and Geophysical Agency, and the Papua New Guinea National Weather Service, while others like the Fiji Meteorological Service and the United States National Oceanic and Atmospheric Administration also monitor the basin. Each tropical cyclone year within this basin starts on 1 July and runs throughout the year, encompas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
