Supercell Side View
A supercell is a thunderstorm characterized by the presence of a mesocyclone: a deep, persistently rotating vertical draft, updraft. Due to this, these storms are sometimes referred to as rotating thunderstorms. Of the four classifications of thunderstorms (supercell, squall line, Multicellular thunderstorm, multi-cell, and pulse storm, single-cell), supercells are the overall least common and have the potential to be the most severe. Supercells are often isolated from other thunderstorms, and can dominate the local weather up to away. They tend to last 2–4 hours. Supercells are often put into three classification types: classic (Normal precipitation level), low-precipitation (LP), and high-precipitation (HP). LP supercells are usually found in climates that are more arid, such as the high plains of the United States, and HP supercells are most often found in moist climates. Supercells can occur anywhere in the world under the right pre-existing weather conditions, but they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rain
Rain is water droplets that have condensed from atmospheric water vapor and then fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mountains, desert climates can exi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lemon Technique
The Lemon technique is a method used by meteorologists using weather radar to determine the relative strength of thunderstorm cells in a vertically wind shear, sheared environment. It is named for Leslie R. Lemon, the co-creator of the current conceptual model of a supercell. The Lemon technique is largely a continuation of work by Keith A. Browning, who first identified and named the supercell.; The method focuses on updrafts and uses weather radar to measure quantities such as height (''echo tops''), reflectivity (such as morphology and gradient), and location to show features and trends described by Lemon. These features include: * ''Updraft tilt'' - The tilted updraft (vertical orientation) of the main updraft is an indication of the strength of the updraft, with nearly vertical tilts indicating stronger updrafts. * ''Echo overhang'' - In intense thunderstorms, an area of very strong reflectivity atop the weak echo region and on the low-level inflow inside side of the storm. * ...

Tornado Climatology
Tornadoes have been recorded on all continents except Antarctica. They are most common in the middle latitudes where conditions are often favorable for convective storm development. The United States has the most tornadoes of any country, as well as the strongest and most violent tornadoes. A large portion of these tornadoes form in an area of the central United States popularly known as Tornado Alley. Canada experiences the second most tornadoes. Ontario and the prairie provinces see the highest frequency. Other areas of the world that have frequent tornadoes include significant portions of Europe, South Africa, Philippines, Bangladesh, parts of Argentina, Uruguay, and southern and southeastern Brazil, northern Mexico, New Zealand, and far eastern Asia. Tornado reports in the U.S. have been officially collated since 1950. These reports have been gathered by the National Climatic Data Center (NCDC), based in Asheville, North Carolina. A tornado can be reported more than once, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mid-latitude
The middle latitudes (also called the mid-latitudes, sometimes midlatitudes, or moderate latitudes) are a spatial region on Earth located between the Tropic of Cancer (latitudes 23°26'22") to the Arctic Circle (66°33'39"), and Tropic of Capricorn (-23°26'22") to the Antarctic Circle (-66°33'39"). They include Earth's subtropical and temperate zones, which lie between the two tropics and the polar circle A polar circle is a geographic term for a conditional circular line (arc) referring either to the Arctic Circle or the Antarctic Circle. These are two of the keynote circles of latitude (parallels). On Earth, the Arctic Circle is currently ...s. Weather fronts and extratropical cyclones are usually found in this area, as well as occasional tropical cyclones or Subtropical cyclone, subtropical cyclones, which have traveled from their areas of formation closer to the Equator. The prevailing winds in the middle latitudes are often very strong. These parts of the world al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles A
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depr ...

Keith Browning
Keith Anthony Browning (born 31 July 1938) is a British meteorologist who worked at Imperial College London, the Met Office, and the University of Reading departments of meteorology. His work with Frank Ludlam on the supercell thunderstorm at Wokingham, UK in 1962 was the first detailed study of such a storm.; His well regarded research covered many areas of mesoscale meteorology including developing the theory of the sting jet. Arguably his greatest talent is his intuitive understanding of complex three-dimensional meteorological processes which he has described more simply using ''conceptual models''. He was elected a Fellow of the Royal Society in 1978. He was president of the Royal Meteorological Society from 1988 to 1990. In 1992, Browning was elected a member of the National Academy of Engineering The National Academy of Engineering (NAE) is an American nonprofit, non-governmental organization.

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and Engli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wokingham
Wokingham is a market town in Berkshire, England, west of London, southeast of Reading, north of Camberley and west of Bracknell. History Wokingham means 'Wocca's people's home'. Wocca was apparently a Saxon chieftain who may also have owned lands at Wokefield in Berkshire and Woking in Surrey. In Victorian times, the name became corrupted to ''Oakingham'', and consequently the acorn with oak leaves is the town's heraldic charge, granted in the 19th century. Geologically, Wokingham sits at the northern end of the Bagshot Formation, overlying London clay, suggesting a prehistorical origin as a marine estuary. The courts of Windsor Forest were held at Wokingham and the town had the right to hold a market from 1219. The Bishop of Salisbury was largely responsible for the growth of the town during this period. He set out roads and plots making them available for rent. There are records showing that in 1258 he bought the rights to hold three town fairs every year. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
