Climate Of Virginia
The climate of Virginia, a state on the east coast of the United States, is mild compared to more northern areas of the United States such as New England and the Midwest. Most of Virginia east of the Blue Ridge mountains, the southern part of the Shenandoah Valley, and the Roanoke Valley, has a humid subtropical climate (Köppen climate classification ''Cfa''). In the mountainous areas west of the Blue Ridge, the climate is warm-summer humid continental (Köppen ''Dfb'') or oceanic climate (Köppen ''Cfb''). Severe weather, in the form of tornadoes, tropical cyclones, and winter storms, impacts the state on a regular basis. Central Virginia received significant snowfall of 20 inches in December 2009. Climate zones The USDA Hardiness Zones for Virginia range from Zone 5A (-20°F to -15°F) in the mountains, to Zone 8A (10°F to 15°F) along the coast. A lot of variations occur because of the state's significant relief. Elevations in Virginia vary from sea level to Mount Roger ...

Mountain Lake, Virginia
Mountain Lake is a freshwater lake located in Giles County near Newport, Virginia in the United States. Along with Lake Drummond in the Great Dismal Swamp, it is one of only two natural lakes in Virginia. It was originally known as Salt Pond, as it was where cattle were given salt. The area is within the ''Mountain Lake Wilderness Cluster''. The Lake Mountain Lake typically covers about , and its level was largely constant at an elevation of during the 19th and 20th centuries. The first known written evidence of the lake was by Christopher Gist of the Ohio Land Surveying Company, in 1751. It subsequently became known as Salt Pond.Parker, B.C., 2003. ''A review of research studies at Mountain Lake, Virginia.'' ''Banisteria'', 22, pp.1-21. Natural lakes are common well to the north, where the Appalachian Range was subject to geologically recent glacial activity.

List Of Wettest Tropical Cyclones In The United States
Tropical cyclones move into the contiguous United States from the Atlantic Ocean, the Gulf of Mexico, and the eastern Pacific Ocean. The highest rainfall totals in the country have been measured across the Gulf Coast of the United States, Gulf Coast and lower portions of the East Coast of the United States, Eastern Seaboard. Intermediate amounts have been measured across the Southwestern United States, Southwest, New England, and the Midwestern United States, Midwest. The northern Great Plains and Northwestern United States, Pacific Northwest have received the lowest amounts, as those regions lie exceptionally far from the tropical cyclogenesis, breeding grounds of North Atlantic tropical cyclone, Atlantic and Pacific hurricane, Eastern Pacific tropical cyclones. The wettest tropical cyclone in the United States storm on record is Hurricane Harvey, which dumped of rain on Southeast Texas in 2017.

Environment Of Virginia
The natural environment of Virginia encompasses the physical geography and biology of the U.S. state of Virginia. Virginia has a total area of , including of water, making it the 35th- largest state by area. Forests cover 65% of the state, wetlands and water cover 6% of the land in the state, while 5% of the state is a mixture of commercial, residential, and transitional. Virginia is bordered by Maryland and Washington, D.C. to the north and east; by the Atlantic Ocean to the east; by North Carolina and Tennessee to the south; by Kentucky to the west; and by West Virginia to the north and west. Due to a peculiarity of Virginia's original charter, its boundary with Maryland and Washington, D.C. does not extend past the low-water mark of the south shore of the Potomac River (unlike many boundaries that split a river down the middle). The southern border is defined as the 36° 30′ parallel north, though surveyor error led to deviations of as much as three arcminutes. The stat ...

Fujita Scale
The Fujita scale (F-Scale; ), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation. The official Fujita scale category is determined by meteorologists and engineers after a ground or aerial damage survey, or both; and depending on the circumstances, ground-swirl patterns (cycloidal marks), weather radar data, witness testimonies, media reports and damage imagery, as well as photogrammetry or videogrammetry if motion picture recording is available. The Fujita scale was replaced with the Enhanced Fujita scale (EF-Scale) in the United States in February 2007. In April 2013, Canada adopted the EF-Scale over the Fujita scale along with 31 "Specific Damage Indicators" used by Environment Canada (EC) in their ratings. Background The scale was introduced in 1971 by Ted Fujita of the University of Chicago, in collaboration with Allen Pearson, head of the National Sev ...

Tornado
A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is often referred to as a twister, whirlwind or cyclone, although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the Earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern. Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than , are about across, and travel several kilometers (a few miles) before dissipating. The most extreme tornadoes can attain wind speeds of more than , are more than in diameter, and stay on the ground for more than 100 k ...

Hurricane Camille
Hurricane Camille was the second most intense tropical cyclone on record to strike the United States, behind the 1935 Labor Day hurricane. The most intense storm of the 1969 Atlantic hurricane season, Camille originated as a tropical depression on August 14, south of Cuba, from a long-tracked tropical wave. Located in a favorable environment for strengthening, the storm quickly intensified into a Category 2 hurricane before striking the western part of Cuba on August 15. Emerging into the Gulf of Mexico, Camille underwent another period of rapid intensification and became a Category 5 hurricane the next day as it moved northward towards the Louisiana–Mississippi region. Despite weakening slightly on August 17, the hurricane quickly re-intensified back into a Category 5 hurricane before it made landfall a half-hour before midnight in Bay St. Louis, Mississippi. At peak intensity, the hurricane had peak 1-minute sustained winds of 175 mph (280 km/h) and a mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Mexico
The Gulf of Mexico ( es, Golfo de México) is an oceanic basin, ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexico, Mexican States of Mexico, states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan, and Quintana Roo; and on the southeast by Cuba. The Southern United States, Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are often referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific Ocean, Pacific coasts). The Gulf of Mexico took shape approximately 300 million years ago as a result of plate tectonics.Huerta, A.D., and D.L.

Hydrometeorological Prediction Center
The Weather Prediction Center (WPC), located in College Park, Maryland, is one of nine service centers under the umbrella of the National Centers for Environmental Prediction (NCEP), a part of the National Weather Service (NWS), which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the U.S. Government. Until March 5, 2013 the Weather Prediction Center was known as the Hydrometeorological Prediction Center (HPC). The Weather Prediction Center serves as a center for quantitative precipitation forecasting, medium range forecasting (three to eight days), and the interpretation of numerical weather prediction computer models. The Weather Prediction Center issues storm summaries on storm systems bringing significant rainfall and snowfall to portions of the United States. They also forecast precipitation amounts for the lower 48 United States for systems expected to impact the country over the next seven days. Advisories are also issued for tropical cyclo ...

Hurricane Gaston
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling round ...

Hurricane Isabel
Hurricane Isabel was the strongest Atlantic hurricane since Mitch, and the deadliest, costliest, and most intense hurricane in the 2003 Atlantic hurricane season. Hurricane Isabel was also the strongest hurricane in the open waters of the Atlantic, both by wind speed and central pressure, before being surpassed by hurricanes Irma and Dorian in 2017 and 2019, respectively. The ninth named storm, fifth hurricane, and second major hurricane of the season, Isabel formed near the Cape Verde Islands from a tropical wave on September 6, in the tropical Atlantic Ocean. It moved northwestward, and within an environment of light wind shear and warm waters, it steadily strengthened to reach peak winds of 165 mph (270 km/h) on September 11. After fluctuating in intensity for four days, during which it displayed annular characteristics, Isabel gradually weakened and made landfall on the Outer Banks of North Carolina, with winds of 105 mph (165 km/h) on September 18.
