December 2013 North American Storm Complex
The December 2013 North American storm complex was a significant storm complex that included many different types of severe weather, including a winter storm, a severe ice storm and a tornado outbreak that impacted the central and eastern portions of Canada, parts of the Central Great Plains, the Southern United States, and the northeastern United States from 20 to 23 December 2013. Formed in the South Central United States, the storm headed across the Great Plains towards Canada into Atlantic Canada and northeastern United States where the storm dissipated on 23 December 2013. The storm produced freezing rain and snow to the affected areas which caused massive damage to electric power transmission and trees. The storm resulted in 29 deaths, loss of power to over a million residents and over $200 million in damages. The storm produced similar conditions to the ice storm of 1998 which affected similar areas. Meteorological history On 19 December, an area of low pressure tha ...

Tornadoes Of 2013
This page documents the tornadoes and tornado outbreaks of 2013. Strong and destructive tornadoes form most frequently in the United States, Bangladesh, Brazil and East India, Eastern India, but they can occur almost anywhere under the right conditions. Tornadoes also appear regularly in neighboring southern Canada during the Northern Hemisphere's summer season, and somewhat regularly in Europe, Asia, and Australia. There were 916 tornadoes confirmed in the United States in 2013. One of these tornadoes was 2013 El Reno tornado, the largest ever at 2.6 miles wide. A total of 120 fatalities were confirmed worldwide in 2013: 55 in the United States, 36 in Bangladesh, 24 in China, three in Turkey, and two in Brazil. Despite the high death toll along with several large outbreaks, the year was below average in terms of the number of tornadoes that occurred. This is also the most recent year to have an F5/EF5/IF5 tornado. On April 1, Canada began utilizing the Enhanced Fujita scale ...

Ice Storm
An ice storm, also known as a glaze event or a silver storm, is a type of winter storm characterized by freezing rain. The National Weather Service, U.S. National Weather Service defines an ice storm as a storm which results in the accumulation of at least of ice on exposed surfaces. They are generally not violent storms but instead are commonly perceived as gentle rains occurring at temperatures just below freezing. Formation The formation of ice begins with a layer of above-freezing air above a layer of sub-freezing temperatures closer to the surface. Frozen Precipitation (meteorology), precipitation melts to rain while falling into the warm air layer, and then begins to refreeze in the cold layer below. If the precipitate refreezes while still in the air, it will land on the ground as ice pellets, sleet. Alternatively, the liquid droplets can continue to fall without freezing, passing through the cold air just above the surface. This thin layer of air then cools the rain ...

Electric Power Transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a ''transmission network''. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid. Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (AC) or direct current (DC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution. A wide area synchronous grid, known as an ''interconnection'' in North America, directly connects generators delivering AC power with the same rela ...

Snow
Snow consists of individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide, or Sublimation (phase transition), sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes Nucleation, nucleate around particles in the atmosphere by attracting supercooling, supercooled water droplets, which Freezing, freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns, and Hard rime, rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freezing Rain
Freezing rain is rain maintained at temperatures below melting point, freezing by the ambient air mass that causes freezing on contact with surfaces. Unlike rain and snow mixed, a mixture of rain and snow or ice pellets, freezing rain is made entirely of liquid droplets. The raindrops become supercooling, supercooled while passing through a sub-freezing layer of air hundreds of meters above the ground, and then freeze upon impact with any surface they encounter, including the ground, trees, electrical wires, aircraft, and automobiles. The resulting ice, called glaze (ice), glaze ice, can accumulate to a thickness of several centimeters and cover all exposed surfaces. The METAR code for freezing rain is FZRA. A storm that produces a significant thickness of glaze ice from freezing rain is often referred to as an ice storm. Although these storms are not particularly violent, freezing rain is notorious for causing travel problems on roadways, breaking tree limbs, and downing power l ...

National Oceanic And Atmospheric Administration
The National Oceanic and Atmospheric Administration (NOAA ) is an American scientific and regulatory agency charged with Weather forecasting, forecasting weather, monitoring oceanic and atmospheric conditions, Hydrography, charting the seas, conducting deep-sea exploration, and managing fishing and protection of marine mammals and endangered species in the US exclusive economic zone. The agency is part of the United States Department of Commerce and is headquartered in Silver Spring, Maryland. History NOAA traces its history back to multiple agencies, some of which are among the earliest in the federal government: * United States Coast and Geodetic Survey, formed in 1807 * National Weather Service, Weather Bureau of the United States, formed in 1870 * United States Fish Commission, Bureau of Commercial Fisheries, formed in 1871 (research fleet only) * NOAA Commissioned Corps, Coast and Geodetic Survey Corps, formed in 1917 The most direct predecessor of NOAA was the Enviro ...

Atlantic Canada
