List Of Northeast Snowfall Impact Scale Winter Storms
The Northeast Snowfall Impact Scale (NESIS) is a scale used to categorize winter storms in the Northeast United States. The scale was developed by meteorologists Paul Kocin and Louis Uccellini, and ranks snowstorms from Category 1 ("notable") to Category 5 ("extreme"). Only two historical blizzards, the 1993 Storm of the Century and the North American blizzard of 1996 are rated in the 5 "extreme" category. The scale differs from the Saffir–Simpson Hurricane Scale and Fujita Scale, which are used to classify tropical cyclones and tornadoes, respectively, in that it takes into account the number of people affected by the storm. The scale, as devised, is intended chiefly to assess past storms rather than assist in forecasts.Kocin and Uccellini, pp. 269–270 List There are two available values for NESIS. The original values that Paul Kocin and Louis Uccellini computed for storms in their original 2004 work "A Snowfall Impact Scale Derived From Northeast Storm Snowfall Distr ...

NESIS Description NCDC
The Northeast Snowfall Impact Scale (NESIS) was created to measure snowstorms in the U.S. Northeast in much the same way the Saffir-Simpson Hurricane Scale records hurricane intensity and the Enhanced Fujita Scale with tornadoes. The Scale NESIS was created by Paul Kocin of The Weather Channel and Louis Uccellini of the National Weather Service, classifies storms in one of five ways that range from ''Notable'' (the weakest designation) to ''Significant'', ''Major'', ''Crippling'', and ''Extreme''. storms have on the economy and transportation throughout the major cities in the Northeastern United States as well as the country as a whole.http://www.ncdc.noaa.gov/snow-and-ice/nesis.phpref The variables measured on the scale include area, amount of snowfall, and the number of people living in the path of the storm. These numbers are calculated into a raw data number ranging from "1" for an insignificant fall to over "10" for a massive snowstorm. Based on these raw numbers, the ...

North American Blizzard Of 1947
The North American blizzard of 1947 (also known as the Great Blizzard of 1947) was a record-breaking snowfall that began without prediction on Christmas and brought the northeastern United States to a standstill. The snowstorm was described as the worst blizzard in the region after that of 1888. The storm was not accompanied by high winds, but the snow fell silently and steadily. By the time it stopped on December 26, accumulation had reached 26.4 inches (67.1 cm) in Central Park in Manhattan. Similar or greater accumulations were noted in all of metropolitan New York and New Jersey, as well as in upstate New York Upstate New York is a geographic region consisting of the area of New York State that lies north and northwest of the New York City metropolitan area. Although the precise boundary is debated, Upstate New York excludes New York City and Long Is ..., Connecticut, and most of the Mid-Atlantic States, mid-Atlantic region.

North American Blizzard Of 2003
The Blizzard of 2003, also known as the Presidents' Day Storm II or simply PDII, was a historic and record-breaking snowstorm on the East Coast of the United States and Canada, which lasted from February 14 to February 19, 2003. It spread heavy snow across the major cities of the Northeastern and Mid-Atlantic states, making it the defining snowstorm of the very snowy winter of 2002–2003. All cities from Washington DC to Boston were covered in of snow and those cities were brought to a standstill due to problems caused by temperatures and the snow. In Baltimore and Boston, this was the biggest snowstorm on record, with 28.2 and 27.5 inches (71.6 and 69.9 cm) respectively. Synoptic setup The severity of the Blizzard of 2003 can be attributed to the unusually favorable atmospheric conditions surrounding the storm ( synoptic conditions). Most notably, the storm allowed for cyclogenesis off of the coastal Carolinas, a feature that is common to most major winter storms in ...

December 2000 Nor'easter
The December 2000 nor'easter was a significant winter storm that impacted the Mid-Atlantic and New England regions of the United States around the end of the month. It began as an Alberta clipper that moved southeastward through the central United States and weakened over the Ohio Valley. However, it redeveloped off the coast of North Carolina and moved northward as it intensified. It moved into central Long Island and eventually tracked northward into New England. The storm dropped heavy precipitation throughout the Northeast, especially in northern New Jersey and eastern New York, where snowfall often exceeded . Even so, as it struck on a weekend, its effects were generally minor and mostly limited to travel delays, traffic accidents, and business closures. Synoptic history The storm developed as an Alberta clipper-type low pressure area that moved southeastward across the Great Plains and Midwest. Throughout North Dakota, Minnesota and Iowa, moderate snowfall accompanied the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
April Fool's Day Blizzard
The 1997 April Fool's Day blizzard was a major winter storm in the Northeastern United States on March 31 and April 1, 1997. The storm dumped rain, sleet, and snow from Maryland to Maine leaving hundreds of thousands without power and as much as three feet of snow on the ground. Due to the date, many people took warnings of the storm less seriously. Plows had started to be put away for the summer and hardware stores still had to sell shovels again even though they already put out patio furniture. One commuter called it " Mother Nature's April Fools' Joke." Evolution of the storm Formation The storm started as a surface low pressure system over the Ohio River Valley that was generated by an area of strong jet stream energy carving out an active upper air low pressure trough on Sunday March 30. The low pressure system brought rain to much of the Ohio Valley. When the storm arrived in eastern New York and western New England, the areas received light rain. The storm moved off t ...

February 1995 Nor'easter
The February 1995 nor'easter was a significant nor'easter that impacted the Mid-Atlantic and New England regions of the United States around the beginning of the month. It was the only major nor'easter of the 1994–1995 winter.Kocin and Uccellini, p. 590 Synoptic history The initial low pressure area tracked eastward from the southern Great Plains on February 2. Gradually intensifying, it was situated over eastern Kentucky by 0000 UTC on February 4. As the system entered West Virginia, a secondary low began to develop over South Carolina. The new low quickly deepened, and absorbed the primary low over West Virginia into its expanding and strengthening circulation. It continued to rapidly mature as it moved northward from eastern Maryland, and it hugged the coast as it moved northeastward towards southern New England. The cyclone reached a strength of 980 millibars while located south of Long Island. It crossed eastern New England and reached its peak intensity, with a minimum ...

February 1987 Nor'easter
The February 1987 nor'easter was a significant winter storm in the US that impacted the Mid-Atlantic States around the end of the month. It delivered 8–12 hours of heavy, wet snowfall to several states from West Virginia to New York between February 22 and February 24. The storm was both preceded and followed by relatively warm temperatures,Kocin and Uccellini, p. 556 causing the snow to rapidly melt.Kocin and Uccellini, p. 557 The mild conditions were the result of a moderate anticyclone over the region that deteriorated as the nor'easter approached. Cold air damming likely took place prior to the storm's formation. The nor'easter evolved from a complex series of low pressure areas. Eventually, the multiple center consolidated and a primary cyclone took hold along the Carolina coast. This low rapidly strengthened as it tracked northeastward. Upon reaching the Maryland coast, it turned more towards the east and intensified further to attain a minimum barometric pressure of 964 ...

Northeastern United States Blizzard Of 1978
The Northeastern United States blizzard of 1978 was a catastrophic, historic nor'easter that struck New England, New Jersey, Pennsylvania and the New York metropolitan area. The Blizzard of '78 formed on Sunday, February 5, 1978, and broke up on February 7. The storm was primarily known as "Storm Larry" in Connecticut, following the local convention promoted by the Travelers Weather Service on television and radio stations there. Snow fell mostly from Monday morning, February 6, to the evening of Tuesday, February 7. Connecticut, Rhode Island, and Massachusetts were hit especially hard by this storm. Boston received a record-breaking of snow; Providence also broke a record, with of snow; Atlantic City broke an all-time storm accumulation, with , two Philadelphia suburban towns in Chester County received while the City of Philadelphia received . Nearly all economic activity was disrupted in the worst-hit areas. The storm killed about 100 people in the Northeast and injured ...

December 1969 Nor'easter
The December 1969 nor'easter was a strong winter storm that mainly affected the Northeastern United States and southern Quebec between December 25 and December 28, 1969. The multi-faceted storm system included a tornado outbreak, record snow accumulations, a damaging ice storm, and flooding rains. The storm developed over Texas by December 25 and advanced eastward, spawning over a dozen tornadoes in Louisiana, Georgia, and Florida. Upon reaching the Eastern Seaboard, the cyclone turned northeastward and intensified into a powerful nor'easter. On December 26 and 27, the storm's forward movement slowed to a drift, causing very heavy snow over Upstate New York, Vermont, and southern Quebec. Warm onshore winds, caused by a storm track close to the shore, allowed precipitation to change to sleet and rain in central and eastern New England. Where precipitation remained as snow, accumulations reached or more, crippling travel. Drifts up to high blocked roadways, isolating some commun ...

February 1969 Nor'easter
The February 1969 nor'easter was a severe winter storm that affected the Mid-Atlantic and New England regions of the United States between February 8 and February 10.Kocin and Uccellini, p. 450 The nor'easter dropped paralyzing snowfall, exceeding in many places. New York City bore the brunt of the storm, suffering extensive disruption. Thousands of travelers became stranded on roads and in airports. The storm killed at least 94 people. City schools were closed for several days and some areas of the city remained uncleared for over a week. New York Mayor John Lindsay was criticized for failing to respond to the snowstorm adequately. Synoptic history An area of low pressure moved generally eastward from Oklahoma and produced heavy rains from Missouri to Ohio on February 8. By February 9, it had reached Kentucky. A new, secondary low pressure system formed over Georgia along the warm front associated with the primary low. As the secondary low matured along the U.S. East Coast, the ...

North American Blizzard Of 1966
The Blizzard of 1966 swept across most of the United States and Canada east of the Rocky Mountains on January 26, 27, 28 and 29, and brought record low temperatures, high winds and heavy snowfall in its wake. Within days, at least 142 people had been killed — 31 had frozen to death, 46 died in fires that started while people were trying to heat their home. Others died from heart attacks while shoveling snow or pushing cars, or traffic accidents caused by slick roads. The death toll reached 201 by Wednesday, February 2, as the storm eased. On Monday, January 31, federal government employees in Washington were excused from reporting to work and international airports were closed from Boston to Washington, D.C. or of snow fell on Oswego, New York, and the additional accumulation raised the snow level to in Norfolk, Virginia. By February 1, additional snow brought the level to or to Oswego. (This held the record for the most snowfall in a single storm in Oswego until the L ...

Ash Wednesday Storm Of 1962
Ash or ashes are the solid remnants of fires. Specifically, ''ash'' refers to all non-aqueous, non-gaseous residues that remain after something burns. In analytical chemistry, to analyse the mineral and metal content of chemical samples, ash is the non-gaseous, non-liquid residue after complete combustion. Ashes as the end product of incomplete combustion are mostly mineral, but usually still contain an amount of combustible organic or other oxidizable residues. The best-known type of ash is wood ash, as a product of wood combustion in campfires, fireplaces, etc. The darker the wood ashes, the higher the content of remaining charcoal from incomplete combustion. The ashes are of different types. Some ashes contain natural compounds that make soil fertile. Others have chemical compounds that can be toxic but may break up in soil from chemical changes and microorganism activity. Like soap, ash is also a disinfecting agent (alkaline). The World Health Organization recommends ash o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
