摘要: Abstract The 241 largest snowstorms over the eastern two-thirds of United States during 1950–2000 exhibited considerable temporal variability ranging from 1 storm in three winters to 10 storms 1993/94. peak decadal frequency was 55 (1950s), and minimum 45 (1970s 1980s). east–north-central region experienced greatest number large (148) followed by west–north-central (136) central (133) regions. Regional trends were different. Assessment surface cyclone tracks associated with identified primary tracks: one located leeward side south-central Rocky Mountains east-northeast toward Great Lakes; a second lower Mississippi River basin northeastward third along coastal mid-Atlantic northeast Maine. Temporal differences certain related regional snowstorm ...
