The 1936 North American cold wave ranks among the most intense cold waves in recorded North American meteorological history. The states of the Midwest United States and the Prairie Provinces of Canada were hit the hardest, but only the Southwest and California largely escaped its effects. February 1936 was the coldest month recorded in the states of North Dakota, South Dakota, and Minnesota, and rivals that of 1899 the coldest February on record for the continent as a whole. Only a few parts of the Great Basin, the Bering Sea coast of Alaska and the Labrador Sea coast of Canada were even close to their long-term means. The 1930s had previously seen some of the mildest winters in recorded North American climatic history – 1930/1931 in the northern Plains and Western Canada, 1931/1932 in the East, 1932/1933 in New England and 1933/1934 in the Western United States.〔Diaz, Henry F. and Quayle, Robert G.; (‘The 1976-77 Winter in the Contiguous United States in Comparison with Past Records’ ); ''Monthly Weather Review'', 106 (1977), no. 10, pp. 1392-1422〕 The northern plains had during the previous eleven years experienced six of their ten warmest Februaries between 1895 and 1976 – those of 1925, 1926, 1927, 1930, 1931 and 1935〔National Oceanic and Atmospheric Administration; (Central NWS Region Average February Mean Temperature, 1895-1976 )〕 – with only February 1929 being severe during this period. Despite a warm March over most areas east of the Rockies, the extended winter from October to March was the fifth coldest on record over the conterminous United States and the coldest since 1917.〔National Oceanic and Atmospheric Administration; (Contiguous United States Temperatures: October to March )〕 The cold wave was followed by one of the hottest summers on record, the 1936 North American heat wave. ==Beginnings== The 1936 cold wave began in the Plains in November of 1935, when temperatures were well below normal in all areas west of the Mississippi, and the northwestern states and North Dakota had one of their coldest Novembers on record. December 1935 saw cold weather spread to the eastern half of the USA, when most places were much below average, and Florida saw its coolest December on record, with a mean temperature of . Due to chinook winds, however, Montana and British Columbia were significantly above average and the eastern Plains near normal. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1936 North American cold wave」の詳細全文を読む スポンサード リンク
