The 1936 North American heat wave was the most severe heat wave in the modern history of North America. It took place in the middle of the Great Depression and Dust Bowl of the 1930s, and caused catastrophic human suffering and an enormous economic toll. The death toll exceeded 5,000, and huge numbers of crops were destroyed by the heat and lack of moisture. Many state and city record high temperatures set during the 1936 heat wave stood until the Summer 2012 North American heat wave.〔 The 1936 heat wave followed one of the coldest winters on record. ==Events== The heat wave started in late June, when temperatures across the US exceeded . The Midwest experienced some of the highest June temperatures on record. Drought conditions worsened. In the Northeast, temperatures climbed to the mid 90s °F (around 35 °C). The South and West started to heat up also, and also experienced drought. The heat wave began to extend into Canada. Moderate to extreme drought covered the entire continent. The dry and exposed soil contributed directly to the heat as happens normally in desert areas as the extreme heat entered the air by radiation and direct contact. Reports at the time and explored in the definitive works on the Dust Bowl told of soil temperatures reaching in excess of at the four inch/10 cm level in regions of the Dust Bowl; such soil temperatures were sufficient to sterilize the soil by killing nitrogen-fixing bacteria and other microbes, delivering the final blow in the declining fertility of that soil which had not already blown away. July was the peak month, in which temperatures reached all-time record levels—many of which still stand as of 2012. In Steele, North Dakota, temperatures reached , which remains North Dakota's record. In Ohio, temperatures reached , which nearly tied the previous record set in 1934. The states of Texas, Oklahoma, Kansas, Arkansas, Minnesota, Michigan, North Dakota, South Dakota, Pennsylvania, Louisiana, Nebraska, Wisconsin, West Virginia, and New Jersey also experienced record high temperatures. The provinces of Ontario and Manitoba set still-standing record highs above . Chicago Midway airport recorded or higher temperatures on 12 consecutive days from July 6–17, 1936. Later that summer in downstate Illinois, at Mount Vernon the temperature surpassed for 18 days running from August 12–29, 1936.〔http://blog.chicagoweathercenter.com/feature-graphic/〕 Some stations in the American Midwest reported minimum temperatures at or above such as at Lincoln, Nebraska on July 25, 1936; the next and most recent time this is known to have happened is a handful of minimums during a similar heat wave in late June 1988 but far less intense than that of 1936. The highest nightly low temperature outside of the desert south-west was at Atchison, Kansas during the heat wave of July 1934. August was the warmest month on record for five states. Many experienced long stretches of daily maximum temperatures or warmer. Drought conditions worsened in some locations. Some states were only slightly above average. The heat wave and drought largely ended in September, though many states were still drier and warmer than average. Many farmers' summer harvests were destroyed. Grounds and lawns remained parched. Annual temperatures returned to normal in the fall. 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 heat wave」の詳細全文を読む スポンサード リンク
