中文摘要	利用河西走廊东部武威市1971～2005年5～9月日极端最高气温≥35℃高温个例和其它相关气象资料,系统分析了该区高温的时空分布、持续性、强度和异常天气气候特征,同时分析了影响河西走廊东部高温天气形成的主要环流特征.结果表明,河西走廊东部高温天气主要发生在东北部沙漠边缘;高温天气主要出现在盛夏7～8月;河西走廊东部高温天气从20世纪90年代后期至今明显增多;强高温日大多出现在持续高温时段内;随着气候变暖,高温日数明显增多,强度增强;高温日数和强度与当地年度干旱有很好的对应关系,年度干旱指数越大,高温强度越强,出现高温日数相对也较多;高温天气出现在副热带高压控制及影响的区域内.
英文摘要	Using the greater than or equal to 35℃ high temperature events and the observed meteorological data from 1971 to 2005 of Wuwei in east Hexi Corridor, the temporal and abnormal spatial distribution features, continuation, strength and unseasonable synoptic and climatic characteristics of the area are studied in detail. The results show: high temperature mainly occur in the northeast edge of the desert in east Hexi Corridor; high temperature weather chiefly appears in July and August every year; high temperature weather has increased significantly from the late 1990s to today; and strong high temperature occur in the sustained periods of high temperature. With the warming of the climate, the days and the strength of high temperature increase obviously; the days and the strength of high temperature have very close correspondence with drought, the greater the annual drought index is, the higher the temperature becomes, and the more days of high temperature. High temperature occurs in the region of subtropical high control and influence. Based on the analysis of characteristics of the atmospheric circulation of the region, the focus and difficulties of short-term forecasting are discussed.
