摘要
Abstract
The paper aims to study the climatic characteristics and forecast focus of high temperature in East of Hexi Corridor,so as to improve the accuracy of high temperature forecast and to reduce the impact on agricultural production,the authors analyzed high temperature in East of Hexi Corridor from July 17 to 30,2010 by means of synoptic and statistical method from the aspects of climatic characteristics,circulation patterns,physical field and its impact on agriculture,and put forward an early warning index of forecast.The results showed that:the strength of high temperature and the days of duration were historical extremes in July 2010;long duration of hot and dry weather as well as the strong and continuous stability of the continental warm high pressure was the main reasons for the continuous high temperature process;sustained high temperature caused a significant decline in soil moisture,doubled the river flow,and greatly affected a variety of crop production.关键词
