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.
