The method of composite analysis is used to diagnose the deference of the circulation characteristics between the more high temperature year and the less high temperature year for the previous period by using 500 hPa data from 1951 to 1996. The results show that the deference is clear. In the more high temperature year,there are persistent positive anomalies in south of Asia from Jan. to June and the teleconnection over the West Pacific during the winter,and in the less high temperature year,anomalies in south of Asia are negative and the teleconnection over the West Atlantic is obvious. In April,Aleutial low and Alaska high are strong in the more high temperature year and they are week in the less high temperature year. The relationship between high temperature and 74 circulation indexes is analyzed. The results show that there are well positive correlation with the areas of subtropical high in Indian in spring and the position of subtropical high in the northern hemisphere in March,and the negative correlation with indexes of Eurasia longitude correlation in April and of East Asia trough's strength in Jan. and Apr. is notable.
