A Study of Climate Variability in Zedang during 1960-1999

According to the data of temperature and precipitation in Zedang from January,1960 to April,1999,the climate of Zedang was analysed.The results show that the precipitation of Zedang for 40 years appears to be descending (-8.97mm/10 years),the precipitation in winter appears to be ascending (2.16mm/10 years),and the temperature appears to be going up (0.230℃/10 years),especially in the middle-latter period of 1970′s to the middle period of 1980′s.The warming trend in winter is more than that in summer.For this reason,in terms of the limit of the middle stage of 1980′s the climate of Zedang for 40 years might be divided into 2 stages,the former is a cold period,and the latter is a warm period.
