Abstract:By using the data of daily mean temperature, daily maximum and minimum tempe rature, precipitation, sunshine duration from 1961 to 2005, the inte r annual, interdecadal the seasonal climate changes are analyzed. The results a re as follows: Firstly, the annual and the seasonal temperature are rising in recent 45 years, especially, the trend of temperature increase is the most remarkable in w inter, and the recent 10 years is the warmest period. Secondly, the change of monthly mean maximum temperature is not significant, whe reas monthly mean minimum temperature is rising in the last 10 years. Thirdly, annual precipitation is in creasing and its variability is 8.19mm/10a, and so does the precipitation in wi nter and summer, but precipitation in spring and autumn are slowly decreasing. M eantime, annual precipitation in recent 10 years is also increasing, the precipi tation in winter is the largest but in autumn is the smallest. Finally, sunshine duration and mean wind speed in each period are all decreasing.
