Abstract:According to the data of temperature and precipitation in Shanxi Provi nce during the past half century, we analyse the features of climate change in ShaInxi:Rainfall has slightly decreased since the end of 1970's;while the tempe rature has obviously increased from 1975 and especially much higher in 1990's .T he relation between the climate change and the circulation systems over Northern Hemisphere are detected: if the East Asian Trough and Ural Mountains High are s trengthening at the same time, then the rainfall inclines to be much more than t he means, and the temperature will begin to go up.On the contrary,if the East As ian Trough and Ural Mountains High are weakening at the same time, then the rain fall inclines to be less than the means, and the temperature will begin to come d own.
