By using the monthly mean temperature data from surface up to 30hPa in 1958~1995 over Lhasa and Nanjing,investigated are several climatic features and vertical distribution characteristic of monthly,seasonal and annual temperature variability over Lhasa with the conditions over Nanjing compared.The relationship is also discused between the climatic change at low stratosphere and middle troposphere over the two stations on one hand,and total ozone at high latitudes over Eurasian continent and the south Asia high on the other hand.
