Abstract

An analysis of correlation coefficients for climatological data covering the period 1978-2005 for six locations in China has been made in order to highlight the relationships between temperature, precipitation (rain and snow) and snow in summer and in winter. The results show that the evolution of snow depth and area is in good agreement with the climatic change studies from other dataset, with an abrupt jump during the year 1990, and with change cycle about 5 year; The colder air mass from the Western-North China and East-North invade the southern China along western-north-eastern-south aisle and eastern-north-western-south aisle, which makes the influence of snow information on the temperature and precipitation extending to the South China; In the sensitive region, the snow information in three regions all has effect on the temperature and precipitation, the real effect of snow information on temperature and precipitation should be the result of competition among these three snow covered regions; The snow information in Tibet region has larger scale effect on the temperature and precipitation than the other two, which is in accordance with its characteristics able to inspire the larger scale atmospheric circulation.
