This paper discusses autumn rain in West China in terms of climate.The climatic data in West China during 1951 to 1980 are used to divide autumn rain region in West China into three classes.,typical,sub-typical and general areas.The beginning and ending dates of autumn rain in West China are defined.The beginning and ending dates correspond to two sudden changes in atmospheric circulation from summer to winter.Bassed on the mean rainfall of 40 stations selected in the autumn rain region,the cyclic changes in the last thirty years are studied with the method of harmonic analysis.
