A preliminary approach to rainy autumns over West China in recent 2000 years

It shows that there are 353 years with rainy autumn from A. D. first to 1949, that is, one in about every 5.5 years. From A. D. 1950 to 1985, there are 8 years with rainy autumn. From A. D. first to 1985, there are two below periods (years with rainy autumn below average), two very below ones, three above ones, and one very above one. It lies in very above period now, and in the coming 30 years, rainy autumns will below.
