The Possibility of Forecasting of the Autumn Rainfall in North Manchuria
[摘要] 1. The correlation coefficient between the monthly number of sunspots and the late autumn rainfall in North Mauchuria is shown less than 0.351±0.144. (1898-1935).2. There is the inverse correlation as high as -0.698±0.064 (1907-1936) between the monthly means of atmospheric pressure of May and the amount of rainfall of October in Harbin. Besides there are higher correlation between the May pressure in Harbin and the October rainfall in Antah, Yaomen, Sansing and Kungchuling. Therefore the air pressure of May in Harbin is able to predict the late autumn rainfall of various regions in North Manchuria.3. It was found that the predic_??_ing formula of October rainfall in Harbin Y1=569.0-12.8 X1, showed less deviation in forecasting than that of another places.
