Abstract
In this paper the author presents a method of long range forecasting of the monthly mean air temperature T of August in Tohoku district. It is shown that this temperature T is derivable from the correlation (>0.85) between T and the difference of pressures at Husan and Zyosin of December of the former year. T has a period of about 30 years, and during the first 20 years T is comparatively low, and during the remaining 10 years is comparatively high.
