Note on the Cool Summer in Tohoku Distriet (2nd Paper)

Abstract

In the present paper it is shown that the standard deviation of the monthly mean air temperature T of August and the frequency of unusual lowness of the five-day-mean of air temperature t in August are abnormally large on the Pacific side of Tohoku district especially at Miyako. The relation between the lowness of temperature and the total failure of the yield of rice crops in Tohoku district is very close.
It was found from the observations during 37 years from 1900 to 1936 that there is a close relationship between the unusual lowness of T or t in July and August at Miyako and the position of the north pole of the earth's axis in the summer or the former winter.
