Notes on the Correlations between the Summer Temperature in the Tohoku District and the Wind Velocity at Tateno, and the Surface Water Temperature of the Western Part of Northern Pacific

摘要

In Part I, the correlations between the wind velocity at Tateno and the temperature in summer, especially in August, were studied. A good negative correlation was found between the upper wind in summer and the temperature in that season. But the correlations between the temperature in July and August and the wind velocity in months before it, were found not to be good enough for the practical purpose of forecasting the temperature in that season, and hence of estimating the rice crop in this district.Part II contains the studies on the correlations between the temperature in August in Tohoku and that of the surface water of the western part of the northern Pacific. Two zones of sea surface having different types of correlation were found; the one lies the south presenting a positive correlation, and the other in the north presenting a negative one, and the influence of the former increases as time goes on from winter to spring and summer. Several good positive correlations were found between the temperature in August in Tõhoku and that of the surface water from April to June, which will be useful for the seasonal weather forecasting.
