大阪地域における夏季夜間の風系パターンと気温の関係

抄録

Since Osaka plain faces the Osaka bay, land and sea breezes tend to develop there. To reveal the relationship between the land and sea breezes and air temperature in summer night, we classified the wind systems in Osaka area by using a cluster analysis and examined the relationship between each wind pattern and air temperature distribution. The result shows that sea breezes at night make air temperature higher in Osaka area. When a land breeze develops, the occurrence of a land breeze is relevant to a decrease of air temperature.
