Air Mass Calendar

[摘要] The Climate of Japan has been studied from the view of the air-mass calendar. In the cold season (September to June), Japan is decidedly under the influence of the Siberian Air Mass. In the mid-summer (July to August), the North Pacific tropical air controlls the weather of Japan. Sometimes in the early summer, the North Pacific polar air comes from the northeast and results the gloomy weather. Monthly percentage frequencies for each air mass type were tabulated in the Table for 4 representative stations (Fukuoka and Takamatsu for W-Japan, Tokyo for E-Japan and Sapporo for N-Japan.)
