Thermodynamical Aspects on Siberian High, Ogasawara (or North-Pacific) High and Okhotsk High, ruling the Climate of Japan

[摘要] The Siberian High is of a relatively shallow vertical structure, whose excess of pressure is due to the excess of density in the lower troposphere. The North-Pacific High extends into the stratosphere, in which region it is colder than the normal for the latitude and the time of the year. General westerly winds prevailing over Japan and the west-east tendencies of barometric centres clearly show that the Siberian High is a cold anticyclone and the North-Pacific High is a warm one. The cold migratory anticyclones are mainly generated by the cold outbursts from the Siberian High brought southward in the rear of depressions and are amalgamated into the warm North-Pacific High.
