Evolution of Traveling Anticyclones in the Far East

Abstract

According to Professor Okada there are three circumstances giving birth to travelling anticyclones in the Far East, i. e. (1) Two or more cyclones appear simultaneously and high pressure develops in their intermediate region. (2) Nocturnal cooling on the land surface. (3) Byproducts of the general circulation of the Earth's stmosphere. In the present note the above circumstances are explained with the aid of same weathermaps.
The travelling anticyclones are numerous in spring and in autumn and those appear in these seasons are more persistent than those in winter and summer. In the latter seasons according to the strong contrast between the continent and ocean of their respective temperature, the high pressure always situates on one of them and the belt-form is not remarkable. On the contrary in spring and in autumn high pressure belt becomes distinct and detached highs are liable to be formed. Figs. 1 and 2 show the development of detached highs cut off at the neck. of wedge-shaped high area. In Figs. 3 and 4 we see nearly the same circumstance as in Figs. 1. and 2, and also the outbreak of cold wind from the western Continent dropping off as a detached high.
Fig. 5 shows the development of an auticyclone between two cyclones and Fig. 6 that of anticyclones surrounding a cyclone.
