THE STRUCTURE OF GENERAL CIRCULATION OVER CONTINENT OF ASIA IN SUMMER

In this paper, an analysis is made on the structure of the July mean flow field at 850 mb, 700 mb. 500 mb over the continent of Asia during the year 1951-1955 and the mean contours at 200 mb over Asia for July and August, 1956. The vertical cross-sections of the mean flow and temperature fields along 750E, 900E, 1050E and 1200E for July and August, 1956 have been constructed. The three-dimensional flow structure over continent of Asia is constituted of the following three basic currents:(1)the westerlies of middle latitudes,(2)the upper level tropical and subtropical esterlies, and(3) the south-westerly monsoon under the upper level tropical and subtropical easterlies.
