本文研究了南亚夏季的100毫巴型。发现青藏高原100毫巴反气旋是北方亚热带地区一个大而稳定的环流特征，并围绕其平均位置振荡。500毫巴上的西太平洋副热带高压在其振荡过程中，在远东陆地上空有一个周期性的运动。当100毫巴高压离开高原时，500毫巴西太平洋副热带高压向陆地推进，当100毫巴高压返回高原时，西太平洋高压向陆地后退。这是预报夏季西太平洋高压移动的一个较好判据。
The 100-mb Patterns in southern Asia in summer are investigated. It is found that the 100-mb anticyclone over the Tibetan Plateau is a large and stable circulation feature in the subtropical region of the northern hemisphere, and that it oscillates about its mean position. During its oscillation the West-Pacific subtropical anticyclone at 500 mb level shows a cycle of movement over the land of the Far East. When the 100-mb anticyclone leaves the plateau, the West-Pacific subtropical anticyclone at 500 mb level advances to the land, while the 100-mb anticyclone returns to the plateau, the West-Pacific anticyclone retreats from the land. This is a good criterion for forecasting the movement of West-Pacific anticyclone in summer.
