Simulation Study of the Connection between Convective Activities around the Philippines and the Storm Track in the North Pacific in Winter
冬季菲律宾周围对流活动与北太平洋风暴轴联系的数值模拟

The impacts of the convective activity anomaly around the Philippines in winter on the variation of the storm track in the North Pacific and its physical mechanism are further investigated by the numerical simulation of IAP 2-L AGCM in this paper It is shown that when the convective activities around the Philippines are active, a forced anomaly wave train, from the equator west Pacific to the west coast of USA via the eastern China, Kamchatka Peninsula, Bering Sea, is formed in the 500 hPa isobaric chart; the meridional circulation of the three cells over the west Pacific intensifies, its location moves northward; and baroclinity in the west half and the eastern end part of the storm track increases, as a result, the storm track in the North Pacific strengthens and moves northward and eastward
