天体引潮力与东亚夏季阻塞高压活动

通过普查东亚地区夏季阻塞高压活动与天体引潮力的关系，发现东亚阻高的建立、持续和崩溃均与天文奇点引潮力共振有关。贝加尔湖和鄂霍次克海阻高的建立是由于该地区在2—3天内遇到≥3个天文奇点的共振加压（同时没有遇到共振减压）而引起的。其后又接连遇到引潮力共振加压而维持，最后遇共振减压而崩溃。其他地区的一些造成重大天气过程的阻高个例，其活动过程所遇的天文条件，也与此类似。

The Relationship Between Celestial Tide-generating Forces and Activities of Blocking High over the Eastern Asia in Summer

The relationship between the celestial tide-generating forces and activities of the blockinghigh over the eastern Asia in the mid summer is described.It is indicated that the formation,per-sistence and collapse of the blocking high over the eastern Asia is related to the resonance of tide-generating forces concerning with the astronomical singularities.The blocking high in the BaikalLake and Sea of Ochotsk forms when the resonance pressure-increasing of three or/and more as-tronomical singularities occurs in two or three days.And then,the high will persist if the reso-nance pressure-increasing occurs successively.Finally,the collapse is brought out by the reso-nance pressure-decreasing.Some cases found in other regions,which lead to severe weather pro-cesses,are similar to those over the eastern Asia.
