On the Rain produced by Invasion of Warm Air Mass

[摘要] The rain often begins in the southerly air; current without obvious depression or discontinuity. Such the rain are produced by the invasion of warm air mass, and the cloud is formed by the contraction of air column due to the latitude effect. It is shown that the cloud is formed firstly in the upper layer of the air mass and then it lowered with the northward motion of the air mass.
