The stronger mass convergence, moisture convergence and upward motion are located in the eastern and southern part of the depression.

强烈的质量辐合、水汽辐合和上升运动等位于低压东侧和南侧。

Although the water vapor convergence in the surface boundary layer is very important, the rainfall amount depends on the vertically integrated moisture flux convergence.

虽然边界层的水汽辐合对降水的形成很重要，但降水量的大小取决于整层水汽通量辐合的大小。
