What are the forming factors of rainstorm?
The formation process of rainstorm is very complicated. It needs rich water vapor in the atmosphere, especially the saturated layer in the lower troposphere is thick; There must be a strong updraft, so that water vapor can form clouds and cause rainfall; There should be long-lasting heavy precipitation, that is, the weather system moves slowly or repeatedly; There should be favorable terrain uplift, which leads to the concentration of rain belts in a certain place and contributes to local heavy rain. As far as weather system is concerned, rainstorm is often the product of the interaction and restriction of various weather systems, and the activities of cyclones, fronts, troughs, vortices, shear lines, typhoons and other systems can all contribute to rainstorm.
Rainstorms are very harmful and often cause unexpected floods.
