Basic Mechanism of Cloudburst
The warm current of air from the terrain region pushes the saturated clouds upwards along the mountains. This updraft movement of warm wind along with clouds forms the Cumulonimbus clouds. Eventually, when it becomes difficult to hold on to so much water vapor and raindrops in the cloud, it sheds water with great strength and velocity. The shedding of intense rainfall over a small area in short-duration causes cloudbursts. One of the most important aspects of cloudbursts is that the Orographic lift is the primary cause of it.
