When it rains in the Gobi desert, it will form a raging torrent. What is the reason?

First of all, the climate of the Gobi desert determines the dry climate. If it rains, it must be strong convective weather such as heavy rain, and the rainfall is heavy and urgent.

Secondly, the Gobi desert is generally formed by dry rivers. The terrain is low, and the rainwater flows back here, and the surrounding area is generally flat, which is convenient for rainwater to flow to the river.

Finally, because there is no vegetation in the Gobi desert, the demarcation point is mostly rocky landform, and the ground water absorption effect is not good, and the rainwater flows directly from the surface, so the water volume is large.
