Weather of Arabia - cases of atmospheric instability are characterized by heavy rains over short periods of time, and they usually form in narrow geographical ranges or limited areas, and are not comprehensive like air depressions. A state of air instability may form at the top of the mountain, but the other parts at the bottom of the mountain remain stable completely.

Instability situations may become dangerous in some areas, as they result in the formation of flash floods, due to the precipitation of large amounts of rain in a narrow geographical range, and in a short period of time, especially in rocky areas, or mountainous areas that Rain water flows from the top to the valley.

The existence of previous dry seasons helps in the occurrence of torrential rains because the rainwater does not find streams for it to be absorbed into the ground, so the water keeps accumulating on the surface of the earth, and it begins to flow very quickly in the valleys of the torrents or the streams of the torrents that you previously dug, and the speed of flow of this water reaches 10 m / s, so it sweeps everything in its path, even large objects such as vehicles and rocks, then it reaches estuaries that may be new, and it may flow into a river, sea, or lake.

These torrents are also dangerous because of the mixing of water with dust that increases the turbidity of the water, and it becomes difficult to see the content of the water and the bodies that move with it, and large rocks that move quickly with it can collide and strike the human body.

These torrents may move to a stable area, surprising the population, or these torrents may get stronger, leaving their streams, and striking other areas that may be populated, so the torrents must be monitored, and away from valleys, low areas, and torrential streams when there is a state of instability. atmospheric, or atmospheric depressions.
