Weather of Arabia - Many of us hear that the Kingdom will be affected by a state of weather instability, and that certain areas of the Kingdom will witness rain, while other nearby areas are expected to have stable and dusty weather with no significant rain, and a warning of torrents forming in some areas as a result of heavy rain is expected. It rains there.

 

Firstly, how do atmospheric instability arise?

 

Cases of atmospheric instability arise as a result of the meeting of cold, descending air from the upper layers of the atmosphere with other rising, hotter, warmer air in the lower layers of the atmosphere (which are called descending and rising currents). This coincides with the presence of sufficient moisture in the structural layers of the atmosphere that helps build cumulonimbus clouds. Thunderstorms, and when these factors combine, rain falls, which is random in nature due to the local structure of clouds, which usually form within narrow geographical areas and disappear when they extend to other areas.

 

Do the southern and eastern regions receive higher rainfall than the rest of the Kingdom in cases of instability?

Mostly, moisture flows from the south towards the northeast, coinciding with the activity of the Red Sea depression, which is usually active in the fall. As a result of the combination of all these factors, the process of forming cumulus clouds begins, which usually takes the same path that moisture takes, “from the south to the north and the northeast,” thus forming Thus, the southern, southeastern, and eastern regions of the Kingdom are the preferred places for thunderclouds to form, and rain falls in these areas more than any other region in the Kingdom, taking into account the difficulty of predicting cases of instability and locations of precipitation due to the randomness of rain in such cases.
