Weather of Arabia - Cases of air instability within one of the famous scientific terms, especially in the spring and autumn seasons. These cases are completely and radically different from the depressions in the air, so what is the difference and how do these conditions affect the region and the kingdom through the report.
When cold air currents converge across the higher layers of the atmosphere in conjunction with the convergence of hot and warm air currents across the lower atmosphere, the atmosphere coincides with sufficient moisture.
At this convergence, what is known as a state of air instability arises, where the cumulative clouds of vertical growth multiply and the rains begin to fall in separate areas of the Kingdom.
Weather instability is characterized by irregularity in the distribution and intensity of rain precipitation, where its impact is not regular, so it can witness an area of rain and thunderstorms and another area close to it that does not experience any rain. Heavy rains can be caused by heavy rains in a narrow and limited geographical focus, which works to form torrents and floods Therefore, instances of air instability are considered dangerous compared to depressions.
Air instabilities differ from air depressions altogether, as air depressions in which the precipitation falls are uniform in their distribution, so rains start from the northern regions and extend to the central and later southern and eastern regions, unlike instances of instability in which the rains are of a local and random nature and perhaps areas that do not fall in rain throughout the impact of the situation Often in depressions, the weather is cold, while in instability conditions may be warm.
• Downward winds or strong winds during thunderstorms.
