The risk of atmospheric instability sometimes outweighs the danger of low airways

Weather of Arabia - The term state of atmospheric instability is one of the common scientific terms, especially in the transitional periods between the seasons, perhaps the most prominent of which is the spring and autumn seasons. Instability differs from the usual depressions, so that they are sometimes more dangerous and damaging than the depressions. Why ..?

What are the cases of air instability ..?

Conditions of atmospheric instability are defined as the convergence of warm and hotter air currents in the surface layers of the atmosphere (near the surface of the earth) with cold air currents in the upper atmosphere (far from the surface of the earth) with the presence of proportions of moisture in the atmosphere, when the above conditions are completed The so-called state of atmospheric instability arises as cumulative clouds multiply and the rains begin to fall in limited geographical areas and the rains are characterized by irregularity in their intensity and geographical distribution, where a region may witness heavy rain and others close to it that do not witness any rain or witness slight precipitation that is negligible while the other is exposed. For torrents, it is difficult for forecasters to accurately locate precipitation as in depressions, and there is a prominent feature, which is the most important in those cases, which is the sudden reversal of the atmosphere from stability to turbulence in a short period of time.

Cases of instability are accompanied by many weather phenomena, perhaps the most prominent of them ....

• Heavy rains and severe thunderstorms in strong cases.

• Hail showers of different sizes, with large sizes and high intensity in some cases, which cause many damages.

• Downward winds, and strong sandstorms in the event that these situations affect desert areas.

Why are instability situations more dangerous than depressions?

Instability is considered dangerous and its danger is almost more severe than atmospheric depressions at times and may lead to loss of life and property, as happened in 2018 (the Dead Sea disaster). Perhaps the main reasons that make air instability dangerous are ..

Large quantities of rain fall in narrow and limited geographical areas, which causes a significant rise in the water level, valley runoff, and the formation of torrents and floods in limited areas where large amounts of rain, up to 100 mm of rain, can fall in a short period of time and in a narrow geographical area, which causes With heavy losses, unlike the depressions, which can cause 100 mm of rain at long intervals and in wide geographical areas, which does not cause great damage and losses as in cases of instability.

• The strong downward winds that accompany strong instability situations contain a high risk of sandstorms forming and of metal objects flying and falling from high distances to the surface of the earth.

• The hail showers that fall with high intensity and large sizes cause great damage to crops, car structures, and glass.
