Jordan/ On this day in 2013: An exceptional state of atmospheric instability affected the Kingdom

Arab Weather - On November 1, 2013, the Hashemite Kingdom of Jordan was affected by a strong state of atmospheric instability, characterized by heavy rains and active winds concentrated west and south of the capital, Amman. The accompanying weather conditions were considered unusual, as they caused water levels to rise in several areas and mobilized the concerned authorities to deal with the effects of these unstable weather conditions.

Experts at "Arab Weather" explained that the cases of atmospheric instability witnessed by the Kingdom are usually accompanied by random rainfall, which leads to a large disparity in the locations and intensity of rainfall within small geographical areas. This disparity is a dangerous factor, as it contributes significantly to the flow of valleys and the formation of torrents that move between regions without the condition of rainfall in the same region. Cases of atmospheric instability are characterized by rapid changes in the atmosphere within very short periods.

Unstable weather conditions increase the chances of hail and sudden wind activity.

These cases are also accompanied by an increased likelihood of large hail and sudden wind activity. Dense dust belts may also form in desert areas before the onset of thunderstorms. It is expected, God willing, that the upcoming case will be mainly concentrated in the southern and eastern regions of the Kingdom, which requires caution and preparation.

Why are atmospheric instability conditions dangerous in some areas?

Unstable weather conditions pose a risk in some areas, as they may lead to flash floods resulting from heavy rainfall in narrow areas and for short periods of time, especially in mountainous and rocky areas, where rainwater flows from the highlands into valleys. Previous dry seasons also increase the likelihood of floods forming, as rainwater does not easily penetrate the soil, but rather collects on the surface and quickly flows into valleys and channels designated for floods. Therefore, flood channels should be monitored and valleys and low-lying areas should be avoided in the event of unstable weather conditions or depressions.
