The first anniversary of the strongest thunderstorm that affected the Kingdom 14/10/2019

Arab Weather - A strong thunderstorm affected Monday evening to Tuesday morning 14-15 / 10/2019, which led to the formation of strong thunderstorms classified as Shadidah

What is the reason for the formation of the thunderstorm that affected the Kingdom?

This storm came as a result of the eruption of a relatively hot air mass accompanying the Red Sea depression, which increased the temperature increase, as the temperature in the capital Amman at that time reached 35 degrees Celsius, as it is 10 degrees Celsius higher than its rates, which increased global warming.

As we approached the evening and night hours, a cold air mass approached the Kingdom, which led to the formation of a state of instability

What is the cause of the instability that led to this storm?

It was caused by the meeting of a cold air mass with a hot air mass, which caused the formation of thunderstorms, starting from the southern regions around 7:00 pm, and they were moving slowly towards the central regions

Soon the storm developed rapidly and cumulonimbus thunder clouds began to develop and advance towards the central regions due to the southwest wind

The thunderstorm began to intensify in the capital, Amman, near 9:45 pm, as the cumulus clouds began to enter the central regions, as the lightning began to appear from the capital, Amman from the southwestern side, and began to advance rapidly to the northwestern regions, and the thunder clouds were developing rapidly and terrifyingly non stop

What is the scientific reason for the formation of this storm?

The reason for the Kingdom being affected by thunderstorms is the rush of a cold upper basin across the Mediterranean towards northern Egypt, as the Red Sea depression expands towards the Kingdom, and this results in the activity of the East in various regions with active gusts over the mountains.

As a result of the concentration of an air high over the Arabian Peninsula, humid air currents rush through the Arabian Sea through subtropical African regions towards Egypt and the Levant, and due to its association with a relatively hot air mass, the high humidity will be confined to the middle and high air layers, which means the formation of medium and high clouds Interspersed with cumulus clouds

Also, as a result of the drying of the lower atmospheric layers, the bases of cumulus clouds are moving away from the surface of the earth, and this means that part of the rain evaporates before reaching the surface of the earth, as it leads to a cooling / decrease in temperatures inside the cloud, so the air density rises, and it becomes heavier compared to the surrounding air With it, it is then pushed strongly and hits the surface of the earth directly,

These active air currents are known as downward winds, coinciding with the blowing of thunderstorms, and they are active to strong speeds that may raise dirt and dust densely in desert areas.
