What is the thermal dome that threatens Jordan with one of the strongest heat waves?

Weather of Arabia - Sinan Khalaf - What is the phenomenon of the thermal dome? That dome, which today threatens Jordan today, with one of the strongest heat waves since the beginning of the climate records in the Kingdom.

What is the heat dome phenomenon?

It is an atmospheric phenomenon that occurs as a result of the formation of an area of high atmospheric pressure in the upper atmosphere, and with the solar heating of the earth’s surface, a thermal depression forms above its surface, which leads to the raising of hot air to the top through ascending air currents, and the upper elevation reverses the ascending hot currents and bounces back Downward, which causes hot air to remain trapped in the lower layers and thus the temperature rises dramatically in a phenomenon known as the heat dome.

And the control of this thermal dome over the region comes to the distribution of air systems in the northern hemisphere, where it is expected that the upper depressions associated with the cooler air will rush towards central Europe and reach the center of the Mediterranean Sea, and this necessarily leads to the intensification of the upper air elevation above Northern Arabia and the Levant.
