Arab Weather - Weather systems in the Northern Hemisphere are interconnected and interconnected, and any weather event occurring in one region is the result of another weather event in another region. This is because weather systems in the atmosphere are interconnected in their movement, and every action has an opposite reaction.

A low pressure system in the Atlantic Ocean caused a heat wave in the western Mediterranean.

The Maghreb countries and southwestern Europe are affected by the heat dome phenomenon, which has caused a strong and exhausting heat wave in several regions. The temperatures in the Maghreb have been prominent several times on the list of the highest temperatures in the world. The reason for the western Mediterranean being affected by this heat wave and heat dome is due to the presence of a low pressure system that has crossed the Atlantic Ocean, accompanied by a cold air mass that has moved eastward towards the Maghreb. The low pressure in the northern hemisphere causes winds to rotate around it in a counterclockwise direction, as shown in the map below.

One of the physical properties of cold air is that it is heavy, while warm air is lighter. As the cold winds rotate counterclockwise around the low pressure system, they cause the lighter, hot/warm air to rush north from the African continent toward the Maghreb, Spain, and surrounding countries. The heat wave is expected to continue in the coming days.

And God knows best.
