Latest global developments: The polar vortex is cooling and developing rapidly, and autumn is approaching the region.

Arab Weather - We at Arab Weather are still following the latest weather developments in the northern hemisphere, particularly the development of the polar vortex. The development and growth of the polar vortex is linked to increased chances of cooler air masses rushing towards the middle latitudes, thus improving the chances of autumn-like air masses reaching the south and Arab regions.

The polar vortex is developing rapidly and autumn is approaching the region.

Arab Weather forecasters said that the latest weather forecasts indicate a continued cooling of air around the Arctic Circle, resulting in further drops in atmospheric pressure and increased wind circulation, generating more cold air masses and low-pressure systems around the polar regions.

This process also subsequently leads to an increase in the southward curvature of the polar jet stream, allowing cold air and cold air masses to reach Europe and later the Mediterranean and Arab regions.

What is the polar vortex?

The polar vortex is a low-pressure area surrounded by strong winds that circulates around the North Pole, and plays a key role in determining temperatures and the distribution of cold air masses in the Northern Hemisphere.

Is autumn already approaching?

Undoubtedly, the arrival of cold autumn air masses towards lower latitudes in the coming weeks depends on the continued development of the polar vortex and the increasing coldness of the air around the Arctic Circle. The rush of cold air masses and the undulation of the polar jet stream towards the south will cause the high-pressure areas to retreat from the region, thus increasing the coldness of the atmosphere and allowing cold, moist air masses to reach the region.

The autumnal equinox in the northern hemisphere falls on September 22nd, when the daylight and night hours are equal. The sun's apparent journey southwards begins, with the sun being directly overhead at the Tropic of Capricorn on December 21st, the winter solstice and the beginning of the winter solstice. On this day, the night is at its longest in the northern hemisphere.
