Monitoring the consequences of a polar vortex split

Arab Weather - Weather experts at the Arab Weather Regional Center are following up on the latest numerical computer modeling indications regarding the possibility of a split in the polar vortex due to the formation of a high-pressure area above the Arctic Circle, and its reflection on the behavior of the polar jet stream and its impact on global weather patterns in the coming period.

 

Polar vortex splitting is caused by the formation of a high-pressure area above the polar vortex.

Meteorologists at the Arab Weather Regional Center said that as a result of the weakness of the western polar winds above the Arctic Circle and the descent of polar air from the upper levels of the atmosphere close to the Earth's surface, which caused the formation of a strong high-pressure system above the Arctic Circle, leading to a split in the polar vortex. The upper western winds are the ones that contain the polar masses in the North Pole, and as a result of their weakness, they are unable to contain the polar air and keep it in its original home (the North Pole).

 

What are the implications of the polar vortex splitting on global weather patterns?

The split affects the polar vortex, causing changes in the distribution patterns of polar air, which directly affects the movement of jet streams and weather patterns in various regions of the northern hemisphere. The high pressure caused by this split is expected to cause the dispersion of polar air masses, thus causing a break in the polar jet stream, with expectations that polar air masses will be concentrated in the coming period over Russia and Eastern Europe, in addition to northeastern North America and Russia, where the aforementioned countries will be exposed to very cold polar waves and heavy snow.

 

Here the question arises: What about the Middle East? In this regard, the experts at the Arab Weather Center said that the arrival of polar winds to southeastern Europe, especially Turkey, will impose a significant drop in temperatures on the Levant during the period from February 20-26, 2025, i.e. the last third of the month. In terms of snow, the arrival of this polar mass to the region requires more complex snowfall systems and is under close monitoring.

And God knows best.
