Arab Weather - Recent analyses at the Arab Weather Center indicated the formation of a strong high pressure system over western and southern Europe, resulting in noticeable weather stability. The high pressure system prevents the advance of cold air masses from the north of the continent, which has contributed to keeping the weather unusually stable for this time of year. The high pressure system also caused increased sunshine and temperatures to rise above their normal levels in many European cities. The high pressure system also contributes to raising pollution levels in some urban areas as a result of stagnant air.
The formation of the high-pressure system coincides with increased activity in the polar vortex, a circular atmospheric system that surrounds the North Pole and acts as a belt of cold, low-pressure air. It has regained its strength and cohesion after a period of temporary warming. This vortex is the main reason, by God’s will, behind the cold air waves that are rushing towards many areas around the world.
As a result, the chances of cold air masses rushing towards the southern and eastern regions of the European continent, including the Mediterranean region, are increasing, and thus the chances of low pressure systems forming in the Mediterranean region are increasing, and their effects on the regions vary according to the region in which the low pressure systems are formed.
Experts at the Arab Weather Center point out that transitional periods between seasons often witness rapid changes in weather systems, which affects the accuracy of forecasts in the medium and long term. Therefore, you will be provided with more details in the coming days based on computer simulation updates, God willing.
The polar vortex is a ring of cold air in the upper atmosphere that surrounds the North Pole and acts as a barrier to prevent cold air from moving south toward warmer regions. This vortex intensifies during the winter, as the Arctic gets colder, making it more compact and solid.
When the polar vortex is strong, winds swirl tightly around the North Pole, keeping cold air trapped there. But sometimes the system weakens, and cold air seeps into lower latitudes further south, causing temperatures to drop significantly.
As the polar vortex becomes more concentrated, the cold air becomes more intense and stronger, increasing the air pressure differences. This consolidation pushes cold winds toward the temperate and lower regions, generating strong cold waves accompanied by active winds that contribute to a sharp drop in temperatures.
And God knows best.
