A noticeable wave of the polar jet stream towards southeastern Europe. What is the impact of this on the Levant in the coming period?

Arab Weather - The latest weather map outputs in "Arab Weather" continue to monitor a remarkable and unusual wave of the polar jet stream in the northern hemisphere of the Earth towards the southeast of the European continent.

Weather forecasters at "Arab Weather" said that the maps of the upper layers of the atmosphere detect an unusual wave of the polar jet stream for this time of year, and the same maps also detect strong activity of the polar vortex around the Arctic Circle.

What is the impact of the jet stream wave towards southeastern Europe on the weather in the Levant in the coming period?

Experts at "Arab Weather" explain that the weather of the eastern Mediterranean basin and the Levant is closely linked to the weather systems that affect eastern and southeastern Europe. Since the polar jet stream is expected to be concentrated over eastern and southeastern Europe in the coming period, it is expected that this will lead to the approach of each colder air mass to the eastern Mediterranean basin and the Levant.

According to current data, by the end of this week, a cold air mass is expected to rush towards southeastern Europe, leading to a drop in temperatures in various regions of the Levant. However, due to the long period of time during which the accuracy of numerical models decreases, expectations are still different regarding the deepening of this air mass sufficiently towards the eastern Mediterranean basin, to form a low pressure system and rainfall in various regions. Current expectations indicate the possibility that the rush of this mass will be accompanied by a drop in temperatures and showers of rain affecting parts of the coasts of the Levant, especially Syria and Lebanon, while the effects of this cold mass are limited to a drop in temperatures in Jordan and Palestine.

What is the polar jet stream?

The polar jet stream is a belt of fast-flowing air currents, typically moving from west to east, at high altitudes in the atmosphere. It is formed by temperature differences between air masses, and plays an important role in influencing weather patterns. It travels in a wave pattern and moves at very high speeds, driven by temperature differences between cold polar air in the north and warmer tropical air in the south. The jet stream also affects weather patterns and the movement of weather systems, and its location and strength can change, affecting short-term weather conditions and even long-term climate patterns.
