The Russian polar vortex is a positive indicator of the approaching winter weather in the region, and numerical models monitor its development later

Arab Weather - The weather forecasting staff at the "Arab Weather" Center is following repeated indicators of the rapid growth of the polar vortex and its move to the Russian side later in the beginning of next November.

Weather forecasters at Arab Weather said that the growth of the Russian polar vortex is statistically linked to the possibility of the polar jet stream deepening later to southeast Europe and approaching the eastern Mediterranean basin, which portends the approach of the closest winter weather and perhaps an increase in the possibility of the Kingdom being affected by cases of atmospheric instability and perhaps early air depressions later at the end of this month and the beginning of November.

Returning to the statistical data in "Arab Weather", it shows an early wave of the polar jet stream towards the southeast of the European continent at this time of year, as the region witnessed during the past few days an early cold wave in which Jordan and parts of the eastern Mediterranean basin recorded temperatures that it had not witnessed in October for 21 years, which gives us an initial indication of the recurrence of such weather systems in the coming winter season and the renewal of cold waves in the region, God willing.
