The Siberian high continues to grow as winter approaches, and is the main cause of severe cold waves.

Arab Weather - Winter begins in terms of the meteorological calendar at the beginning of December 2024, which is the unofficial beginning of winter. With the meteorological entry of winter, the results of the numerical computer outputs indicate the continued growth of the Siberian high over northern Asia, specifically Siberia. The Siberian high is one of the most prominent causes of the dry cold waves that the region is exposed to, and its intensification in the coming months is statistically linked to the growth of the La Niña phenomenon.

The Siberian high will strengthen in the coming months and is the main cause of dry cold waves.

In detail, the Siberian system is considered one of the most important sources of cold continental air masses, especially the continental polar air masses. Although the Siberian high has begun to form, it does not cause severe cold waves except in the areas it controls. Its development does not necessarily mean that cold waves are close to the Arab world. However, the Siberian high affects the climate at different time periods mainly in several wide geographical areas during the fall and winter seasons.

In some cases, the influence of the Siberian High extends to areas of the Middle East during some periods, especially at the end of autumn and winter, including the Levant and the Arabian Peninsula. This leads to dry cold waves, causing a significant drop in temperatures as expected next week.

Strengthening of the Siberian High is statistically linked to the development of the La Niña phenomenon

The eastern tropical region of the Pacific Ocean has recently witnessed a negative anomaly in surface water temperatures, as the water temperature is cooler than average by between one and a half and two degrees, which means the development of the La Nina phenomenon. Arab Weather forecasters believe that the La Nina phenomenon is statistically linked to the intensification of the Siberian High's influence on the Arabian Peninsula and the Levant during the winter.

And God knows best.
