The Siberian High is rebuilding: Is this a harbinger of approaching cold waves?

Experts at the Arab Weather Regional Center are monitoring the latest developments in weather maps regarding atmospheric pressure and temperatures in the lower layers of the atmosphere, with a focus on Siberia. Monitoring has shown that the Siberian Continental High has begun to rebuild itself, with atmospheric pressure reaching more than 1,040 millibars, with temperatures as low as 25 degrees Celsius below zero.

Siberian High and very cold air masses

The Siberian High accompanies a cold, dry continental air mass. With the onset of autumn, solar radiation gradually decreases in the northern regions of the globe, including Siberia, leading to rapid cooling of the Earth's surface during the night. This radiational cooling makes the air dense and heavy, and it begins to accumulate at the surface, raising atmospheric pressure and leading to the formation of the Siberian High on a large scale.

Cold winds from the Arctic further chill the air above Siberia, strengthening the high and increasing its control over the region. Although the Siberian high builds slowly in the fall, the cold, dense surface air accelerates its formation, making the high's development more stable and powerful as winter approaches.

The impact of the Siberian High on different regions

The Siberian High is one of the most important weather systems in the Northern Hemisphere during the fall and winter seasons, and it affects the climate of several large regions:

Siberia and Central Asia: The high pressure center over Siberia brings very cold and dry air.

East Asia : Includes China, Mongolia, and North and South Korea, with sharp drops in temperature due to cold northerly winds.

Japan : Heavy snowfall may occur in some western and northern regions due to the influence of polar winds on moist air coming from the Sea of Japan.

Eastern Europe: Sometimes extends into Russia, Ukraine, and Belarus, leading to very cold and dry winters.

Arabian Peninsula and the Middle East: In some cases, its influence extends to the Levant and the Arabian Peninsula, causing dry cold waves during late autumn and winter.

India: Affects the winter monsoon, resulting in cold and dry conditions, especially in northern India.

Does the formation of the Siberian High mean cold waves approaching the Arab world?

Although the Siberian High has begun to build, this does not necessarily mean that severe cold waves are approaching the Arab world. However, the chances of its expansion increase in November and December, and the chances of its extension to the Arab world remain high, climatically speaking, during the winter. The high is one of the main sources of cold continental air masses, and its climate impact, with varying periods of time, primarily affects the Northern Hemisphere.

And God knows best.
