Does the Siberian Highlands affect Saudi Arabia’s winter weather?

Arabia Weather - The Siberian High Pressure System is the largest and most influential high-pressure system during the winter of the Northern Hemisphere, as it is centered at 45 degrees north latitude, over northeastern Siberia and central Asia. The Siberian High is considered responsible for the severe and dry cold waves in large areas of Europe and Asia.

The decrease in land temperature in winter leads to an increase in the strength of the Siberian High, and its extension southward to cover the region of southwest Asia, forming a system of high pressure extending from the plateau of Armenia, Anatolia, and northern Iraq.

The Siberian High expands to affect the northern Arabian Peninsula superficially in winter, pushing cold, dry northeasterly winds towards Saudi Arabia. This is clearly evident in the increasing coldness of the atmosphere in the Saudi regions, especially at night, forming waves of frost in large areas of the Kingdom.

What is the impact of the Siberian Ridge on instability in the Kingdom of Saudi Arabia?

The tropical current is sometimes active in the winter on the Arabian Peninsula, especially in the years in which the “El Nino” phenomenon dominates. This leads to the push of warm, humid currents from the Arabian Sea in the high layers of the atmosphere towards the Kingdom. The rush of these warm currents may coincide with the expansion of the Siberian High. Surface to the Kingdom and large thermal differences arise, leading to the formation of cases of atmospheric instability in the region.
