This anticyclone will be accompanied by the influx of Arctic air masses, leading to a significant decrease in air temperature.
After a relatively warm start to winter, this phenomenon will signal the stable onset of cold weather typical of Arctic-origin air masses. A noticeable drop in temperature is also expected in Kyrgyzstan and neighboring countries, especially in mountainous areas and during nighttime. The strongest frosts are forecasted for the north.
In the northern and eastern regions of Kazakhstan, nighttime frosts of up to –30…–38 °C are expected, along with an increase in wind with gusts of up to 25–28 m/s.
Key points about the anticyclone:
Type of anticyclone
This is an Arctic (or Siberian-Arctic) anticyclone forming over the northern territories of Russia and the Arctic. Its main characteristic is cold, dry, and dense air that retains its properties for a long time as it moves southward.
Duration of frosts
Such anticyclones usually cause not short-term cold spells but persistent frosts lasting 5-10 days, especially in clear weather and with light winds at night.
Sharp nighttime frosts
Daytime temperatures may seem "acceptable"; however, nighttime and morning hours will be the coldest due to radiative cooling under clear skies.
Dangerous consequences:
- risk of hypothermia and frostbite;
- increased load on energy systems;
- likelihood of freezing of water pipes and heating networks;
- deterioration of conditions on mountain roads and passes.
Features for Central Asia
In this region, the cold may feel more intense due to the dryness of the air, even if the temperature is formally higher than in northern countries. In mountainous areas, temperature inversions may occur, where it is colder in the valleys than on the slopes.
Why New Siberian Islands are mentioned
This region often becomes a "supplier" of powerful winter anticyclones, as stable high-pressure areas form there, capable of pushing cold air far south — even to Central Asia.
