In the coming daysi the frosts that affect Siberia will tend to spread to most of central and southern Asia even involving the northern sectors of Nepal, Pakistan and Afghanistan as well. But the cold breath will be felt in eastern China, Korea and Japan. Along with this situation the Siberian anticyclone will tend to move south dragging the frozen mass of air with it. According to forecasts, the pressure on the ground of the anticyclone, on December 28, should reach values close to 1070 hPa if not higher between Mongolia and China. The record for the highest pressure recorded is 1086 hPa, again in Mongolia in 2011. These values are due to the weight of the frozen air mass that characterizes thermal anticyclones. In addition to the pressure well above the climatological average, the extension will also characterize the anticyclone. Low temperatures can be a problem; in Mongolia, the ‘dzud’ indicates a particularly snowy winter in which animals cannot find forage for snow.
Although SIBERIAN HIGH has ‘regional’ effects since it operates mainly in development areas, this event could influence atmospheric circulation in early 2021. The particular arrangement of the pressures that are formed along the Himalayas induces the conservation of angular momentum. a sharp rise in the Asian jet stream. The transport of energy from the bottom up also leads to a heating of the polar stratosphere on the one hand, on the other, it can affect the circulation between Asia and North America. It seems likely that the ASIAN FORTE MOUNTAIN POSITIVE TORQUE that will develop at the end of the month can affect the weakening beyond the polar vortex and, in the case, on the split of the stratospheric.
