In the early morning of December 29, the temperature of the Turi River in the northeast of Inner Mongolia in China once again approached -40 degrees, and the minimum temperature was as low as -39.9 degrees, which was a new low after the final cold wave, at the same time, today there were different degrees of temperature drops in many places in northeast China, which is a sign that Siberian cold sources have invaded the northeast again.
The driving force behind all this is the Arctic vortex that has once again skimmed near the northeast of our country. At 8:00 a.m. Beijing time on December 29, the Arctic vortex center skimmed from the outer northeast north of The Heilongjiang River in China, although the center did not directly drive to the northeast of China, but still pulled the siberian cold air mass south again, making the Turi River approach -40 degrees again. Of course, from the prediction of the existing supercomputer, this Arctic vortex will not go deep south to northeast China, and the cold air mass pulling south will only be shallow, so it will not form a large-scale cold wave weather.
But on the other side of the globe, the Arctic vortex in the Western Hemisphere, it is clear that the Activity of the Arctic Vortex is about to become active, and supercomputer predictions suggest that within this week, with the violent development of high-pressure blocking high pressures in the middle and high latitudes of the Western Hemisphere, it will eventually cause a center of the Arctic vortex to fall over North America, and the accumulated cold air mass will be guided deep into the United States by a deep trough, forming a strong cold wave.
In the supercomputer's forecast, around January 2, a large amount of cold air will go south from the middle and high latitudes, taking the lead in invading the Midwest of the United States, when the 850 hPa level in some areas may appear more than 20 degrees of negative flatness, which means that some areas face a strong cooling, at the same time, the warm air in the eastern United States is extremely strong, and a huge temperature difference will be formed in the middle and low altitudes, under this temperature difference, the United States may not only face violent cooling, but also may be accompanied by strong thunderstorms, strong winds, hail, tornadoes. A series of intense weather such as blizzards.
Even many forecasts believe that this strong cold wave will reach the Gulf of Mexico and hit the warmest Florida in the southeast of the United States. As one of the cold havens in the United States, Florida, which has four seasons like summer, is generally difficult to have a positive impact of the cold wave, according to this forecast, it can not escape the strong cooling of the cold wave, and many places may be 6-8 degrees lower than the same period of the year.
Then some netizens have to ask: the earth's atmosphere is connected, will the violent fluctuations in the west wind belt spread to China? Will the intense weather in the United States be a precursor to bad weather in our country? From the current forecast, although a sub-center of the Arctic vortex will continue to circle in Eurasia, there will be more cold air affecting China in the short term, and most areas will still be warming, or do not have to worry about cold waves.
