On December 24th, the powerful 12.25 cold air was assembled in Siberia, and the Russian Sakha Republic fell below -50 degrees. Next, they will divide the troops and sweep through the country in five days, marking an extremely cold exclamation mark for 2018. In response to this cold air, the Central Meteorological Observatory has issued a cold wave warning again.

< p> This cold wave, China's east, west, and north have a share, Hainan and Taiwan will be affected. Like Beijing, it has to "fall into the hail" and may take 3-5 minus 10 degrees (even below minus 10 degrees). This December may also be the coldest December in Beijing for more than 30 years. But in general, most of the northern part, especially Xinjiang, has already cooled down in the cold air of the winter solstice, so there is not much cooling here, and snow is not obvious.

The official forecast is that Beijing continues to be severely cold, with a minimum of -12 degrees.

Compared with the cold wave The impact on the South is even greater. Because first, this cold wave is not a flood of flooding in the south of the reservoir, but the south of the river is infiltrated by the two roads. The east road is back from the sea, and the west road leaks from the edge of the Qinghai-Tibet Plateau. Therefore, the cold wave has ample opportunity and warm and humid air. In the three hundred rounds of the war, there is plenty of time to pass through the south without a dead end.

Second, this time the cold wave south Just hit the strong warm and humid air flow that was rare in late December. On the one hand, due to the impact of the previous Qinghai-Tibet Plateau blizzard, the south branch of the “Shuiqi Tianlu” will be very deep; on the other hand, the 96W, a typhoon embryo with sufficient water content, is heading west and may be strengthened to the typhoon No. 30 near the Philippines. Cloth, together with the South Slot, will bridge the road from the ground to the height of 3,000 meters, bringing an overpass-like water vapor supply to the south.

December 25-30, the situation is based on ECMWF data

Because Therefore, this time, the South has a continuous cold, and there is a wave of rain and snow and a large cooling. It is called a dead end. According to official forecasts and the latest supercomputer model data, this time snow can go to the north of Guangdong Province in the north of Guangdong, north of Guangdong, Chengdu, Chongqing, Nanchang, Shanghai and other snowing "difficult" cities may snow or sleet; snow or ice The focus of the grain may be in Hunan Province, and Changsha may have 2-3 days of ice, snow or freezing rain. Affected by the typhoon and the cold wave, Guangdong, Guangxi, Taiwan, Hainan may have a cold and heavy rain. In the rain, the temperature in Guangzhou can approach 5 degrees, and the possibility of falling below 5 degrees after the rain stops.

ECMWF mode for Chengdu and Changsha's precipitation and temperature analysis shows that both Changsha and Chengdu may snow. Zhongqi loves production

However, because the cold wave is very slow, so the 25-26th, the south will continue to warm for two days, especially in Guangxi and Hainan, Guangdong, and may even pull out the short sleeves again. . However, after a brief warmth, the cold wave will bring about intense cooling and lasting dampness until after New Year's Day in 2019. For South China, from short sleeves to down, it may only take a few days.

Official forecast shows that temperatures in Guangzhou rise first and then fall, and as low as 6 degrees on December 30
