Xinhua All Media+|Cold wave “quick freezing”: the northeast meets the blizzard and the south is cooling in many places like “season change”

Xinhua News Agency, Beijing, November 21st, by wire From 21st to 22nd, the third round of this winter’s cold wave moved eastward and southward, affecting most of my country’s central and eastern regions. The temperature will hit a new low in the second half of this year in large areas. The temperature in Jianghuai, Jiangnan and other places will drop like a “season change.” At the same time, the cold wave will also produce large-scale precipitation together with the warm and humid air, and some parts of the northeast will face blizzards. The Central Meteorological Observatory issued three early warnings on the 21st-a yellow warning for blizzards, strong winds at sea, and a blue warning for cold waves.

The Central Meteorological Observatory predicts that from 8:00 on the 21st to 8:00 on the 23rd, the temperature in most of the central and eastern regions will drop by 6℃-10℃, and East China will become a strong cooling center. Among them, the eastern part of Huanghuai, Jianghuai, and the central and eastern Jiangnan will cool down by some areas. It can reach 12°C, local 14°C or more; in most areas, there will be northerly winds of magnitude 4-6 and gusts of magnitude 7-9.

On the morning of the 23rd, the temperature in most parts of my country will drop to the lowest point of the cold wave process. The minimum temperature of 0℃ will be located in the middle and lower reaches of the Yangtze River to the northern part of the Sichuan Basin. The temperature is new low. In many places in the south, the temperature during the day is also relatively obvious, such as Jianghuai, Jiangnan and other places, the highest temperature will drop from 20 ℃ to about 10 ℃, cooling like a “seasonal change.”

At the same time, the cold southward air converged with the lower-level southerly warm and humid air currents. On the 21st, there was a large area of ​​precipitation in the southern region, including heavy rain in northern Chongqing, southern Hunan, and northern Fujian.

In the next three days, the snowfall center will be stable in the northeast. Most areas will have light to moderate snow or sleet, and some areas will have heavy snow. Among them, there will be blizzards in some areas such as eastern and northern Heilongjiang, eastern and northern Jilin, etc. There is a big blizzard or a huge blizzard (30-40 mm) on the ground.

Meteorological experts analyzed that compared with the snowfall process brought about by the last cold wave, the center of gravity of the northeast snowfall is more easterly, and the precipitation in parts of central and eastern Heilongjiang may exceed the historical extreme value during the same period. Hegang, Jiamusi and other places may experience the strongest snowfall in late November. Snowfall accompanied by strong winds will cause blizzards in some areas.

Although the cooling rate during this cold wave is not as good as the previous one (November 4th to 8th), because the base temperature was lower in the early period, it will be colder after cooling down. The current frontier of winter has advanced to Anhui and Jiangsu in the central and eastern regions. This cold wave process will also promote the winter process in the middle and lower reaches of the Yangtze River.

Experts reminded that during the cold wave, some areas in the northeast are expected to add 5-15 cm of snow, and the local area can reach more than 25 cm. The snow has not disappeared and new snow has been added. Eastern Inner Mongolia, eastern Northeast China and other places need to pay attention to the adverse effects of snowstorms on traffic, urban operations, and facility agriculture. At the same time, the temperature in most of the central and eastern regions will be significantly lower on the 22nd, especially in Jianghuai, eastern Jiangnan and southern China, and then the temperature will continue to rise again. The temperature has changed recently, and the public needs to adjust their dress in time to avoid catching a cold.
