12 12 two cold air streams appeared one after another. There is little precipitation and the temperature drops in most parts of China.

It is estimated that in the coming week (65438+February 12 to 18), two cold air will affect China successively, with frequent gale cooling in most parts of the north and dusty weather in North China, so the public should pay attention to protection when going out. In terms of precipitation, due to the lack of water vapor cooperation, precipitation is scarce and the weather is dry in most parts of the country.

Two cold air streams have successively affected many places in the north, and the temperature fluctuates greatly.

Three days from now, a new cold air will affect our country from west to east, which mainly affects the north. The temperature in the Yangtze River and its north will drop by 4 ~ 8℃, and the temperature drop in parts of eastern and northeastern Inner Mongolia can reach 10℃ or more. There are 5 ~ 6 northerly winds, 7 ~ 9 gusts and 65,438+in the northwest, western and northern North China, most of Inner Mongolia and Northeast China.

The cooling in various places is mostly completed in one day, and the main cooling period is 13 days. After cooling, the temperature in many places in Northeast China will hit a new low in the second half of the year. For example, Changchun and Shenyang will have the coldest day in the second half of the year at 13- 14.

After this cold air, the temperature in some parts of the north will rebound obviously at 14. However, from 15 to 17, there will be a strong cold air affecting most parts of central and eastern China. The average temperature in the eastern part of northwest China, North China, Huanghuai and most parts of the south will drop by 6 ~ 8℃, and some areas will exceed 10℃, and most areas will be accompanied by windy weather. The rebound temperature will drop quickly, and the temperature fluctuates greatly, so the public needs to increase or decrease clothes in time.

Most of China continues to suffer from drought, so North China and other places need to be alert to dusty weather.

In terms of precipitation, due to poor water vapor conditions, precipitation will remain scarce in most parts of the country in the next three days. Today, there are small to medium snow or sleet in parts of Altay, Xinjiang, western mountainous areas of southern Xinjiang basin, central and northeastern Inner Mongolia, Heilongjiang, central and eastern Jilin and eastern Liaoning. There is light rain and local moderate rain in parts of eastern Sichuan, eastern and southern Yunnan, and Taiwan Province Island.

Tomorrow, there will be small to medium snow in parts of northeastern Inner Mongolia, most of Heilongjiang, northern Xinjiang and northeastern Shandong Peninsula, among which there will be heavy snow in Altay, Xinjiang. There is light rain in most parts of Sichuan Basin, eastern and southern Yunnan, western Guizhou, eastern Guangdong, Fujian, Taiwan Province Province and other places, and there is moderate rain locally.

At the same time, in the north, due to less precipitation in the early stage of sand source and more exposed sand on the surface, the gust in some parts of western Inner Mongolia exceeded 9, the dynamic conditions for sand removal were good, and the sandstorm weather developed.

It is estimated that 12 ~ 13, there will be sand blowing or dusty weather in parts of central and western Inner Mongolia, Gansu, Ningxia, northwestern Shaanxi, central and northern Shanxi, central and northern Hebei, Beijing, Tianjin and Tarim Basin in Xinjiang, among which there will be sandstorms in western Inner Mongolia, so the public should pay attention to protection when going out.
