Four early warnings are issued! Cold wave+blizzard+strong wind+strong convection, the temperature will drop by 16℃

　　In the next few days, the cold wave will gradually move south, from west to east and from north to south, gradually affecting most parts of China.

　　△ On November 4th, the impact of the cold wave has been highlighted, with cooling in Xinjiang and Inner Mongolia.

　　With the penetration of cold air, the temperature in most parts of the north to the middle and lower reaches of the Yangtze River will hit a new low after autumn, and the situation of abnormally high temperature in the previous period will also change, and the temperature in eastern Inner Mongolia and northeast China will be reversed from significantly high to low.

　　△ National temperature anomaly in the past ten days VS temperature anomaly in the next ten days. From warm to cold.

　　On the evening of the 4 th,The Central Meteorological Observatory issued four early warnings of cold wave, blizzard, strong wind and strong convection.!

　　It is estimated that from 20: 00 on the 4th to 20: 00 on the 7th, the temperature will drop by 6 ~ 10℃ in the central and eastern parts of northwest China,The temperature in central and eastern Inner Mongolia, south-central Northeast China, central and eastern Jianghuai and other places will drop by 12 ~ 14℃, and the local temperature drop in southwestern Jilin, northwestern Liaoning and southeastern Inner Mongolia will reach more than 16℃.; The lowest temperature appeared on the morning of the 7th, and the lowest temperature 0℃ line will be located in northern Hebei, southern Beijing, southwestern Shanxi, Guanzhong Plain in Shaanxi and southeastern Gansu, and the lowest temperature in most areas along the Yangtze River will drop to about 10℃. There are 4 ~ 6 northerly winds in the north of the middle and lower reaches of the Yangtze River, and the gusts are 7 ~ 9, and the local level can reach 10.

　　The temperature drop is most severe in Northeast China, especially in Jilin, where the drop is generally above 16℃. The highest temperature in Changchun will be 11℃ tomorrow, and it will drop to -5℃ on the 7th, with a cumulative drop of 16℃.

　　The cooling in the middle and lower reaches of the Yangtze River is also very intense. The highest temperature in Shanghai, Hangzhou and other cities is still around 30℃ on the 4th and 5th. In particular, the highest temperature in Hangzhou will reach 31℃ tomorrow, but it will drop to 19℃ on the 6th, and seasonal and cliff-like cooling will be staged.

　　Moreover, this cold wave is still an effort. Although it is a "spent force" to go to Guangdong, it will still cool down Guangdong and send some coolness ~

　　In addition to strong winds and cooling, the cold wave will also bring a wide range of rain and snow weather to China. It is estimated that from 20: 00 on the 4 th to 20: 00 on the 6 th,There have been heavy snowstorms from west to east in the central and eastern Inner Mongolia, the central and western parts of Northeast China and the north, and there have been heavy snowstorms in some areas and local heavy snowstorms.(30 ~ 34 mm), the new snow depth is 10 ~ 20 cm, and the local area can reach more than 25 cm. The main snowfall period is from the night of the 5th to the 6th.

　　The precipitation in the east and northeast of Inner Mongolia lasts for a long time, and the accumulated precipitation is large, and the precipitation phase is complex. In the early stage, the temperature is high before the rain snows, and the snow will turn from tomorrow night to the day after tomorrow, accompanied by strong winds, and there will be snowstorms in some areas, which is extremely extreme.

　　Why is the snowfall in Northeast China so strong this time? Zhang Juan, a meteorologist of China Weather Network, said that there was a cold vortex at high altitude and the ground cooperated with cyclones, which made the water vapor in the Yellow Sea and the Sea of Japan rise strongly after being involved. The snowfall intensity was rare in early November.

　　Remember the rain and snow process in early November 2021? The daily precipitation of 151 national stations in Northeast China, Inner Mongolia, North China and Huanghuai broke the historical extreme in November. The phase transition of rain and snow in Northeast China is complex, and freezing rain occurs. The snow depth in Inner Mongolia, Jilin and Liaoning is more than 40 cm.

　　Although the scope of rain and snow in Northeast China is not as wide as that in 2021, there will still be rain and snow conversion, and the snow potential is relatively strong.

　　In addition, the Central Meteorological Observatory issued a strong convective warning on the evening of the 4th. It is estimated that from 20: 00 on the 4 th to 20: 00 on the 5 th, there will be 8-10 thunderstorms or hail weather in parts of southern Anhui, south-central Hunan, north-central Jiangxi, southern Guizhou and northwestern Guangxi; There will be short-term heavy precipitation in parts of central and southern Anhui, eastern Hubei, most of Hunan, central and northern Jiangxi, southeastern Chongqing, eastern and southern Guizhou, northwestern Guangxi, southwestern Guangdong, Hainan Island and other places, with a maximum hourly rainfall of 20-30 mm and a local area of more than 50 mm.

　　The heavy snowfall in Inner Mongolia, Heilongjiang, Jilin and Liaoning, coupled with the superposition effect of previous snowfall, has a medium and high risk of snowstorm and low-temperature rain, snow and freezing disasters. Relevant departments and the public should pay attention to the traffic congestion or accidents that may be caused by snow and ice on road sections, and agriculture and animal husbandry should pay attention to the possible adverse effects of heavy snowfall; Strong convection and strong cooling in the south are coming, and the public should also pay attention to prevention.
