China Weather Network News Yesterday (January 17), as the current cold wave is coming to an end, the temperature in the northern region has begun to embark on a "recovery path", and starting today, all parts of the south will gradually enter the "recovery channel". It will generally rise to a relatively high level.

However, this week, as the weather returns to calm, the fog and haze in North China, Huanghuai and Huai will be "excellent." It is expected that the above areas will experience light to moderate haze from tomorrow.

The south of the Yangtze River joins the "Recovery Army" today

　　Since January 14, another cold wave has struck. Most areas of our country have experienced strong winds and a cooling process. Yesterday, the impact of the cold wave was nearing its end. The area north of the Yangtze River has begun to fully warm up, but the temperature south of the Yangtze River is still continuing. Down.

According to live monitoring, at 05:00 today compared to 05:00 yesterday, Jiangxi, Fujian, central and eastern Guangxi, Guangdong, northern central Hainan, central and northern Sichuan, and eastern Yunnan experienced 6-10°C drop in temperature.

　　Today, the south of the Yangtze River will also formally enter the "warming channel", and temperatures in various places have begun to rise in an all-round way.

It is understood that the cold wave is cooling down quickly, but the temperature rise after the cold wave is also very fast. The temperature in most parts of the country will return to normal or even high levels within a day or two. For example, the highest temperature in Hangzhou yesterday was only about 7°C. , It will be able to return to 12℃ today, and it will return to 17℃ by the 20th.

　　However, Northeast China and North China will be affected by the eastward shift of the cold vortex trough today and tomorrow, and the temperature will still fluctuate significantly. For example, in Shenyang, the highest temperature yesterday was around -5°C, and today it will drop to -12°C again. It can be said that the ups and downs are very obvious when it rises to 3°C.

　　It is worth mentioning that after the end of the cold wave, the weather in most parts of my country will enter a quiet and stable state. The atmospheric diffusion conditions in North China and the Huanghuai area will gradually deteriorate, and the haze will be disturbed in the future. It is expected to start tomorrow. Light to moderate haze may occur, and public travel needs to pay attention to protection.

Most of the country's rain is scarce and southern regions will welcome large-scale precipitation after 20 days

　　In terms of precipitation, since yesterday, most areas of my country have been scarce in precipitation, and this pattern will continue to be maintained today and tomorrow.

The most concentrated area of ​​precipitation is still in the southwest. It is estimated that from 08:00 today to 08:00 tomorrow, there will be light to moderate snow in parts of eastern Inner Mongolia, northeast China, southeast Heilongjiang, eastern Jilin, eastern Tibet, southern Qinghai, etc. Among them, there was heavy snow in the eastern part of Tibet.

There were showers or light rain in parts of western Yunnan and other places.

　　However, after January 20, my country's southern region will once again usher in a large-scale precipitation process.

It is expected that from January 20 to 23, there will be moderate to heavy rain in parts of the eastern and southern parts of Southwest China, eastern Jianghan, Jiangnan, and central and eastern South China; parts of the southeastern part of Northwest China, western Jianghan, Huanghuai and other places successively There will be light to moderate rain (snow) or sleet, and heavy snow will also appear locally in high altitude areas.

　　It is understood that the recent rainfall in southern China, southern Jiangnan and central and southern Yunnan has continued to be low, droughts have continued to develop, and severe droughts have occurred in some areas. For example, the last effective precipitation (precipitation of 0.1 mm or more) in Shenzhen, Zhuhai, etc. Dating back to late November, there was almost no rain for more than a month and a half.

The large-scale precipitation process that began in the south 20 days later will be more beneficial to alleviating drought conditions and reducing forest fire risk levels in southwestern and southern China.
