CCTV***According to China Weather Network News, since February 17, the first cold wave of the Year of the Dragon has swept across most of China, and the rain and snow weather has spread from west to east. From the 21st to the 22nd, the central and eastern parts of the country will enter the strongest period of this round of rain and snow freezing process, and the precipitation phase in Henan, Hubei and other places is complex, and rain, snow and freezing rain coexist. Around the 23rd, a new round of rain and snow freezing will be seamless, and freezing rain in some areas such as Hubei and Hunan may last for 4 to 6 days. Now that we are returning from the Spring Festival, two consecutive rounds of rain, snow and ice will adversely affect traffic travel in which areas? China's Weather**Don't launch a rain and snow calendar for the return trip to big cities during the Spring Festival to see when and where the impact is most severe.
The first cold wave of the Year of the Dragon has affected nearly 20 provinces, and a new round of rain, snow and ice has come again around the 23rd
As of today (February 20), the impact of the first cold wave of the Year of the Dragon has lasted for four days, and a wide range of rain and snow have affected nearly 20 provinces, autonomous regions and cities such as Xinjiang, Gansu, Inner Mongolia, Shandong, Shanxi, Henan, and Jiangsu, which has had a great impact on the return of the Spring Festival, and many high-speed sections and toll stations have been closed.
According to China Road Network Weibo, as of 10 o'clock today, affected by snowfall and road ice, Hebei, Shanxi, Inner Mongolia, Jilin, Heilongjiang, Shandong, Anhui, Henan, Shaanxi, Gansu, Xinjiang A total of 16 road sections were closed, and 371 toll stations were closed.
Shi Yan, a meteorological analyst at China Weather Network, said that from the 21st to the 22nd, as the main body of the cold wave moves south, the scope and intensity of rain and snow in the central and eastern parts will reach its peak, and the snow line will be pressed south to the Yangtze River, and there will be heavy snowfall in some areas of Shanxi, Shandong, Henan, Hubei and other places. At the same time, the precipitation phase in some areas of Huanghuai, Jianghuai and other places will change, and some areas such as Henan, Shandong, Anhui, and Hubei will have frozen rain or ice particles. To this end, **The Meteorological Observatory has issued a Blue Warning for Heavy Snow and a Yellow Warning for Freezing this morning.
At the same time, in the process of the cold wave moving southward, it will also encounter a strong confrontation of warm and humid airflow, which will stimulate a large amount of unstable energy, bringing strong convective weather to Jiangnan and South China, and Anhui, Hubei, Hunan, Jiangxi, Guizhou, Guangxi and other places will have short-term heavy precipitation accompanied by hail.
After the end of the cold wave process, there will be supplementary cold air southward to affect our country, and from the 23rd to the 26th, the new first range of rain, snow and freezing weather will be seamless. At that time, the southernmost part of the snow line may cross the Yangtze River, and the precipitation phase of many provinces along the Yangtze River is very complicated, and some areas in Hubei, Hunan, Guizhou and other places will encounter rain, freezing rain, sleet and pure snow.
The rain and snow calendar of big cities on the return trip of the Spring Festival is released, and there will be freezing rain in Wuhan, Changsha and other places
Judging from the rain and snow calendar of the return city of the Spring Festival launched by China Weather Network, in the coming week, in the areas north of the Yangtze River, such as Xi'an, Zhengzhou, Hefei and other places, snow will be the mainstay, and the snowfall period will be mainly concentrated from the 21st to the 24th. Hefei snowfall is the most obvious, and it may be hit by heavy snow on the 22nd.
In the area south of the Yangtze River, the precipitation phase is more complex, and precipitation in Changsha and Wuhan may be seen every day. Among them, there will be freezing rain in Wuhan from the 21st to the 22nd, turning to moderate snow on the 23rd, and freezing rain on the day of the Lantern Festival. Freezing rain in Changsha lasts the longest, up to five days. Nanchang will be dominated by rain, and there will be rain in five of the next six days, of which the rain will be heavier on the 21st, or it will rain heavily.
In general, although the intensity of the freezing rain process from the 21st to the 26th was not as strong as that before the Spring Festival, the scope and duration of the impact were comparable, especially in southern Hubei and northern Hunan, where the freezing rain may last from the 21st to the 25th. Once the road surface is icy, it is more difficult to remove than snow, so it is important for the local authorities to prepare for de-icing and melting in advance.
China Weather Network reminds that until around the Lantern Festival, a wide range of rain, snow and freezing weather will cover most of China, including some areas in the south of the precipitation phase is complex, the public must pay attention to the latest warnings and forecasts issued by the meteorological department and the latest information released by relevant departments such as highways, railways, airports, etc., and plan travel reasonably. In addition, the temperature in many places in the south continues to be low, and the public still needs to do a good job of cold protection and warmth.
