According to the forecast of the ** Meteorological Observatory, starting from January 31, China will open the largest range of rain and snow since the beginning of winter this year, which will also be the most complicated Spring Festival weather since 2008.
The Spring Festival "collided" with a wide range of rain and snow weather, how big is the impact of this rain and snow weather process? What is the weather like in different places? What should I pay attention to on the way back to my hometown during the Spring Festival?
*The Meteorological Observatory predicts that from January 31 to February 5, there will be snowfall in the eastern part of Northwest China, North China, Northeast China, Huanghuai and other places, and there will be rain turning to sleet or snow in Jianghan, western and northern Jianghuai, northwest Hunan, central and northern Guizhou, moderate to heavy snow in most of the above areas, blizzard in some areas, local heavy snowfall or extremely heavy snowfall; There was moderate to heavy rain in most areas of the middle and lower reaches of the Yangtze River and south of the Yangtze River, and heavy rain in some areas. From February 1 to 4, there was freezing rain in parts of southern Henan, Hubei, central and northern Anhui, northern Jiangsu, southern Shandong, central and northern Hunan, and eastern Guizhou.
It can be said that this will be the most extensive rain and snow process since the beginning of winter, covering basically the entire central and eastern regions. ”**Sun Jun, chief forecaster of the Meteorological Observatorysaid that in addition to a wide range, the rain and snow weather also has the characteristics of long time and high intensity.
Sun Jun said the process is long-lasting and is expected to last from January 31 to February 5 or even 6.
Sun Jun said that the process of heavy rain and snow, the eastern part of the northwest region, North China, Northeast China, Huanghuai, Jianghan, Jianghuai, northwest Hunan, central and northern Guizhou and other places will have moderate to heavy snow, eastern and southern Shaanxi, southern Shanxi, southern Hebei, Shandong, Henan, Hubei, northwest Hunan, eastern Guizhou, eastern Liaoning, eastern Jilin and other places There will be heavy snowfall, local heavy snowfall, and even extremely heavy snowfall. Most of the above-mentioned areas have added 3 to 10 cm of snow, of which 12 to 20 cm can be reached in northwest Hubei, Henan, Shandong, eastern Liaoning, and eastern Jilin, and more than 25 cm locally.
This rain and snow process is more extensive than the southern rain and snow process that occurred around January 20, and it is also more abundant and widespread than the widespread snowfall process that occurred from December 13 to 15, 2023. There is also a certain extremity of snow cover in this process, and the snowfall in Huanghuai, southern North China and other places has a certain extremity compared with the same period in history. ”
Sun Jun introduced that due to the active plateau trough, the southern branch trough is deep, and the weather situation is high in the east and low in the west, which is conducive to the northward movement of warm and humid airflow, and at the same time, the Jianghuai cyclone will form and move to the northeast, which is conducive to the formation of a wide range of heavy rain and snow weather.
30th,"China will encounter the most complicated Spring Festival weather since 2008".The topic is on the hot search.
In this regard, Sun Jun said that the large-scale precipitation is more complicated, there is rain, snow, sleet, and even freezing rain, and it is expected that from February 1 to 4, there will be freezing rain in parts of southern Henan, Hubei, northern Anhui, central and northern Hunan, and eastern Guizhou.
According to China Weather Network, the complexity of the rain and snow process is reflected in the complex switching of precipitation phase and rain and snow transition. Judging from the current forecast, the middle and lower reaches of the Yangtze River and the south of the Yangtze River are mainly rainfall, and there is a large range of thunder and lightning activities, and the north area will experience rain and snow transformation, especially in the central and eastern parts of the country on the 3-4 days, the heavy snowfall will be very large, and there may even be heavy snowstorms locally, and there will be a wide range of freezing rain in some areas. Jianghan, western Jianghuai, western Hunan, eastern Guizhou and other places may also have frequent transitions between rain and snow, and the phase is very complex. The complexity is also reflected in the wide range of freezing rain, which will be the most in a province since this winter.
The meteorological department predicts that, overall, Henan and Shandong will be the center of heavy snowfall, and if the Jianghuai cyclone goes all the way north and is located northward, the northeast region also needs to pay attention to the heavy snowfall weather.
At present, it has entered the peak period of returning home for the Spring Festival. The Ministry of Transport predicts that 9 billion people may move during the Spring Festival this year. The total number of commercial passenger traffic such as railways, highways, waterways, and civil aviation will exceed 1.8 billion, a year-on-year increase of about 40%, and all three data will hit a record high, which can be called the "busiest" Spring Festival transportation in history.
Wang Lijuan, a senior researcher at the Public Meteorological Service Center of the China Meteorological AdministrationIt said that from January 31 to February 5, affected by heavy snowfall, Tianjin, Hebei, Shanxi, Liaoning, Shandong, Anhui, Hubei, Hunan, Henan, Sichuan, Chongqing, Shaanxi, Yunnan, ** and other places are prone to road ice and snow, high risk of traffic meteorological disasters, and the above road sections are prone to traffic congestion or traffic blockage, especially pay attention to the risk of traffic accidents in some bad weather high-impact road sections.
Wang Lijuan said that from January 31 to February 5, there was moderate snow weather along the high-speed rail in central Inner Mongolia and eastern Gansu, which had a certain impact on the operation of the high-speed railway, which may lead to train delays, and there were heavy to heavy snowfalls along the high-speed rail in central and southern Beijing, Tianjin, central and southern Hebei, southern Liaoning, central and southern Shanxi, most of Shandong, northern Anhui, Henan, central and western Hubei, central and northern Hunan, central and southern Shaanxi, etc., which had a great impact on the operation of high-speed rail, which may lead to train delays and stranded passengers at stations.
At present, it is the Spring Festival travel period, the flow of people increases, it is recommended that the public return to their hometowns or travel, do a good job of cold and warmth, anti-skid and anti-fall measures, when driving vehicles, increase vigilance, to prevent the adverse effects of snow, ice and slippery roads on traffic travel, to ensure safety. ”
Wang Lijuan said that the process of snowfall is larger, the amount of snow is also larger, may cause damage to power facilities, the power sector also needs to carry out snow removal and de-icing work in a timely manner, in advance to do a good job of energy reserves and scheduling arrangements, to ensure the stability and safety of power before and after the Spring Festival.
