**The Meteorological Observatory predicts that from today (January 31) to February 5, the central and eastern regions of China will experience the largest and longest rain and snow weather process since this winterIt will also be the most complicated Spring Festival weather since 2009
Accumulated rain and snow are heavy and snow is thick. Shaanxi, central and southern Shanxi, southern Hebei, Henan, Shandong, Hubei, northern and eastern Chongqing, eastern Liaoning, eastern Jilin and other places can reach snowfall10 25 mm, locally exceeded30 mm；New snow cover in northern and eastern Chongqing, northwest Hubei, southern Henan, central and northern Shandong, and eastern Liaoning can be reached10 20 cm, local can be exceeded25 cm
The freezing rain covers a wide range of provinces and many provinces. From February 1 to 4, there was freezing rain in parts of southern Henan, central and western Hubei, northern Anhui, northern Jiangsu, southern Shandong, northwest Hunan, eastern Guizhou, and eastern Chongqing.
The phase transition of rain and snow is complex. After the process began, there was sleet or rain turning to snow in southern Shaanxi, southern Shanxi, Henan, southern Shandong, central and northern Jiangsu, central and northern Anhui, Hubei, northern Hunan and other places, and in the afternoon of January 31, Shaanxi and Shanxi turned to snow; On the night of the 31st, snow turned in the northern part of Henan and the southern part of Shandong; On the afternoon of February 1, snow turned in most of the above-mentioned areas.
The process lasts for a long time. The duration of this rain and snow process is:6 daysShaanxi, Shanxi, Shandong, Henan, Jiangsu, Anhui and other places rain and snow last for 4 5 days, and the rainy weather in some areas of the middle and lower reaches of the Yangtze River can reach 6 daysThe process also lasted the longest since 2009
Many places broke the extreme value of the same period. The cumulative precipitation in parts of southern Shaanxi, southern Shanxi, southern Hebei, Henan, Shandong, Jiangsu, Anhui, Hubei, northern Chongqing, northern Jiangxi, and northern Hunan will approach or exceed the extreme value of the same period in history.
Widespread rain, snow and ice are superimposed on the peak of returning home
It is necessary to be vigilant against risks and strengthen responses
According to statistics, during the 40-day Spring Festival this year, the cross-regional flow of people across the country is expected to reach 9 billion, a record high. Among them, there were about 7.2 billion self-driving passengers, and about 1.8 billion commercial passengers by railway, highway, water transport and civil aviation.
this processThe duration, low temperature intensity, and freezing range were not as good as those in the early 2008 low temperature rain and snow freezing process in southern ChinaThe cold degree is not as good as the "overlord" cold wave at the beginning of 2016, and even less than the cold wave process from January 21 to 23 just past, but the overall location of the snowfall and freezing area in this process is northerly, and the rainfall in the middle and lower reaches of the Yangtze River and the south is obvious, and its power is still not to be underestimated.
The impact period of rain and snow overlaps with the peak of returning home, and the severe impact areas are mostly in the central and eastern transportation hub provinces. The impact range of freezing rain is large, and there is great harm to the operation of highways, railways and flights. Severe convective weather such as thunder and lightning can also be catastrophic.
Meteorological experts remind,Rain, snow and freezing weather have a heavy impact on railways, highways and aviation, and snow, ice and low visibility on roads can easily lead to traffic congestion or accidents on highwaysIt is recommended that the public pay close attention to the weather forecast and warning at the origin, destination and along the route and the road condition information released by the transportation department to ensure travel safety.

What are the characteristics of this widespread rain and snow?
Meteorological experts introduced,The rain and snow weather process has the characteristics of wide rain and snow coverage, long duration, large range of freezing rain, and extreme cumulative precipitation in some areas
Last night (30th), the main station's "News 1+1" connected with Xu Jun, the chief forecaster of the ** meteorological station. Xu Jun introduced that extremity generally refers to approaching, reaching or exceeding historical extremes or extremes in the same period, and historical periods generally refer to data observed for decades. The daily precipitation or cumulative precipitation during this rain and snow process is likely to approach or exceed the maximum value recorded in early February.
Xu Jun said that this is a relatively rare rain and snow weather process, with high single-day snowfall intensity, long duration, and heavy cumulative snowfall intensity, which will also have a greater impact on Spring Festival travel.
Will there be a rain, snow and ice disaster similar to 2008 this year?
Xu Jun introduced,This year, there will be no rain, snow and ice disasters similar to those in 2008。Compared with 2008, this rain and snow process has the following differences:
The first is duration. The 2008 cold rain and snow freezing weather lasted for nearly a month, and this rain and snow process lasted less than a week, and the cumulative snow was not as large as in 2008. In terms of the scope and intensity of the ice, it is also less than that in 2008.
The second is reflected in low temperatures. Because 2008 was a low-temperature rain and snow freeze, and this time it was a rain and snow freezing process. The low temperature in 2008 was mainly low in the southern region, and the temperature in most parts of the southern region was 4 to 6 lower than that in the same period of the year.
Finally, in terms of forecasting, the ability to respond to such extreme disasters has been improved.
How to prevent freezing rain?
Personal travel: In freezing and rainy weather, the temperature is low, pay attention to cold protection and keep warm, especially the elderly, children and people with weak constitution should try to go out as much as possible. Due to the icy and slippery road surface, take anti-skid measures when going out, and pay attention to stay away from or avoid motor vehicles and electric vehicles.
Transportation: The driver should drive cautiously, do not overtake, accelerate, make sharp turns or emergency braking, and install tire snow chains in time; Bridges, ventilation intersections, slopes and other dangerous road sections that are easy to freeze and slip should be fully prepared with anti-skid sand, industrial salt and other rescue materials; Actively carry out the work of salt and de-icing on roads.
AgricultureFor some farmland seedlings, it is best to pull up a plastic shed or cover and insulate to avoid direct contact with freezing rain; The branches of fruit trees should be wrapped in plastic film in time to prevent a large amount of freezing.
Power communicationsStrengthen the repair and maintenance of wires, wires and towers, and scrape off the ice attached to them in a timely manner; Strengthen the inspection of key hidden dangers of freezing rain and snow poles and roads and the presence of rusty hanging lines; Strengthen the inspection of base stations in densely populated areas and important traffic roads to prevent base stations from tilting or collapsing due to snow and ice.
