Starting from January 31, the central and eastern regions of China will encounter the largest and longest rain and snow weather process since this winter, and China will encounter the most complicated Spring Festival weather since 2008. According to meteorological experts, 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. From the perspective of the time period, the impact of rain and snow will be from the middle and late part of this week to the beginning of next week, which is the critical period of the Spring Festival. "News 1+1" connects Xu Jun, chief forecaster of the ** Meteorological Observatory, and Wang Lijuan, an expert from the Public Meteorological Service Center of the China Meteorological Administration, to jointly pay attention to: How to ensure the Spring Festival transportation in a wide range of heavy rain and snow weather?
Widespread rain and snow are coming, how to deal with it?
Starting from January 31, the central and eastern regions of China will encounter the largest and longest rain and snow weather process since this winter. Bad weather has always tested traffic safety. Especially at present, it is the critical period of the Spring Festival, and Hubei, Henan and other important transportation hubs connecting China's north, south, east and west, are also in the core impact area of this rain and snow. What preparations are being made? And how to deal with this rain and snow?
In many places, the daily or cumulative precipitation is extreme
*Xu Jun, Chief Forecaster of the Meteorological Observatory: Generally speaking, extremity generally refers to approaching, reaching or exceeding historical extremes or extremes in the same period, and the historical period generally refers to sufficient observation data for decades. In this rain and snow process, we are talking about the extremity of the same period in early February, which means that the daily precipitation or cumulative precipitation in this process may be close to or exceed the maximum value that occurred in early February in history. In this process, the snowfall in southern Shaanxi, southern North China, northern Huanghuai, Hubei, northern Chongqing, eastern Liaoning, eastern Jilin and other places can reach 10-25 mm, and locally exceed 30 mm; The new snow cover in some of the above-mentioned areas can reach 10-20 cm, and the local snow can exceed 25 cm, which is extreme. This is a relatively rare rain and snow weather process, with high snowfall intensity, long duration, and high cumulative heavy snowfall intensity, which will have a greater impact on Spring Festival travel.
Will there be a rain, snow and ice disaster similar to 2008 this year?
*Chief forecaster of the Meteorological Observatory Xu Jun: I don't think so. Compared to 2008, there are two differences this time, the first is the 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 point is reflected in the low temperature, 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. In addition, after 15 years, we have improved our ability to respond to such extreme disasters. So, in summary, we don't think there will be an extreme disaster like 2008 this time.
How can local departments respond?
Wang Lijuan, an expert from the Public Meteorological Service Center of the China Meteorological Administration: This large-scale rain, snow and freezing weather will have a significant impact on traffic security, energy supply and facility agriculture. Due to the serious impact of rain, snow and ice, most of the areas are in the central and eastern transportation hub provinces, such as many high-speed railways such as Tujingnan and Zhengzhou, and many expressways such as Daguang, Beijing, Hong Kong and Macao. Affected by freezing rain and snow, the risk of ice and snow cover of power facilities in Jianghan and Jianghuai will increase, and the electricity heating load in the south may increase. Therefore, the energy and power sector needs to prepare energy reserves and snow and ice removal in advance. In addition, facility agriculture in the north should also pay attention to the timely clearing of snow in the arch shed. In general, the transportation, power energy, oil and gas security, as well as agricultural production departments in most of the central and eastern regions, need to pay attention to local rain and snow changes in a timely manner, and do a good job of prevention and response in a timely manner.
What should the public pay attention to when traveling?
Wang Lijuan, an expert from the Public Meteorological Service Center of the China Meteorological Administration: The severe impact of the rain, snow and freezing process overlaps with the peak period of Spring Festival travel, which will have a greater impact on road, railway, and air travel. Blockages such as road blockages, rail delays, and flight delays will bring a lot of uncertainty to the public's travel time. Therefore, when you travel, on the one hand, you should pay attention to the cold and keep warm, beware of colds, and on the other hand, you must make a good time arrangement. In addition, because there is a great feature of this year's Spring Festival, that is, the proportion of inter-provincial travel and self-driving travel has increased significantly, so the public who travel by car should pay special attention to preventing snow, ice and slippery roads to prevent traffic accidents. In addition, the meteorological department will issue the latest forecast and warning in a timely manner for this process, because the duration is relatively long, and the scope of influence is relatively wide, so it is recommended that the public should pay close attention to the changes in weather and traffic information at the place of travel, the place of passage and the destination to ensure the safety of travel.
