Since February, the strongest rain and snow since 2009 has swept through the central and eastern parts of China, which has had a great impact on the Spring Festival travel, and the meteorological observatory has continued to issue warnings of heavy snow, freezing, and strong winds.
How bad is this round of rain, snow and freezing weather? Will the rain, snow and freezing weather continue in the later period?
Zhang Hengde, deputy director of the National Meteorological Center, said on February 7 that it is expected that during the Spring Festival holiday, the temperature in most parts of the country will rise first and then fall, and the average temperature will be higher than that of the same period in normal years. There is no widespread rain, snow and ice, persistent fog, haze and other disastrous weather.
According to the statistics of the China Meteorological Administration, since January 31, a wide range of rain, snow and freezing weather that lasted for nearly six days has affected the central and eastern regions, affecting 18 provinces and affecting more than 2.5 million square kilometers of land area.
*According to experts from the Meteorological Observatory, the rain, snow and freezing weather process was triggered by the combination of sufficient water vapor brought by the south-branch trough that moved eastward and deepened and cold air in the middle and high latitudes of the north. In the meantime, the Jianghuai cyclone exacerbated the intensity of snowfall, making theFebruary 3 and 4 became the heaviest snowfall periods of the event
Due to the confrontation between cold air and warm and humid airflow, resulting in a long period of complex rain and snow weather, southern Henan, northern Jiangsu and Anhui, Hubei, northern Hunan, Guizhou and other places have experienced repeated changes in precipitation phases such as sleet, rain to snow, snow and freezing rain.
Among them,Widespread freezing rain occurred in central and eastern Guizhou, central and northern Hunan, central and eastern Hubei, central Anhui, and southeastern HenanWith a total area of more than 300,000 square kilometers, the scope and intensity of freezing rain are the strongest since 2009. According to statistics, more than 50 national meteorological observation stations in the central and eastern regions have experienced more than 3 days of freezing rain, of which the number of freezing rain days in Jingmen, Zhongxiang, Yunmeng and other places in Hubei Province is as high as 4 days.
Freezing rain is often accompanied by low temperatures, which not only brings the risk of ice accumulation on the road surface and tracks, but also damages the railway power grid and affects the normal operation of the railway. During this process, ice accumulation occurred in eastern Hubei, northern Hunan, eastern Guizhou and other places.
As of 17:00 on February 5,A total of 75 counties (cities and districts) in Hunan experienced low temperature, rain, snow and freezing weatherThere are 6 counties (cities, districts) where the ice accumulation of power lines exceeds 10 mm, and the maximum thickness of power line ice accumulation is 18 mm (Dongting Lake). According to ** reports, affected by freezing rain, many trees on the streets of Wuhan were crushed by ice and broke their branches.
The monitoring shows that the rain, snow and freezing weather in this range lasts for a long time, the rain and snow intensity is high, and the snow depth is deep, which has different degrees of impact on the railway, shipping, highway and other transportation during the Spring Festival.
Monitoring shows that as of 8 o'clock on February 5, the maximum snow depth of 144 national meteorological observation stations in the central and eastern regions reached more than 10 centimeters during this round. Among them, the snow depth in Qianjiang in Hubei Province reached 20 cm, and the snow depth in Huoqiu in Anhui Province reached 23 cm, breaking the snow depth record in February since local records began. The maximum snow depth in five places, including Hongze in Jiangsu, exceeded the extreme value of the same period in February since 2009.
Affected by long-term rain, snow and freezing weather, many transportation hubs such as Wuhan, Chengdu and Shenzhen have been suspended or delayed.
On February 3rd and 4th, the rain, snow and freezing weather in this ** range entered its heyday. According to the statistics of the transportation department, affected by bad weather, from February 4 to 5, hundreds of trains on the Beijing-Guangzhou high-speed railway and the Han-10 high-speed railway under the jurisdiction of the Wuhan Railway Bureau continued to be suspended and delayed, and a large number of passengers were stranded at many stations such as Guangzhou, Wuhan and Wuchang stations.
In terms of shipping, on the 4th, a large number of flights were canceled at Wuhan Airport throughout the day, and the operation efficiency of Hefei Airport was low throughout the day. In terms of highways, as of 12 o'clock on the 5th, a total of 76 highway sections in Hubei, Hunan, Henan, Anhui, Guizhou, Jiangsu, Jiangxi, Guangdong and other places were closed due to rain, snow and freezing weather, of which 39 were closed in Hubei. Some netizens reported that they were trapped on the highway for 10 hours on the way home.
On the 6th, the Ministry of Finance and the Ministry of Transport issued an emergency 14.1 billion yuan will be used to support 11 provinces (municipalities) such as Hunan, Hubei, Guizhou, and Chongqing to carry out highway ice and snow removal, diversion and other rush and traffic protection work, and make every effort to ensure the safety and smoothness of the Spring Festival highway.
The Office of the National Disaster Prevention, Mitigation and Relief Committee and the Ministry of Emergency Management have launched a national four-level disaster relief emergency response in response to the impact of the recent low-temperature, rain, snow and freezing disasters on Hubei and Hunan. The Office of the National Committee for Disaster Prevention, Mitigation and Relief sent three working groups to assist and guide the frontline in Hubei, Hunan and Anhui.
Zhou Wei, Emergency Command Commissioner of the Disaster Relief Department of the Ministry of Emergency ManagementAccording to the introduction, we will increase the coordination and disposal efforts, comprehensively carry out the work of clearing snow and ice, and effectively ensure the livelihood of people stranded on the road. Continue to do a good job in the inspection of transmission lines and the observation of icing, and take timely measures to remove and melt ice. Pay close attention to repairing faults and restore normal power supply. Strengthen the safety management of temporary buildings and construction sheds, pay close attention to the risk of geological disasters caused by continuous heavy rainfall, and resolutely and decisively evacuate the threatened people. Next, in combination with the disaster situation, we will work with relevant departments to allocate disaster relief funds and materials in a timely manner, and do a good job in disaster relief and relief work in an efficient and orderly manner.
On February 7, a wide range of rain and snow in the south continued, with heavy snow in parts of central and southern Hunan, southwest Jiangxi and other places, and local blizzards, with a cumulative snowfall of 5 to 18 mm in some of the above areas, and more than 20 mm locally, with a new snow depth of 3 to 10 cm and more than 18 cm locally. There was freezing rain in parts of central and eastern Guizhou, most of Hunan, northwestern mountainous areas of Jiangxi, mountainous areas of southern Anhui, and mountainous areas of western Zhejiang.
Meteorological experts remind,On the 7th, there was still strong rain, snow and freezing weather in Hubei, Hunan, Jiangxi and other places, and the temperature continued to be low, which was not conducive to snow and ice melting。It is recommended that the public pay close attention to the latest forecast and warning issued by the meteorological department and the latest road condition information released by the transportation department before traveling, plan their travel reasonably, and prevent the adverse impact of road ice on traffic travel; At the same time, do a good job of cold protection and warmth, and pay attention to the safety of electricity, gas and fire.
* Forecast by the Meteorological ObservatoryStarting on the 8th, the rain and snow in the south will begin to weaken, and by Chinese New Year's Eve, the precipitation in the south will basically end, and the sky will be clearMost parts of the country will welcome the Spring Festival with fine weather, and a wide range of fine weather will last for 4 to 5 days.
