From January 31 to February 5, the heaviest winter rain, snow and freezing weather since 2009 affected the central and eastern parts of China. **The Meteorological Observatory will continue to issue a blue warning for heavy snow and a yellow warning for freezing at 06:00 on February 6. At the peak of returning home travel before the Spring Festival, in the past few days, many departments have focused on key areas and key links, and made every effort to do a good job in monitoring, forecasting and early warning services.
According to the ** Meteorological Observatory, the southern region continued to rain and snow freezing weather, from February 6 to 7, southeast Chongqing, northeast Guizhou, southeast Hubei, southern Anhui, central and northern Hunan, northern Jiangxi, northwest Zhejiang and other places have heavy to heavy snowfall, local heavy snowfall, the cumulative snowfall in some of the above areas is 5 to 18 mm, locally more than 20 mm, the new snow depth is 3 to 10 cm, and the local snow is more than 18 cm. 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.
In the face of rain, snow and freezing weather, the Ministry of Emergency Management launched and adjusted the emergency response in a timely manner, sent a working group to the local area to assist and guide, prepared for the allocation of disaster relief materials, and deployed 130 rescue teams for ice and snow removal projects in key areasMore than 10,000 people and more than 4,000 sets of equipment, 10 rescue teams of 500 people and some aircraft and snow melting agents for cross-provincial ice and snow removal projects, and make every effort to prepare for emergency rescue.
The China Meteorological Administration has taken the initiative to meet the needs of 10 high-impact industry departments such as transportation, energy, and electric power, and strengthened the joint consultation, early warning and dispatch mechanism, and meteorological departments at all levels have issued a total of 4,215 early warning messages and delivered 1.38 million person-times.
In Hubei, according to meteorological information, the Provincial Emergency Management Department coordinated and dealt with the D630 train power outage, the traffic jam incident at the Hunan-Hubei boundary of the Erguang Expressway, **dispatching**, Shennongjia Forest Area, Xiangyang, Enshi and other places, will be 250,000 quilts, cotton coats and other materials were distributed to the affected people in a timely manner.
The intensity of this round of rain and snow weather is the highest in Hunan in the past five years. From 8 o'clock on January 31 to 14 o'clock on February 4, the Hunan Provincial Meteorological Bureau sent 210 important warning information to the emergency responsible persons of the province, cities and counties, covering 32920,000 person-times. As of the 4th, the Hunan electric power department has carried out a total of 21 ice melting (times) of transmission and distribution lines. Traffic control is implemented at the entrances of more than 50 expressways and more than 400 toll stations in the province. The general aviation department stopped all low-altitude flight activities on February 1, and the airport carried out de-icing and snow operations in a timely manner.
In addition, the meteorological departments of Shandong, Hebei, Shaanxi and other places organized consultations, research and judgment in a timely manner, and carried out rolling monitoring, forecasting and early warning for key regions, key industries and key units, and strengthened the emergency response linkage of meteorological disaster risks.
Industry experts said that this round of rain and snow freezing cooling range is large, long-lasting, "wind, rain and snow" a variety of weather superposition, should increase risk investigation, with the help of science and technology, the implementation of various measures to deal with rain, snow and freezing weather, to protect the safe and stable operation of the project.
Recently, the Henan and Hebei sections of the middle route of the South-to-North Water Diversion Project have experienced the most extensive heavy snowfall. On February 1, the snowfall of the middle line of the South-to-North Water Diversion Project reached 5 centimeters. Early in the morning, Wang Sujuan, a 44-year-old inspector of the Central Line Yellow Management Office, counted the equipment and checked the safety of the project and the protection of the fence along the line. "Recently, we have checked all the fences along the project, and through the real-time supervision APP system for the inspection and maintenance of the middle line project on the mobile phone, we have taken photos and uploaded them after finding problems, so that the inspection is planned, the process is supervised, the analysis is carried out afterwards, and the processing can be traced, and the informatization of management has been realized. ”
Up to now, 104 ice cables, 132 sets of medium heat pipe ice melting equipment, 48 sets of hot cable ice melting equipment, 105 sets of jet ice disturbing equipment, and 6 sets of bubble ice disturbing equipment have been laid along the middle route of the South-to-North Water Diversion Project, 4 emergency rescue support teams have been invested, 3 ice period garrison points have been set up, and 43 inspection teams have been inspected and inspected daily along the project.
Industry experts believe that it is necessary to continue to strengthen windproof, cold-proof and anti-freezing measures, implement the objectives, tasks and measures of water transportation during the glacial period, improve the emergency plan for freezing disasters, ensure that the emergency rescue force maintains a hot start state at all times, and ensure the safe and stable operation of the project. Strengthen overall planning and scheduling, ensure the water demand along the South-to-North Water Diversion Project, fully meet the water supply demand of the water-receiving areas and the water demand for external water transfer, and make a good water source reserve for the arrival of the peak water consumption period after the Spring Festival.
