Multiple departments strengthen monitoring and early warning, build a solid line of defense, and write a "warm answer sheet" for rain, snow, and freezing weather

　　From January 31 to February 5, the strongest winter rain, snow and freezing weather since 2009 affected central and eastern my country. The Central Meteorological Observatory will continue to issue blue snow warning and freezing yellow warning at 06:00 on February 6. At the peak of travel back home before the Spring Festival, many departments have focused on key areas and key links in the past few days and made every effort to provide monitoring, forecasting and early warning services.

　　According to the Central Meteorological Observatory, rain, snow and freezing weather continued in the south. From February 6th to 7th, parts of southeastern Chongqing, northeastern Guizhou, southeastern Hubei, southern Anhui, central and northern Hunan, northern Jiangxi, and northwest Zhejiang There are heavy snowfalls in the area, and heavy snowstorms in local areas. The cumulative snowfall in some of the above-mentioned areas is 5 to 18 millimeters, and locally more than 20 millimeters. The new snow depth is 3 to 10 centimeters, and locally more than 18 centimeters. There is freezing rain in parts of central and eastern Guizhou, most of Hunan, mountainous areas in northwestern Jiangxi, mountainous areas in southern Anhui, and mountainous areas in western Zhejiang.

　　In the face of rain, snow and freezing weather, the Emergency Management Department promptly activated and adjusted the emergency response, sent working groups to local areas to assist and provide guidance, made preparations for allocating central disaster relief materials, and deployed 130 ice and snow removal project rescue teams in key areas with more than 11,000 people and more than 4,000 units. A set of equipment, cross-provincial ice and snow removal project rescue teams of 10 teams with 500 people, some aircraft, and snow melting agents are fully prepared for emergency rescue.

　　The China Meteorological Administration took the initiative to meet the needs of 10 high-impact industry departments such as transportation, energy, and electricity, and strengthened joint consultation, early warning, and dispatching mechanisms. In this process, meteorological departments at all levels have issued a total of 4,215 early warning messages and delivered them to 1.38 million people.

　　In Hubei, based on meteorological information, the Provincial Emergency Management Department coordinated and handled the power outage of the D630 train and the traffic jam on the Hunan-Hubei border on the Erguang Expressway. Video dispatch was carried out in Shiyan, Shennongjia Forestry Area, Xiangyang, Enshi and other places to transfer 25,000 quilts, Materials such as cotton coats 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 8:00 on January 31 to 14:00 on February 4, the Hunan Provincial Meteorological Bureau sent 210 issues of important warning information at the provincial, municipal, and county levels to emergency responders across the province, covering 329,200 people. As of the 4th, the Hunan Electric Power Department had carried out ice melting on 21 transmission and distribution lines. Traffic control is implemented at the entrances of more than 400 toll stations on more than 50 highways in the province. The general aviation department stopped all low-altitude flight activities on February 1, and the airport promptly carried out ice and snow removal operations.

　　In addition, meteorological departments in Shandong, Hebei, Shaanxi and other places organized timely consultations and judgments to carry out rolling monitoring, forecasting and early warning for key areas, key industries and key units, and strengthened emergency linkage on meteorological disaster risks.

　　Industry experts said that this round of rain, snow, and freezing weather has a large cooling range, a long duration, and a variety of "wind, rain, and snow" weather superpositions. Risk investigation efforts should be stepped up, and with the help of science and technology, various measures to deal with rain, snow, and freezing weather should be implemented to protect the people. The project operates safely and smoothly.

　　Recently, heavy snowfall weather with the widest impact has occurred in the Henan and Hebei sections of the South-to-North Water Diversion Center Line. On February 1, the snowfall on the middle line of the South-to-North Water Diversion Project crossing the Yellow River reached 5 centimeters. Early in the morning, 44-year-old Wang Sujuan, an inspector of the Yellow Crossing Management Office along the middle line, took stock of the equipment and checked the safety of the project and the protection of the fence along the line. "Recently, we have inspected all the fences along the project line, and used the real-time supervision APP system for inspection and maintenance of the middle line project on the mobile phone. After discovering problems, we took photos and uploaded them, so that the inspections are planned, the process is supervised, there is analysis afterwards, and the processing can be tracked , realizing the informatization of management.”

　　Up to now, 104 ice-blocking cables, 132 sets of medium-heat pipe ice-melting equipment, 48 sets of thermal cable ice-melting equipment, 105 sets of jet ice-scrambling equipment, 6 sets of bubble ice-scrambling equipment have been deployed along the middle route of the South-to-North Water Diversion Project, and 4 emergency rescue equipment have been deployed. To support the team, 3 Ice Age garrison points were set up, and 43 inspection teams conducted daily inspections along the project route.

　　Experts in the industry believe that wind, cold, and antifreeze measures should be continuously strengthened, the goals and tasks of water transportation during the Ice Age should be implemented, and the measures and requirements should be improved. Emergency plans for freezing disasters should be improved to ensure that emergency rescue forces maintain a hot-start state at all times and ensure the safe and smooth operation of the project. Strengthen overall planning and dispatch to ensure water demand along the South-to-North Water Diversion route, fully meet the water supply needs of water-receiving areas and external water transfers, and prepare water reserves for the peak water consumption period after the Spring Festival.
