It's another year of Spring Festival, on January 26, the Spring Festival begins. As the largest and largest "periodic migration" involving the largest number of people, the Spring Festival transportation is not only a comprehensive test of transportation capacity, but also a comprehensive test of meteorological monitoring and forecasting services. This year's Spring Festival is particularly special - the central and eastern regions have been hit by continuous widespread rain, snow and freezing weather. Under the rain and snow, what are the challenges faced by the national transportation and what are the new characteristics of meteorological services? China Meteorological News reporters went to many places to show you the meteorological stories on the way to the Spring Festival.
Emergency Command Center of Anshun Highway Administration of Guizhou Province: "Meteorological Navigation" ensures safety and efficiency
At 8:50 on February 1, Hu Qiuhong, the main person in charge of the Anshun Meteorological Observatory in Guizhou Province, did the first thing he did when he went to work was to open the "Anshun Highway Meteorological Intelligent Service Platform" to check the "congestion" color of the main traffic road conditions, and remind the Municipal Highway Administration to do a good job in emergency prevention of dense fog to ensure the driving safety of national and provincial highways during the Spring Festival. During the Spring Festival, Hu Qiuhong was very concerned about the impact of the weather on traffic. "We call this system 'Highway Meteorological Intelligent Service Platform', and the Highway Administration directly calls it 'Meteorological Navigation', which is quite vivid. Hu Qiuhong said. At this time, Mo Meixu, head of the emergency command center of the Municipal Highway Administration and the road network monitoring department on the outskirts of the city, and Guo Juncheng, director of the Information Service Center of the Municipal Meteorological Bureau, are reviewing the applicability of "meteorological navigation" during the snow condensation in late January this year and the details that need to be optimized. 
On February 1, the Anshun Municipal Highway Administration reviewed the monitoring and response to freezing weather in late January through "meteorological navigation" Figure Li Mengyuan.
In the emergency command center of Anshun Highway Administration, through the "meteorological navigation", it can be clearly seen that some sections of the road have visibility of less than 200 meters of fog, the road color is orange, a small part of the road section is light yellow, and the overall traffic conditions are better. Mo Meixu introduced that with "meteorological navigation", the command center can achieve a map overview, a map of the general manager, according to the real-time weather conditions and weather forecast command of road conditions. In case of major disaster weather, targeted patrols can be issued, safety reminders can be issued, and in case of critical situations, temporary traffic control measures can be taken, or "speed with the road" to guide vehicle traffic, so as to improve road traffic efficiency under the premise of ensuring safety.
At present, the "meteorological navigation" system integrates 4 national highways and 10 provincial highways in Anshun jurisdiction, with a cumulative mileage of 747The meteorological traffic information of 06 kilometers can intelligently present the impact degree and mileage of high-impact weather such as fog, freezing and heavy rain in each road section. Just like the navigation software used when driving, you can know which roads have good weather conditions, which sections of the road are prone to congestion, and which parts are particularly prone to congestion or even danger.
At this juncture when the cold air is active in the Spring Festival, the weather must not only be accurately forecasted and monitored, but also the service products must be refined. Guo Juncheng said.
During the impact of the strong cold wave on January 24 this year, a total of 7 provincial roads in Anshun City were frozen, among which part of the S313 Guangping Line was more serious, and traffic was interrupted for a time. With precautionary salt spraying and emergency de-icing, road traffic resumed after 1 hour and 15 minutes.

The new forecast product can be directly distributed to all public works sections for use, and there is no need to re-edit, which greatly improves work efficiency. Lin Yi, chief of the professional service section of the Provincial Meteorological Service Center, introduced.
On January 30, Liaoning had the first snowfall during the Spring Festival, Zhao Zhenchi had already begun to pay attention, in the exchange with Di Bowen and Wei Jinghua, he learned that the railway "takes snow as the order", and when it reaches the level of moderate snow, it is necessary to organize personnel to remove snow and make every effort to ensure the safety of train operation.
The weather service was scheduled 3 days in advance. With the assistance of Zhao Zhenchi, Wei Jinghua added the forecast products of the snowfall area to the railway line in the weather situation express report on January 28. As the snowfall approaches, the daily weather service products will be released after repeated communication between the two parties. On the evening of January 29, the morning and evening of the 30th, Zhao Zhenchi issued three additional railway meteorological service reports, focusing on reminding the lines of moderate snow and above and the snowfall period.
In the early morning of January 31, Zhao Zhenchi rushed to the unit, in fact, not only to collect feedback, but also to have an important task: to assist Di Bowen in the production of the report materials of the Ministry of Industry and Electric Power of China State Railway Group, to deploy the railway in advance to deal with high-impact weather, and to provide decision-making reference for the safe operation of Spring Festival trains. After the two met, they quickly summarized the weather on January 30 and exchanged weather trends from February 4 to 5, focusing on the high-impact weather that threatened the safe operation of the railway.
For the first snowfall weather service effect of the Spring Festival, Di Bowen gave the answer. Due to the communication and analysis of the two sides in advance, China Railway Shenyang Bureau Group arranged the deployment in advance, and a total of 1,910 cadres and employees were dispatched in the snowfall weather on January 30, and a total of 2,230 groups of turnouts were cleaned to effectively prevent the impact of snowfall and ensure the safety and smoothness of railway transportation during the Spring Festival. ”
