Getting through the ＂Last Mile＂ of Meteorological Early Warning —— Summary of the Pilot Project of Targeted Release of Early Warning Information
At the end of 2020, the China Meteorological Bureau and the State Administration of Radio and Television jointly issued a pilot work plan, and selected four provinces (autonomous regions) of Inner Mongolia, Anhui, Sichuan and Guizhou to carry out pilot projects to jointly promote the application of meteorological early warning information in the emergency broadcasting system. At the beginning of 2021, the China Meteorological Bureau and the Ministry of Industry and Information Technology jointly issued the "Pilot Work Plan for Accurate Targeted Release of Meteorological Disaster Early Warning SMS", which clearly carried out pilot projects for accurate targeting of meteorological disaster early warning SMS in Fujian, Guizhou and Wenchuan County, Sichuan Province.
In the past two years, various localities have continuously deepened the exploration of targeted release mechanisms and innovative technologies for emergency broadcast of meteorological early warning and meteorological disaster early warning short messages, and targeted release of meteorological early warning information has achieved phased results.
Look at the pilot project of meteorological early warning broadcast by emergency broadcast-
Gradually become a "sound" force for disaster prevention.
In Basha Village, Bingmei Town, congjiang county City, Guizhou Province, the house is built on the mountain. When encountering heavy rainfall, villagers are always in danger of landslides and landslides.
On June 29, 2022, when the rainstorm hit, it was the loudspeaker at the entrance of the village that played the disaster avoidance warning over and over again, thus avoiding a disaster.
"Fortunately, there is a big horn to wake up and evacuate to a safe place, otherwise the consequences will be unimaginable!" Villager Wang Shuisheng said.
Just one hour after the evacuation, landslides and landslides occurred in Wangjiazhai and Xinzhai of Basha Village. Thirty minutes ago, 1,196 people from 265 households were successfully transferred, achieving "zero" casualties.
The "big horn" in the mouth of the villagers is the emergency broadcast. In Guizhou, emergency broadcasting is widely distributed. By the end of 2022, there were 290,000 emergency broadcasts in Guizhou province, covering 14,000 administrative villages.
"In the past, it was time-consuming and laborious to notify things in the village by going door-to-door or making phone calls one by one, especially when receiving emergency weather warning information, which was costly in time." Sinan County, Guizhou ProvincecloseDashi, Yuexi TowncellarXu Xuekun, director of the village Committee, said, "Although the emergency broadcasting method is’ earth’, the effect is very good."
By mid-December, 2022, Guizhou Province had carried out 6,566 emergency broadcasts, covering more than 24.52 million person-times, an increase of nearly 4 million person-times compared with 2021. In some ethnic minority villages, emergency broadcasts are also broadcast in the form of "Putonghua+minority languages or dialects", which has solved the problems of illiteracy and incomprehension of some rural elderly people.

Scenes like this are being rolled out all over the country with the promotion of the construction of the "village-to-village sound" emergency broadcasting project.
On July 23, 2022, in Horqin Right Wing Zhongqi, one of the first pilot counties in Inner Mongolia Autonomous Region, Li Auntie who went out quickly called her wife after seeing the red rainstorm warning on her mobile phone. But at this time, my wife’s phone can’t get through. "I’m anxious! Seeing that it is going to rain heavily, my wife is still alone in the field, and more than 80 chickens raised at home have to rush to the high-lying shelter in the yard. "
Aunt Li, who was anxious for a long time, finally waited until her wife came back. It turned out that he forgot to bring his mobile phone. When he was working in the field, he heard the weather warning from the "village ringing" and rushed home at once. On the same day, there was a heavy rainstorm in Horqin Right Wing Zhongqi, but due to the timely warning, all departments responded effectively, causing no casualties.
In 2022, the meteorological department of Inner Mongolia strengthened the construction of early warning release capacity and expanded the pilot areas from 12 to 50. Inner Mongolia Meteorological Early Warning Information Publishing Center added 4,886 people in charge of the actual terminals of loudspeakers in villages to the WeChat enterprise number of meteorological early warning, and opened the automatic receiving function to further facilitate the broadcast of meteorological early warning.

In Anhui, at present, 16 municipal emergency broadcasting platforms have been connected, covering 1345 townships (communities), with a total of 164,800 emergency broadcasting terminals, covering 60 million people. At the same time, Anhui Meteorological Bureau has built a new mode of ordering township early warning release in the whole province-all localities can formulate localized early warning release strategies according to the characteristics of local disastrous weather, freely allocate broadcast time periods, and realize accurate broadcast of early warning information in administrative villages according to the influence range of early warning signals. In addition, on the basis of early warning signals extended to towns and communities, emergency broadcasting construction is matched to towns and communities simultaneously.
In Sichuan, the broadcasting rules of emergency broadcasting system after receiving meteorological early warning information were established, and the targeted publishing strategy and service target group were established to realize "precise circle" publishing. At the same time, based on the grass-roots meteorological disaster early warning service platform in Sichuan Province, an emergency broadcast early warning information docking and adaptation module is developed, so that the meteorological early warning information produced and released by meteorological departments at all levels in Sichuan Province can be automatically pushed to the emergency broadcast system in Sichuan Province, and at the same time, the feedback of early warning reception status and broadcast status can be obtained.
Exploring the pilot project of accurate targeted release of meteorological disaster early warning SMS-
An increasingly established "outpost" for disaster prevention and mitigation
SMS has always been one of the mainstream communication channels of meteorological early warning. With the emergence of new forms and technologies of information dissemination, people put forward new requirements for the dissemination of meteorological short messages-accuracy and intelligence.
Fujian Meteorological Bureau has established a digital demonstration system for early warning targeted release application, and independently developed and built a multi-disaster full-chain accurate targeted information release application, down to the township (street) level. In addition, based on a number of localized early warning models in which the meteorological risk early warning threshold of geological disasters in the province is automatically split, the Provincial Meteorological Bureau also automatically connected the "meteorological risk early warning+monitoring and early warning" to the hidden danger points of geological disasters in the province, and quickly provided grid-based accurate early warning short messages for 146,000 geological disaster prevention and monitoring personnel.
This practical achievement was applied and tested in the process of persistent heavy precipitation which is rare in history from May 24th to June 21st, 2022. The natural resources department of Fujian Province issued 1,523 meteorological risks and monitoring and early warning of geological disasters using the provincial early warning information release system, and the monitoring and early warning information of geological disasters was accurately delivered to the group monitoring and prevention personnel point to point, benefiting more than 55,000 people, successfully warning 53 places and avoiding 604 casualties in 135 households.
Accurate targeted publishing platform: realize the release of meteorological disaster early warning information to designated areas.
The Outline of Meteorological High-quality Development (2022-2035) proposes to promote the application of technologies such as the fifth generation mobile communication (5G) in the release of early warning information. Since then, the exploration has been deepened in many places, and the results have been equally remarkable-
Hubei Mobile, together with the Provincial Meteorological Bureau, pushed the cold wave warning 5G message to users before the arrival of the cold wave, and pushed the location and estimated time of the cold wave to the mobile phone terminal in the form of video, graphic and so on, successfully reaching 1.03 million users. Users can quickly understand the message content by simply opening the SMS. In addition, the sender can also judge the reading state of the audience according to the background data and take more accurate measures.
The meteorological department of Zhejiang Province has carried out 5G weather message service in all cities (counties) in the province, that is, on the basis of retaining the original short message products, around the two main lines of customized information push and intelligent human-computer interaction, to create a new user-centered weather message dissemination ecology, and the whole network can be pushed without the help of WeChat, Weibo and other carriers.
Chongqing has set up an exclusive local weather query application platform-"Chongqing Weather" chat robot. Based on the original ecological short message window of 5G message terminal, the presentation of weather short messages is more media-oriented, and users can be reached actively.
Jiangxi Meteorological Service Center and the mobile company upgraded the traditional short message service of weather forecast in an all-round way, set up a 5G mobile information publishing system for weather forecast, and realized on-demand push service according to different user needs, weather conditions, geographical location of users, early warning signals, etc. (Yang Chunzhu, Su Jingwen, Gao Fei, Sui Jianli, Wang Zhenhan, Wang Bing, Li Jiao, Wang Yue, Zheng Hao, Yang Long, Xie Jian and Edward Zhang contributed to this paper).
