my country launches trial operation of new generation weather radar multi-observation mode service

According to news from this site on May 3, according to the China Meteorological Administration, on May 1, my country launched the trial operation of the new generation weather radar multi-observation mode business. The China Meteorological Administration will promote the establishment of a forecast-led multi-observation mode operation mechanism for typical weather such as strong convection, precipitation, and clear skies, enhance the support capabilities of weather radar in monitoring, forecasting and early warning services for severe convective weather, and build a solid foundation for meteorological disaster prevention and reduction. A line of defense.

According to reports, radar is an "important tool" for disastrous weather monitoring in major countries, and a "sharp tool" for "pulsing" extreme weather and short-term forecast services. The China Meteorological Administration launched the pilot operation of radar multi-observation mode in 2021. After 3 years of pilot work, especially since 2023, after strengthening the interaction between observation and forecast, the operation of radar observation mode led by forecast has been explored. mechanism to better utilize the observation benefits of the new generation of weather radar.

This year, the nationwide business trial operation will make the operation mode of the new generation weather radar better Match weather processes to provide more accurate radar observation data for forecasts and warnings. This site learned from the announcement that

during the trial operation, forecasters can independently control the observation mode of radar operation and choose three categories

including fixed mode, intelligent prompt mode and adaptive mode.

According to the deployment, the radar observation mode switching settings are determined by the meteorological bureaus of each province (autonomous region, municipality directly under the Central Government) based on local actual conditions, and are also responsible for organizing business trial runs. Among them, it is necessary to keep good value adjustment and switching software operation records, collect typical cases of severe convective weather, and conduct business benefit evaluation. National business units such as the Meteorological Detection Center of the China Meteorological Administration, the National Meteorological Center, and the Earth System Numerical Prediction Center will be responsible for radar business, data transmission, short-term forecast and warning, and data assimilation and application respectively.

The China Meteorological Administration stated that at present, Jiangnan, South China and other places in my country have entered a period of frequent severe convection.

This work will further promote the application of radar observation data and effectively build a solid foundation for meteorological disaster prevention The first line of defense for disaster reduction

. In addition, my country’s first low-inclination orbit precipitation measurement satellite, Fengyun-3G, was also officially put into operation on May 1. The Fengyun-3G satellite was successfully launched on April 16, 2023. It is mainly used for precipitation climatology research and precipitation monitoring of disastrous weather systems. It can provide information on the three-dimensional structure of precipitation in mid-latitude regions around the world. Its successful launch makes my country the only country in the world that simultaneously operates four low-Earth orbit civilian meteorological satellites: morning and evening, morning, afternoon and tilt.

The above is the detailed content of my country launches trial operation of new generation weather radar multi-observation mode service. For more information, please follow other related articles on the PHP Chinese website!
