What are the 24 new generation weather radars in East China?

East China Doppler weather radar is about to bid farewell to "individual combat". According to the news from the Shanghai Regional New Generation Doppler Weather Radar Networking Jigsaw and Application Coordination Meeting held on February 30th, 65438, 24 new generation weather radars built in East China will complete the networking jigsaw before the flood season next year to realize continuous warning of disastrous weather.

Doppler weather radar is one of the most effective tools to monitor severe weather such as typhoon and rainstorm, especially to capture small and medium-scale weather systems. However, a single radar can only see the radius of 200 kilometers, so it is difficult to continuously track and monitor the disastrous weather process. For this reason, since the 1980s, the United States, Britain, Japan and other countries have successively carried out research on radar network splicing technology, such as the Doppler weather radar network in the United States, which provides a national radar splicing with a resolution of 2 kilometers every 6 minutes.

After the completion of this project, forecasters in East China can know the distribution and evolution of precipitation system in East China in time from the radar puzzle, and accurately locate the specific location of disastrous weather in township streets with the help of geographical distribution query technology in the system, so as to integrate resources, give full play to the benefits of Shanghai's new generation weather radar network, and greatly improve the monitoring and forecasting ability of typhoon, rainstorm and strong convective weather in East China. The leaders of meteorological departments in East China who attended the meeting put forward the problem of massive storage of radar data, and it is urgent to open 2 trillion broadband networks between provinces to solve the transmission problem of data sharing. At the same time, it is agreed to take the radar puzzle project as the starting point, especially to further strengthen regional cooperation at the technical level, and give full play to the role of regional center by taking information sharing, joint declaration of scientific research projects, development and utilization of numerical forecast, weather early warning in big cities and talent construction as the starting point.
