By the end of 2022, China had a total of 120 upper-air meteorological observation stations, as well as more than 100 wind profile radars and more than 900 GNSS/MET observation instruments. At present, China has built the world's largest and most influential weather radar monitoring network, with basically localized radar hardware and software facilities. The reform of radar weather operation has been pushed forward, and the Radar Meteorological Centre has been established and brought into operation. China's first S-band dual-polarization phased-array weather radar has been successfully developed and put into test operation. The new generation of weather radars fully realized "instant scanning and transmission".
CMA continued to optimize the new generation weather radar operating software (ROSE) with independent intellectual property rights, and developed four types of automatic warning products for severe convective weather: hail, tornadoes, thunderstorms and gales, and short-lived heavy precipitation. The weather radar mosaic product was upgraded and put into service, achieving national and provincial applications and reducing the product update frequency to six minutes. The high temporal and spatial resolution of weather radar data plays an important role in the development of real-time, kilometer-scale products.
