Abstract: Significant progresses in the radar meteorology and meteorology radar have been made by the scientists and technicians in Chinese Academy of Meteorological Sciences in the past half century. The early history and recent development of radar research work in Chinese Academy of Meteorological Sciences are reviewed. The main topics are as following: The technology and applications of analogy weather radar, digital weather radar, Doppler radar, dual linear polarization radar, bistatic radar; the application of these radars on watching, warning and nowcasting of hail, heavy rain fall, typhoon; recent research work on field experiment for heavy rain fall and typhoon, the 3-D mesoscale wind structures of heavy rainfall, squall line by dual Doppler radar and bistatic radar network technique; the microphysical structures retrieval by dual linear polarization radar, 3-D mosaic and nowcasting with CINRAD. The radar research work in recent years in the National Laboratory of Severe Weather are focused on Doppler Lidar, millimeter radar, movable and airbone radar technologies and their applications. The dropsounding system is also developed and used in heavy rainfall and typhoon systems observation and forecast.
