Developments related to weather radars are discussed, taking into account the diagnostic method and short-term hazardous weather forecasts with update information, the need for specialized weather radars, the installation of the first specialized weather radars in the USSR at airports approximately 20 years ago, the initiation of the production of new generation radars in 1975, data processing with statistic correlations between radio-echo intensity and hazardous phenomena, and the utilization of the multilevel display method for estimating highly intensive radio-echo areas. The sources of meteorological information for ATC systems are considered, giving attention to weather information presented on the controller's display.
