Analysis of radar echo characteristics on the weather system of fitting aircraft artificial precipitation enhancement

Weather system favorable to precipitation enhancement operating,precipitation enhancement operation cloud and their radar echo characteristics were analyzed by the Doppler radar data and routine weather data in Huishan mountain of Shenyang from 2004 to 2005.The operating conditions,occasions,regions and so on for aircraft precipitation enhancement operations were discussed,in order to provide the scientific basis for aircraft artificial precipitation enhancement operations.
