The key point of ground burner rain enhancement is the updrafts around the operation site. The layout conditions and operating conditions are analyzed with automatic meteorological station data from Bawangling of Changjiang, Yulongshan of Dongfang, Fuguang of Ledong, and Maoyang of Wuzhishan in Hainnan Province， as well as the Doppler radar data of Haikou, and the terrain characteristics of operation sites, and the catalyst diffusion is simulated using the Gaussian model. Results show that the four ground burners are on the highaltitude windward slope, where updrafts can take catalysts into clouds. By means of the comprehensive utilization of NCEP/NCAR reanalysis data, MICAPS data, and radar data to determine the operation time and to carry out the warm cloud seeding, the effectiveness of precipitation enhancement is obvious.
