Based on the history meteorological data in Dalian, the hailsuppression operation warning, decisionmaking and discriminant index system is established and analyzed. The hailsuppression conception model is devised. Based on the uptodate hailsuppression technology, research findings, and experiences from local practices, the technical operation scheme is designed and analyzed scientifically. On the basis of the MICAPS system and Doppler radar, the advanced technologies such as artificial hailsuppression, radar detection, satellite remote sensing, upperair meteorological detection, geographical information, lightning location, etc., are integrated. The artificial hailsuppression decisionmaking and command system, adapting to Dalian, is developed, which has such functions as hailsuppression operation warning, hail cloud identifying, operational decisionmaking, operational scheme determination, realtime effectiveness analyses, etc. It is highly automatic and practical, and easy to use and spread. The system is planned to put into hailsuppression operation use.
