In order to improve the safety of weather modification operation, a system is established to generate warning products and recommended products for artificial precipitation enhancement with the radar echo extrapolation products of TREC, TITAN technology, and safe shooting area data. The system can make warning products by means of the relationship between 30 min and 60 min extrapolation radar products and maximum shooting distances of cannons and rockets, calculate the shooting angles by means of the relationship between current radar products and locations of weather modification operation, and make real time and objective recommended products through screening by means of the safe shot area technology, so to achieve safe and efficient operation and to avoid making mistakes.
