Study on optimization of cloud seeding ground operation technology based on regional multi-parameters dynamic contrast method

Abstract

In order to optimize the cloud seeding ground operation technology, 26 operations were selected for the study from cloud seeding ground operations in 2015-2017, and a regional multi-parameters dynamic contrast method (K-value method for short) was proposed. The K-value method was used to evaluate the operation effects brought by different equipments, number of shells, and methods of operation. The results show that the ground operation has a good rainfall enhancement effect, the rainfall enhancement rate within 3 hours after operation is 14.4%, and the effect is the best at 2 hours. The rocket has a faster rainfall increase speed and a larger rainfall increase rate, the effect brought by rocket is better than the antiaircraft gun. When the number of shells in a single antiaircraft gun operation is N≤35, or the number of shells in a single rocket operation is 2 1 was prolonged by 1 h. The optimization technology had obvious effect.
