人工降雨,顾名思义就是人们根据降水形成的原理,人为地补充某些形成降水的必需条件,促使云滴加速凝结,或合并增大而形成降水现象。换句话说,就是要使天上的云彩、水气听从人们的指挥,从空中降下来造福人类。 Artificial rainfall, as the name implies, is based on the principle of precipitation formation, artificially replenishing some of the necessary conditions for precipitation, prompting rapid condensation of cloud droplets, or merge to increase the precipitation phenomenon. In other words, it is to make the clouds and sunshine in the sky obey the command of the people and come down from the sky for the benefit of mankind.
