人工降雨的工作原理
The working principle of artificial rainfall
簡單來說，人工降雨就是通過人工的方式，將云層中的水氣變成雨水，然后播撒在地面上，算是一種人造氣象現(xiàn)象，那么到底怎么做才能將云層中的水分變成雨滴呢？
In short, artificial rainfall is an artificial way to turn the water into the rain in the clouds, and then spread it on the ground. It is a man-made weather phenomenon, so what can we do to make the water in the cloud a rain drop in the earth?
首先，并不是所有的云層都能形成降雨！大家需要先明白云層高度和降水的關系，那就是只有特定高度的云層才可以形成降水。
First of all, not all clouds can create rainfall. We need to first understand the relationship between cloud height and precipitation, that is, only a specific height of clouds can form precipitation.
按照氣象規(guī)律，一般來說，高高掛起的是卷積云高度在6000米以上，大片雪白云朵高度一般在2000到6000米之間，這些云層并不足以形成降水。只有那些高度在2000米以下，且含水汽較大的雨層云才有可能降雨，確定這些云層的存在和位置，然后在通過高空作業(yè)，可以選擇用飛機，也可以選擇用高炮，不過各地還是選擇高炮的方式多一些，這樣成本更低，高炮發(fā)射炮彈，在這些云層中播撒催化劑，促進形成降水。
According to the meteorological law, generally speaking, the height of the coiling cloud is above 6000 meters, and the height of large snow-white clouds is generally between 2000 and 6000 meters, and these clouds are not enough to form precipitation. Only those raining clouds with high water vapor below 2000 meters are possible to rain, determine the presence and position of these clouds, and then work at high altitude, choose to use the aircraft, and choose to use the artillery, but there are more cannon choices everywhere, so that the cost is lower, the artillery projectile is fired. In these clouds, catalysts are used to form precipitation.
