The benefits of rain cannot be overstated. In the scorching heat, a downpour of rain turned the tide of relief. What if artificial rainfall can be done. This is exactly what American scientist Vincent Schaefer first thought. He used frozen carbon dioxide (dry ice ) to form clouds by condensing water vapor in the air . He was able to make cotton-like clouds by throwing dry ice near the Berkshire hills. That is why he is called the father of artificial clouds. In the heat of the sun, the water of various ponds , rivers and seas turns into water vapor. Because the water vapor is light, it rises to the top and forms clouds with the help of air dust particles , sand particles, etc. In this way, when the shape of the cloud gets bigger and heavier , it rains. Performing this natural process in a human controlled manner is called artificial rainfall. In artificial precipitation , sometimes the whole process , sometimes partially (converting water vapor into clouds) is controlled. In order to control the whole process, the water of a body of water is first evaporated with a large fan. The light vapor rises to the surface and mixes with the air dust. However, this coagulation can also be controlled artificially by throwing silver iodide particles. In this case , silver iodide particles are dispersed from the ground using guns or rockets , or from the sky to the ground, using air or air to collect natural or artificially created water vapor. In hot regions , calcium chloride is used for this purpose . This process of artificial rain is quite expensive. Artificial rain has brought a message of hope to different countries of the world . China is the biggest beneficiary. Rainfall in general is very low in the northern part of China. The condition of other water sources is also very bad. Therefore, by using artificial rain, they have been able to increase the water level of rivers by up to 13%.
