Artificial precipitation, also known as artificial rain, is a scientific process in which the atmosphere is made favorable for rain by artificially changing the physical state of clouds. According to available information, this process is called cloud seeding and it is completed in three major stages.
Let us tell you that in the first step, with the help of chemicals, the air mass is sent upwards over the desired area, so that the process of cloud formation starts. In this stage, compounds like calcium chloride, calcium carbide, calcium oxide, salt and urea and ammonium nitrate are used. These compounds activate the condensation process by absorbing water vapor from the air.
clouds in the second phaseBurdenTo further increase it, things like salt, urea, ammonium nitrate, dry ice and calcium chloride are used. Due to this the clouds become heavy and dense.
In the third and final stage, when clouds are already present or man-made, cooling chemicals such as silver iodide and dry ice are sprayed. Due to this, the density of the clouds increases and they become heavy by changing into icy form, due to which they fall in the form of rain. Airplanes, rockets or balloons are used for this spraying.
It is noteworthy that the main objective of artificial rainfall is to provide adequate water to the crops, deal with the problem of drought and temporarily reduce the level of air pollution. Cloud seeding collects the moisture present in the clouds in the form of snow or droplets and when they become heavy, they fall on the ground and form rain.
According to current information, this technology is being used in many countries of the world, especially in areas where natural rainfall is unbalanced or deficient. Scientists believe that with proper scientific control and use of right chemicals, artificial rainfall can help in increasing agricultural production and maintaining environmental balance.
