Pollution is continuously increasing these days in Delhi NCR. The air has become poisonous and the air quality index has crossed 450. In Delhi, all schools up to class 5 have been closed till 10th November. A ban has been imposed on construction work. To reduce the increasing pollution, cloud seeding i.e. artificial rain is done. In 2018, a plan was made to reduce pollution in Delhi through this. Let us know how helpful it is in preventing pollution and how artificial rain is made.
Due to pollution, there is smog in Delhi NCR. People have stopped taking morning walks. To avoid pollution, people have started wearing masks. According to doctors, due to increasing pollution, people are also facing watery eyes and respiratory problems.
How are artificial clouds formed?
In this process, silver iodide is sprayed in the sky with the help of aircraft. As soon as it comes in contact with the air and clouds present in the sky, clouds start forming rapidly and these clouds cause rain. This is also called cloud seeding. Silver iodide is like snow and it increases the amount of water in humid clouds and then it rains. This is done to deal with the severe situation of extreme drought areas and pollution. Cloud seeding is also used to deal with severe fire accidents.
This was planned earlier also
In 2018, a plan was made to create artificial rain in Delhi to reduce pollution. The professors of IIT Kanpur had made complete preparations for cloud seeding, but due to the weather not being favourable, artificial rain was not made.
Cloud seeding is not easy in cold weather
According to scientists, it is easier to do cloud seeding i.e. artificial rain before and after monsoon because at that time there is more moisture in the clouds. In cold weather, there is very little moisture in the clouds and cloud seeding is not easy.
How effective is this process?
Artificial rain is used in drought prone areas. With this, crops that are getting damaged due to lack of rain can be saved. At the same time, the water level of rivers can also be equalised. This process is also effective in reducing the increasing pollution.
