However, the artificial rain in Dubai and its surrounding cities has come from a completely new technology. Drones were used in this. In fact, the scientists of the University of Reading have been doing a great job on this for some time now. Although it is very expensive to make this rain. Artificial rain has been happening in other ways. Usually artificial clouds are made in it and then rain is made from them. This has been happening in many countries.
How is artificial rain
Making artificial rain is a scientific process. For this, artificial clouds are first made. In the oldest and most popular technique, silver iodide is added to the clouds by reaching the top via aircraft or rocket. Silver iodide is similar to natural ice. Because of this, the water in the clouds becomes heavy and it rains.
Some experts say that it is necessary to have clouds for artificial rain. Cloud seeding cannot be done without a cloud. Silver iodide is sprayed on cloud formation. Due to this the steam turns into water droplets. Heaviness comes in them and due to gravity it falls on the earth. According to a report by the World Metrological Organization, 56 countries around the world are using cloud seeding.
This is called cloud seeding
This process of artificial rain is being used for the last 50-60 years. This is called cloud seeding. Cloud seeding was first demonstrated in February 1947 in Bathurst, Australia. This was done by General Electric Lab.
In the 60s and 70s, many times artificial rain was done in America. But later it decreased. Artificial rain was originally used to avoid the problem of drought.
This is how cloud seeding happens
Such an experiment is also done to avoid the danger of rain
China has been using artificial rain. During the Beijing Olympics in 2008, China used this method through 21 missiles. So that the danger of rain can be avoided. However, recently no such news has come from China which shows that it still uses this method to deal with pollution. Experts say that China has now stopped cloud seeding to control pollution.
In the year 2018 there was preparation for artificial rain in Delhi
In the year 2018, preparations were made to get artificial rain due to increase in pollution in Delhi. Scientists of IIT Kanpur had prepared artificial rain to deal with the serious situation of air pollution. Just waiting for the weather to become favorable. The IIT professor had also acquired a plane from ISRO to get artificial rain. But due to the unfavorable weather, artificial rain could not be done.
Experiments have been done in Lucknow and Maharashtra
The technique of artificial rain has already been tested in parts of Maharashtra and Lucknow. But it has not been used in any large area to deal with pollution. Although artificial rain has been done with success in India for many decades. The Rain and Cloud Physics Research, affiliated to IIT, has contributed a lot in this regard.
Artificial rain has been used in some parts of the country
Cloud seeding was first used in India in 1951. SK Chatterjee, the first Director General of the Indian Meteorological Department, was a well-known cloud scientist. Its experiments started in India under his leadership. He then made artificial rain by sending salt and silver iodide over the clouds in balloons filled with hydrogen gas. In India, cloud seeding has been used to combat drought and raise the water level of dams.
Such rains have been made continuously in the country.
In 1951, the Tata firm made this kind of rain at many places in the Western Ghats. Then the Rain and Cloud Institute of Pune made such artificial rain in many areas of Uttar Pradesh and Maharashtra. In India such rains were made in the year 1983, 84 and in Tamil Nadu such work was done to deal with the drought in 93-94. Artificial rain was made in Karnataka in 2003-04. In the year 2008, there was a plan to have such rain in 12 districts of Andhra Pradesh. It is meant to say that India has been very ahead in the field of artificial rain.
Last year, IIT professors had told that it is easier to get artificial rain before and during the monsoon. But it is not easy in the winter season. Because during this time the amount of moisture in the clouds is not high.
