Artificial rain

American scientists made the first artificial rain in 1946 by introducing a small amount of carbon dioxide into the clouds. In the near future, China will also make artificial rain to serve the 2008 Olympic Games.

Artificial rain formed by spraying a small amount of chemicals (silver iodine or carbon dioxide) into the clouds, causing condensation to become heavier and heavier and fall to the ground. One can add more desiccant compounds to increase the efficiency of this process.

The first person to make artificial rain was chemist Vincent Schaefer. In 1946, he brought a small amount of carbon dioxide into the clouds, causing a snowfall near Schenectady, a New York City suburb.

When it comes to rain, you have to talk about clouds. But even in the absence of clouds, people can still produce rain.

Millions of North Americans used to live in severe droughts because the area was very cloudy. The amount of water collected is mainly due to snow in winter. But today, chemical spraying technology has caused this snowfall to increase by 20% every year and by spring, snow melt provides enough water until the following winter.

Although some scientists have doubts about the ability to create rain in this place can reduce rain elsewhere. But there is no clear evidence yet.

China is one of the countries that are widely using artificial rain methods. Thereby many large areas of this country escape poverty. This is also a method to clean up the air that will be used to treat pollution before the 2008 Olympic Games.
