It is raining in Shaoguan

The latest one is in Guangdong on February 9? Timely rain? It is the technology of artificial rainfall that makes it rain in many places in Guangdong Province, which has alleviated the drought for many times. From February 9 to 10, there were heavy rains to heavy rains in western Guangdong, Pearl River Delta, Shaoguan, Qingyuan and Heyuan, local heavy rains and heavy rains in other cities and counties. Because this is artificial rainfall, there will be no strong cold air and heavy precipitation in Guangdong Province during the Spring Festival holiday, and the weather is generally stable.

It is reported that the current rainfall in Guangdong has ended. The rockets used this time are about 187. This rainfall can increase rainfall, alleviate the drought in some areas of Guangdong, bring good news to farmers engaged in planting, help Guangdong to increase showers, help reservoirs to store water, reduce the risk of forest fires, bring moderate cooling and purify the air. After this rain, the visibility is really much higher and the air is much better.

However, there is a difference between artificial precipitation enhancement and artificial rainfall. Literally, it can be seen that artificial precipitation increases when it rains, generally increasing by 20% to 40%. However, if it doesn't rain under natural conditions, artificial precipitation enhancement can't be implemented. The meteorological conditions of artificial precipitation enhancement are: there should be thick cumulus clouds with rich water vapor over the places where artificial precipitation enhancement is needed, the height of cloud top should be between 6 100 meters and 12200 meters, and there should be a breeze on the ground less than 10 kilometers per hour. Artificial precipitation enhancement can use anti-aircraft guns, rockets, balloons to sow catalysts, airplanes to sow catalysts, and the ground burns smoke. Aircraft are responsible for the altitude above 5000 meters, and anti-aircraft guns and rockets are responsible for the air from 3000 meters to 5000 meters.

When it comes to artificial rainfall, it literally means rainfall by artificial means. Artificial rainfall does not need to use the natural conditions of rainfall, but it can only be carried out under specific natural conditions. Generally, aircraft and rockets are used to spread dry ice, silver iodide, salt powder and other catalysts in the cloud to make the cloud precipitation or increase precipitation, so as to alleviate or alleviate farmland drought, increase irrigation water or reservoir water supply capacity, or increase power generation.
