Does artificial rainfall need approval?

Does artificial precipitation enhancement need approval? The implementation of artificial precipitation enhancement must go through strict preparation, declaration and operation procedures and meet certain weather conditions. In order to ensure aviation safety, every precipitation enhancement operation must be approved by the airspace management department and can only be carried out within the prescribed time limit. Therefore, artificial precipitation enhancement is not arbitrary, but can be arbitrary.

Article 12 of the Regulations of People's Republic of China (PRC) Municipality on the Management of Weather Modification must be carried out in strict accordance with the operational norms and procedures stipulated by the state within the approved airspace and operation period. The competent meteorological department of the State Council, accepting at or above the county level. Accept the command, management and supervision of the local meteorological authorities to ensure the safety of operation.

There is no exact explanation for how much rain artificial rainfall can rain at a time. Sometimes it rains for a long time, sometimes it rains for a short time, depending on the number of raindrops in the clouds. The specific costs include equipment use fees and rocket fees (ranging from 2,000 yuan to 4,000 yuan per rocket). If you need to operate the plane, it will be counted separately, and there will be other miscellaneous expenses. According to the increased cost of artificial rainfall before, it is generally necessary to launch 4-8 rockets, which cost tens of thousands of yuan. If all other expenses are included, it is close to 65438+ 10,000 yuan each time. If aircraft operation is needed, the cost will be high, and hundreds of thousands are not enough. If it is only rocket operation, the cost is not high.

What kind of shells are fired by artificial rainfall? Artificial rainfall is launched by shells filled with artificial rainfall materials such as dry ice. Artificial rain bomb, referred to as rain bomb, is fired by anti-aircraft guns.

The projectile exploded into the cloud, and the catalyst was diffused into the cloud by the shock wave generated by explosion and detonation, which made the catalyst produce a large number of artificial ice nuclei, and transformed the mechanism of hail cloud and rain cloud through the action of the catalyst, thus achieving the purpose of increasing rainfall and preventing hail. It belongs to dangerous explosives.
