Is there any way to prevent the sky from raining? Scientific methods, etc.

Scientific methods can artificially influence the weather to prevent the sky from raining. Here are some methods:

1. Artificial rain elimination. Artificial rain elimination is to use large-scale and large-scale artificial rainfall enhancement operations in the upstream areas of precipitation clouds to accelerate the diffusion of the energy of the weather system, and at the same time, make airborne water droplets form quickly in advance and land on the ground in advance. This method can make some precipitation fall early, thus ensuring the scheduled good weather.

2. The conditions for the formation of precipitation are sufficient water vapor and an appropriate number of condensation nuclei in the clouds. Therefore, the method of artificial rainfall is to introduce artificial condensation nuclei into the clouds. Generally, the catalyst is sent into the cloud by means of airplanes, rockets, anti-aircraft guns, balloons, and burning silver iodide on the ground in the updraft area. Planes generally fly to an altitude of about 6,000 meters to pierce the clouds and spread catalysts. Rockets and anti-aircraft guns directly bombard appropriate parts of thunderclouds, and the warheads are loaded with silver iodide and sent into the clouds. A silver iodide flame bomb is hung under the balloon, which rises into the clouds and burns above the freezing level, releasing the catalyst. For warm clouds with a temperature above zero, hygroscopic substances such as salt powder, urea, calcium chloride, etc. are generally used to turn the water vapor in the cloud into large water droplets and fall into rain. For cold clouds with temperatures below zero, artificial crystal nuclei such as silver iodide are sown, or dry ice, liquid nitrogen, etc. are sown to increase the number of ice crystals in the cold clouds and improve precipitation efficiency.

It should be noted that these methods all achieve the purpose of preventing rain from the sky by affecting the weather. During the implementation process, scientific principles and relevant laws and regulations need to be strictly adhered to.
