The present invention discloses a method for preventing serious weather disasters, and in step 1 of the method, a conventional meteorological technique is used to find an area where thick and dense cloud layers are aggregated. Set the highest density, maximum thickness, or highest temperature rainfall position in the cloud layer, and in step 3, set one or more long rainfall zones at the rainfall position, perform artificial rainfall, Reduced cloud temperature to cause rain to fall, reduce cloud layer temperature, density and size, and release hot air below the cloud layer, allowing the cooled clouds to flow into the surrounding hot clouds Then, by lowering the temperature of these clouds and making it rain, the natural conditions that cause the meteorological disaster are lost.
