Rain Rain gone away . who can say

Rain Rain gone away . who can say when it come ?  Clouds of rain come almost every day. But refuse to shed rain !

 Cold bundles of cloud are seen repelled as if in Magic ! My friend told me that . the Fog repellents established  in connection with the Air Port repels the rainy clouds if the clouds are weak.How can I believe it ?  I am seeking Scientific  Material information about this . My friend says that in the Airport and surroundings fogs as well as clouds are repelled  I think any of the Meteorologists or climate experts may give me an explanation If my query seems a laughing stock please excuse!
