Abstract: A method for modifying the weather by channeling dry air masses over large bodies of water by means of an artificial barrier built at an acute angle as to the incoming dry air mass that comprises a low air resistance belt to channel air movement and a high resistance belt to deflect incoming dry air into the low air resistance belt that terminates at a large body of water. Once over a large body of water the dry air mass will readily collect moisture released by the large body of water by evaporation and then be taken by prevailing trade winds over land where the moisture will be deposited in the form of rain.
