With the water, there is transpiration, which is the water that flows through the plant, evaporation, which is water that goes from the ground to the air directly, and then when the water goes into the water table. With drip irrigation, you get less loss to the water table and to evaporation, but it doesn't impact transpiration. For water that winds up the air, no idea there. I'd guess that irrigation would have no impact to down wind precipitation in a given area.
