Large groups of water molecules are pulled by surface tension into a round ball to minimize surface area per unit volume. In gravity, tear-drop-shaped droplets are formed as water falls…Water would rather stick to itself than to many surfaces.

Trees Supply Rainfall
Trees are essential for harnessing inland moisture, utilizing it, transpiring it, and aiding in inland precipitation. Wind connects precipitation to a place, and through water cohesion, roots soak ground moisture. During the day, this moisture leaves pores of plants or stomata, adding moisture into the air, which travels downwind until water vapor binds together to form rain.
“Reafforestation…in particular outside the tropics — can increase P [precipitation] and the overall intensity of the hydrologic cycle, especially during warmer periods of the year and potentially in a warmer future climate.”
David Ellison, research consultant Swedish University of Agricultural Sciences
