Webevaporation of water vapor. Although about 90% of the evaporated water falls back into the sea (see Air– Sea Interaction: Freshwater Flux), the remainder represents about one-third of the precipitation which falls over land. The geographical variation of the atmospheric heating drives the weather systems and theirassociatedwinds ... WebMar 26, 2024 · Based on Fick's law of diffusion, this provides a driving force for diffusion of water away from the surface. We call this diffusive flux of water vapor evaporation. It is driven by the difference between the equilibrium vapor pressure of water at the surface and the partial pressure of water vapor in the bulk of the room air.
