ABSTRACT
The wind plays an essential role in the evaporation process because, by mixing the ambient air, it replaces the saturated air next to an evaporating surface with a drier
layer of air1. Essentially, the air next to an evaporating surface becomes saturated relatively quickly, and as a result stops the evaporation process. A glass of water in a closed container protected from all air movement will not evaporate for long, even in extremely dry conditions. The wind, due to its speed and also its turbulence and vertical structure, plays a leading role in the evaporation process. For one thing, air turbulence allows the humid (saturated) air to rise while the dry air falls and becomes charged with moisture.
