Moisture in the atmosphere

Moisture in the atmosphere. Moisture in the atmosphere. Saturation: When the air contains as much moisture as it can hold The higher the temperature, the more moisture air can hold. Water vapor enters the atmosphere by evaporation, sublimation to a gas, and transpiration.

MOLLIER DIAGRAM

MOLLIER DIAGRAM. Dew Point - Tdp The Dew Point is the temperature at which water vapor starts to condense out of the air, the temperature at which air becomes completely saturated. Above this temperature the moisture will stay in the air.
