Moisture
Moisture = Water Vapor (gas)
Gets into the atmosphere by:
1.Evaporation = liquid to gas (opposite of condensation)
2.Transpiration = plants release water

Factors Affecting Moisture
Amount of insolation or temp.
Amount of water vapor in air (humidity).
Surface area – spread out evaporates faster.
Wind speed – wind increases evaporation

Relative Humidity
Relative humidity = ratio of water vapor in air to amount of water vapor possible.
Dew Point = condensation temp.- always lower than air temp.- equal to 100% relative humidity.

Psychrometer
Instrument that measures humidity.
Dry-bulb = regular thermometerWet-bulb = wet thermometer
Use ESRT charts and differences in these temperatures to get DP and RH.
