Use a psychrometer or hygrometer and appropriate tables to determine the relative humidity and dew-point temperature of the air.

Atmospheric Moisture

•Explain the processes involved when water changes state

Use a psychrometer or hygrometer and appropriate tables to determine the
relative humidity and dew-point temperature of the air.

Explain the adiabatic process and its effect on cooling and warming the air.

Calculate the temperature and relative humidity changes that take place in air
as the result of adiabatic cooling.

Describe the global patterns of precipitation and its variability.
