geocat.comp.meteorology.relhum_water(temperature, mixing_ratio, pressure)#

Calculates relative humidity with respect to water, given temperature, mixing ratio, and pressure.

Definition of mixing ratio if, es - is the saturation mixing ratio ep - is the ratio of the molecular weights of water vapor to dry air p - is the atmospheric pressure rh - is the relative humidity (given as a percent)

rh = 100* q / ( (ep*es)/(p-es) )

Parameters

temperature (numpy.ndarray, list, or float) – Temperature in Kelvin
mixing_ratio (numpy.ndarray, list, or float) – Mixing ratio in kg/kg. Must have the same dimensions as temperature
pressure (numpy.ndarray, list, or float) – Pressure in Pa. Must have the same dimensions as temperature

Returns

relative_humidity (numpy.ndarray) – Relative humidity. Will have the same dimensions as temperature
