geocat.comp.meteorology.relhum_water#
- 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
, orfloat
) – Temperature in Kelvinmixing_ratio (
numpy.ndarray
,list
, orfloat
) – Mixing ratio in kg/kg. Must have the same dimensions astemperature
pressure (
numpy.ndarray
,list
, orfloat
) – Pressure in Pa. Must have the same dimensions astemperature
- Returns:
relative_humidity (
numpy.ndarray
) – Relative humidity. Will have the same dimensions astemperature
