- 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

) – Mixing ratio in kg/kg. Must have the same dimensions as temperaturepressure (
numpy.ndarray
,list
, orfloat
) – Pressure in Pa. Must have the same dimensions as temperature
- Returns
relative_humidity – Relative humidity. Will have the same dimensions as temperature
- Return type
