- geocat.comp.meteorology._relhum_water(t, w, p)#
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
t (
numpy.ndarray
,list
,float
) – Temperature in Kelvinw (
numpy.ndarray
,list
,float
) – Mixing ratio in kg/kg. Must have the same dimensions as temperaturep (
numpy.ndarray
,list
,float
) – Pressure in Pa. Must have the same dimensions as temperature
- Returns
rh (
numpy.ndarray
) – Relative humidity. Will have the same dimensions as temperature
