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) )


Relative humidity. Will have the same dimensions as temperature

Return type

rh numpy.ndarray
