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)

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

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