An index of the degree of water surplus over water need at any given station; it is calculated as humidity index = 100s/n, where s (the water surplus) is the sum of the monthly differences between precipitation and potential evapotranspiration for those months when the normal precipitation exceeds the latter, and where n (the water need) is the sum of monthly potential evapotranspiration for those months of surplus.

OBS

The humidity index has two uses in Thornthwaite's classification: (a) as a component of the moisture index; (b) as a basis for detailed classification of dry climates.

OBS

The term "humidity index" is not to be confused with "humidex" or "comfort index".
