Thornthwaite Monthly Water Balance Model
The Thornthwaite water balance (Thornthwaite, 1948; Mather, 1978; 1979) uses an accounting procedure to analyze the allocation of water among various components of the hydrologic system. Inputs to the model are monthly temperature and precipitation. Outputs include monthly potential and actual evapotranspiration, soil moisture storage, snow storage, surplus, and runoff.
