Webwork of Bowen (Jacobs 1942,1943; Bowen 1926a,b). Since that time, oceanographers and meteorologists have adhered to Bowen's formulation with only slight modification. Sverdrup (1943) termed the "Bowen ratio" R. Over the oceans, the ratio varies from about 0.1 in low latitudes to 0.45 at 70°N and 0.23 at 70°S (Perry and Walker 1977, p. 83). WebThe conventional Bowen ratio surface energy balance method (BR method) is a relatively simple technique that in-tegrates net available energy with the ratio of the sensible and latent heat ﬂux.

The Bowen ratio is used to describe the type of heat transfer for a surface that has moisture. Heat transfer can either occur as sensible heat (differences in temperature without evapotranspiration) or latent heat (the energy required during a change of state, without a change in temperature). The Bowen ratio is generally used to calculate heat lost (or gained) in a substance; it is the ratio of energy fluxes from one state to another by sensible heat and latent heating respectively.
