WebThe bowen ratio over different surfaces have different values. Can we then identify the underlying surface roughness type based on the bowen ratio alone? I am thinking of the latitudinal and altitudinal dependence of the heat flux regime. For example, assume that there are the same vegetation distribution at 1km above sea level (a.s.l) and 4 km ... 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.
