The most straightforward method preserves the Bowen ratio, i.e., adjusts both the sensible and the latent heat fluxes by the same percentage, based on the 30-min energy balance residual (Twine et al. 2000). At first, this kind of partitioning was chosen in the absence of a better ...

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.
WebSep 21, 2002 · The Bowen ratio was obtained based on thermodynamic considerations with the following result: Bo E = a ( Ts − Ta) b, where a varies from 0.077 to 0.078, b varies from 0.67 to 0.71, the correlation … WebJun 20, 2016 · Evapotranspiration in forests has been researched for a long time because it serves an important role in water resource issues and biomass production. By applying the reciprocal analysis based on the Bowen ratio concept to the canopy surface, the sum result of sensible and latent heat fluxes, i.e., actual evapotranspiration (ET), is estimated …
