How can we calculate the Bowen ratio - ResearchGate

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. WebBowen's ratio The ratio of sensible heat to latent heat transport from the ground to the atmosphere, which is generally calculated from the ratio of the vertical gradients of … WebNegative Bowen Ratio Values may occur in the evening if one or another of the fluxes reverses direction which will occur if a surface temperature inversion occurs. i.e. sensible heat directed toward the surface; while evaporation is continuing or in the less likely event of dew fall occurring while the surface is still losing sensible heat itool atr500
