Bowen ratio of 10
WebThe ratio of sensible to latent heat fluxes at the surface is called the Bowen ratio6: B = FHs/FEs. Due to the nonlinearity inherent in the Clausius-Clapeyron equation, the Bowen ratio over... WebThe Bowen ratio is the ratio between sensible heat and latent heat, which is equal to heat loss or heat gain. This ratio is used to calculate the type of heat transfer for a moist surface. Heat transfer occurs as sensible heat or latent heat.

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.
