WebThe Bowen ratio is quite small (0.2 or less) for all the saturated surfaces shown in this figure. Evaporation from dry vegetation We consider a fully vegetated surface with a single effective surface temperature and humidity (a ‘single-layer canopy’). The sensible heat flux originates at the leaf surfaces, whose temperature is T 0 WebEquilibrium Bowen ratio is near 1 at 0ºC, and decreases to about 0.2 at 30ºC. As relative humidity is decreased from 1 to smaller values, evaporative cooling increases. The equilibrium Bowen ratio is the maximum possible Bowen ratio for a wet surface.
