Bowen's ratio
Webwork of Bowen (Jacobs 1942,1943; Bowen 1926a,b). Since that time, oceanographers and meteorologists have adhered to Bowen's formulation with only slight modification. … WebThus, the Bowen ratio is about 10 for deserts, 2–6 for semi-arid regions, 0.4 to 0.8 for temperate forests and grasslands, 0.2 for tropical rain forests and 0.1 for tropical oceans (Nobel 1999) In well-watered crops, transpiration (see textbook Chapter 4), and hence water evaporation from the leaf, is high, so the Bowen ratio is low.

paleo baked chicken breast recipeThe 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. summer thank you imagesWebBowen'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 vapour pressure and temperature.
