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. 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. Sensible heat: This is the difference in temperature without evaporation or change in temperature with ...
