The Bowen ratio is a property of a surface, specifically the ratio between two types of heat transfer (sensible heat and latent heat). The wetter the surface, the lower the ratio.[1]

Notes

  • DPRA Heat stress report uses only two possible values for the Bowen ratio: 0.4 and 3.0.
  • Terrains such as grassland and functions such as trees and vegetation generally have a ratio of 0.4.
  • Water is special in the sense that during the day the ratio is 0.4 and at night the ratio is 3.0.
  • The other functions and terrains have a Bowen ratio of 3.0
