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

  • The DPRA Heat stress report uses only two possible values for the Bowen ratio: 0.4 and 3.0.
  • By default, functions such as trees and vegetation generally have a ratio of 0.4. Other functions have a ratio of 3.0.
