The effect of changes in surface resistance on temperature and humidity fields and fluxes of sensible and latent heat

In this paper we consider temperature ( Theta ) and specific humidity (Q) fields in the lower part of the planetary boundary layer and present a method for calculating the way these variables and their fluxes vary over changes in available surface moisture expressed as a surface resistance. Near the surface, the turbulence is close to equilibrium and an eddy diffusivity model enables the changes in Theta , Q, sensible heat flux (F sub(H) ), and latent heat flux (F sub(E) ) to be determined in terms of the assumed mean wind, turbulence profiles and upwind profiles of temperature and humidity. An important advantage of this method is that it is possible to consider arbitrary changes in surface properties.
