WebApr 1, 1983 · The behavior of the Priestley-Taylor parameter is investigated using a simplified atmospheric boundary-layer model coupled to the Penman-Monteith equation. … WebSep 1, 1991 · The Priestley-Taylor equation, a simplification of the Penman equation, was used to allow calculations of evapotranspiration under conditions where soil water supply limits evapotranspiration. The Priestley-Taylor coefficient, α, was calculated to incorporate an exponential decrease in evapotranspiration as soil water content decreases.

On the Assessment of Surface Heat Flux and Evaporation Using
WebAbstract In an introductory review it is reemphasized that the large-scale parameterization of the surface fluxes of sensible and latent heat is properly expressed in terms of energetic considerations over land while formulas of the bulk aerodynamic type are most suitahle over the sea. A general framework is suggested. Data from a number of saturated land sites … Webpaper these mechanisms are examined through the Priestley- Taylor equation [Priestley and Taylor, 1972], which stipulates that the ratio a between potential evaporation and equilibrium evaporation (i.e., the radiative term of Penman's formula) is constant and equal to 1.26 on average.
