Abstract
Daily mean values of the Priestley-Taylor coefficient, α¯, are derived from a simple model of the daily growth of a convective boundary layer. For a particular control set of driving environmental variables, α¯ is related to the prescribed bulk surface resistance, rS by 1/α¯ = 1/α0 + mrS for parameters α0 and m. The dependence of the parameters α0 and m on weather is explored and a potential use of this linear relation to provide information about regional values of rS is indicated.
