An improved non-iterative surface layer flux scheme for atmospheric stable stratification conditions

Abstract

Parameterization of turbulent fluxes under stably stratified conditions has always been a challenge.Current surface fluxes calculation schemes either need iterations or suffer low accuracy. In this paper, a non-iterative scheme is proposed to approach the classic iterative computation results using multiple regressions. It can be applied to the full range of roughness status 10 ≤ z/z0 ≤ 105 and-0.5 ≤ log(z0/z0h) ≤ 30 under stable conditions 0
