| Zusammenfassung |
| 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 < RiB ≤ 2.5. The maximum (average)
relative errors for the turbulent transfer coefficients for momentum and
sensible heat are 12% (1%) and 9% (1%), respectively. |
