利用新近发展的涡粘性非局地公式，导出了稳定层结的正压Ekman边界层深的精化诊断和预报方程。在完全中性大气边界层、夜间大气边界层和海洋边界层主要受温跃层静态稳定性影响的情况下，所提出的诊断方程分别简化为Rossby-Montgomery方程、Zilitinkevich方程和Pollard-Rhines-Thompson方程。在一般情况下，它适用于一系列区域，包括受近地表浮力通量影响的长寿命大气SBL和自由大气中的静态稳定性。诊断性和预测性的SBL深度方程都根据大气测量的最新数据进行了验证。版权所有(C)2002皇家气象学会。
Refined diagnostic and prognostic equations for the depth of the stably stratified barotropic Ekman boundary later (SBL) are derived employing a recently developed non‐local formulation for the eddy viscosity. In well‐studied cases of the thoroughly neutral SBL, the nocturnal atmospheric SBL and the oceanic SBL dominantly affected by the static stability in the thermocline, the proposed diagnostic equation reduces to the Rossby–Montgomery, Zilitinkevich and Pollard–Rhines–Thompson equations, respectively. In its general form it is applicable to a range of regimes including long‐lived atmospheric SBLs affected by the near‐surface buoyancy flux and the static stability in the free atmosphere. Both diagnostic and prognostic SBL depth equations are validated against recent data from atmospheric measurements. Copyright © 2002 Royal Meteorological Society.
