摘要：

Currently used and newly proposed calculation techniques for the height of the stable boundary layer (SBL), including the bulk-Richardson-number method, diagnostic equations for the equilibrium SBL height, and a relaxation-type prognostic equation, are discussed from the point of view of their physical basis and relevance to experimental data. Among diagnostic equations, the best fit to data exhibits an advanced Ekman-layer height model derived recently with due regard to the role of the free-flow stability. Its extension to non-steady regimes provides a prognostic equation recommended for use in practical applications.
