Common Realistic Stable Boundary Layers

Analyses of observations in the atmospheric boundary layer have emphasized stationary homogeneous conditions in order to facilitate understanding and construction of similarity theory. Most actual boundary layers are heterogeneous or nonstationary, or both, particularly for stable conditions. It is argued that simple similarity theory cannot be modified for many of these conditions. In fact, the concept of a boundary layer and simple views of heterogeneity must be reconsidered. Some aspects of nonstationarity and heterogeneity are illustrated in terms of FLOSSII and CASES99 data and some approaches for future work are offered.
