Since the range of applications of boundary‐layer meteorology is broad, and my space limited, I thought it best to direct this review toward structural and dynamical fundamentals of the planetary boundary layer (PBL) rather than toward particular applications. In doing so, I have made slight reference to the particular needs of users in large‐scale circulation, air‐pollution meteorology, agricultural meteorology, and environmental engineering. Certainly, however, much PBL research owes its justification and support to those communities. This review is organized, therefore, along lines that would be generally appropriate for a discussion of any turbulent flow. Section 2 deals with the structure of the PBL, and the effects of stratification; Section 3 covers the interactions of the PBL with the surface below and the flow above; and Section 4 covers advances in measurement and (as they bear on observations) modeling.
