β¦ Synopsis
The concepts of mountain-induced wave drag are applied to the smaller scale problem of the boundary layer over complex terrain. It is found that the Reynolds stress and surface drag caused by surface-generated waves can be at least as large as those conventionally associated with turbulence. Conditions in which wave effects are important are identified.

## Abstract Most schemes to parametrize gravityβwave drag effectively assume that the total waveβstress is associated with a single waveβvector pointing in the direction of the stress vector. However, the wave stress over real terrain is an integral over all azimuthal directions of waveβvector cont
Gravity waves associated with stably stratified layers were observed in the planetary boundary layer at two locations in France. Using an array of three monostatic Doppler acoustic sounders, the wave speeds and directions were found. A quantitative study of the waves has been performed to determine
