Boundary-Layer Meteorology Aims and scope Submit manuscript

Abstract

Air flowing over a forest canopy is examined for instabilities driven by Jeffreys' drag mechanism. The calculations indicate that the mechanism is generally effective in strong wind conditions and extremely effective when the boundary layer supports wave trapping. The instability forces the free wind down amongst the trees, creatingepisodes of stress in the foliage.
