Abstract

The gradient diffusion parameterization of the Reynolds stress is modified by adding a bulk momentum transport term. Comparisons to available data indicate that this term accounts for the gusts or ‘downsweeps’ of higher momentum fluid into the canopy and ejections of lower momentum fluid out of the canopy. This term results in realistic mean wind speed profiles.
