ANALYSIS OF WIND DATA FROM A SOUTH CAROLINA COASTAL FOREST

Abstract

The report summarizes the mean wind and turbulence characteristics in and above a jungle-like South Carolina coastal forest. The vegetation was black gum-red maple. Data on leaf area density estimates as well as stem densities are tabulated. The mean vector wind had two notable features: a nearly constant speed in the lowest two-thirds of the canopy, and a turning of wind direction with height in the same layer. All three components of the turbulence intensity were larger below the canopy, especially the longitudinal component. Variance spectra of the vector wind speed indicated that an inertial subrange existed at all heights above and below the canopy, and that as far as could be determined the energy dissipation rate was nearly constant with height.
