||Wind measurements from the Savannah River Laboratory - WJBF TV tower in Beech Island, South Carolina were used to compute turbulence parameters which were then compared with similarity theory predictions summarized by Hanna (1981). The parameters computed were sigma(sub u), sigma(sub v), sigma(sub w) and spectral scales lambda(sub m) and l(sub E). Turbulent heat flux and temperature gradient measurements were used to help compute L and w(sub *). Results of the comparison between measurement and theory are mixed. Good correlation between measurement and theory are obtained for the nondimensional parameters sigma(sub u)/w(sub *) and sigma(sub v)/w(sub *) in unstable condition. The computed Eulerian length scales also agree well with predictions for the unstable boundary layer. The results for neutral conditions also show poor agreement of nondimensionalized sigma's but reasonably good agreement of the nondimensionalized time scales with predictions.
