Abstract:

Longitudinal and transverse horizontal wind velocity variability of parameterized based on data collected for the Bureau of Land Management BLM between 1980 and 1982. The BLM data sets were used to derive horizontal wind velocity components and standard deviations of these components in the longitudinal downwind u, sigma u and transverse crosswind v, sigma v directions for various time averages. The standard deviations were plotted versus wind speed so that trends in the change of values could be determined. A methodology was used to develop a theoretical algorithm to account for turbulence production mechanisms due to shear, buoyancy and mesoscale processes. Empirical fits were determined for both the u and v wind directions over four different time averages. The results were related to puff growth in the x, y directions and form the basis for improving a puff dispersion model for near- coast overwater regions.
