An Analysis of Wind Fluctuation Statistics Collected under Stable Atmospheric Conditions at Three Sites in Alberta, Canada

Abstract

Wind fluctuation data collected under stable atmospheric conditions at two prairie sites and a site located near the Rocky Mountain foothills have been analyzed. Results of the analysis show a marked tendency for horizontal fluctuation angles to vary inversely with wind speed. In contrast, vertical fluctuation angles tended to be invariant with wind speed. Atmospheric turbulence was much greater at the foothills site than at the prairie sites. This was mainly due to the fact that standard donations of vertical wind angles were almost twice as great. Standard deviations of horizontal fluctuation angles were only about 20% greater.
