Abstract

The clear day boundary layer development from low-level jet (LLJ) and gravity wave dominated flow to the fully developed boundary layer in Oklahoma City (OKC) observed using Doppler lidars were analyzed. The averaged wind profiles and standard deviation at 1347 UTC, when the LLJ and gravity wave dominate the flow were presented. It was found that the urban area has more than double the standard deviation below 100 meters. The results show that there are significant differences in the mean turbulence intensity and spatial integral length scale over urban and suburban domains.
