Abstract

The turbulent kinetic energy (TKE) produced by buildings in an urban central business district (CBD) was studied. Measurements from 45 sonic anemometers placed within the CBD were used and the anemometer data was divided into three groups. Comparisons of the spectra between the three groups were made for three release periods in IOP-4, 1600-1700 UTC, 1800-1900 UTC and 2000-2100 UTC. It was observed that the upwind areas had about 70% larger TKE values with more of energy from low frequency eddies, primarily those with periods of greater than 30 seconds. It was also observed that the open areas had more energy in eddies with periods of greater than 30 seconds than the street canyons.
