Abstract

The authors performed a field measurement on the turbulent characteristics of an urban canopy layer over a cubical array using numerous fine thermocouples and nine ultra sonic anemometers. The time and spatially fluctuations of air temperature were discussed comparing the instantaneous velocity under the unstable condition. The result clearly showed that the passage of the microffont of temperature above the canopy, which are correlate the sweep and ejection motions due to a turbulent organized structure (TPS) developed within an inertial sublayer, in contrast, the temperature fluctuation below the canopy height is less sensitive to the TOB.
