Research Abstract

Spatial distribution of turbulence within a cubical canopy was observed in the outdoor reduced urban scale model experiment using multi-number of thermocouples and sonic anemometers. It revealed that the turbulence field in cubical canopy was affected by turbulent structures developed above the canopy layer, which is much larger than the size of individual cubes.
