Abstract

This work investigates the impact of terrain heterogeneity and stability conditions (stable and unstable) on the local turbulence kinetic energy (TKE) around an industrial site using 36 months of data collected at the experimental site SIRTA (Instrumental Site of Atmospheric Research by Remote Sensin). These measurements show that the normalized TKE (TKE/U2: where U is the wind speed) is highly depended on the upstream complexity of the terrain (presence of forested areas or buildings) whatever the stability conditions (stable, unstable). The highest values of normalized TKE are obtained for unstable thermal stratification for all wind direction sector in the zones located behind the forested areas.
