Vertical Structure of Turbulence in the Lower Atmospheric Boundary Layer above a Deciduous Forest in Complex Terrain Agricultural and Forest Meteorology

It is well known that parameterizations developed using observations from flat terrain have difficulty over complex terrain, which motivates a better understanding of turbulence exchanges occurring in these areas. In this work we addressed the question of how the vertical variability of turbulence features evolves over the lowest few hundred meters of the convective and nocturnal boundary layer above a forested ridge as a function of cloud cover and mean wind. We used one year of observations obtained from a WindCube V2.1 lidar installed in eastern Tennessee in the Southeast U.S. coupled with observations from a 60-m micrometeorological tower. The wind lidar has 20-m range gates spanning from 40 m to 300 m above ground.
