A54A:
Atmospheric Boundary Layer Processes and Turbulence III

Submit an Abstract to this Session



Session ID#: 33406

Session Description:
Turbulent mixing in Earth’s atmospheric boundary layer (ABL) is responsible for the surface exchange of trace gases, momentum, and energy with the atmosphere. Improved understanding of ABL dynamics, which requires characterization of ABL turbulence in response to a range of ambient conditions (forcing), is necessary for predicting and understanding processes in hydrology, ecology, meteorology, and climatology. This session will present contemporary themes in ABL research based on theoretical, experimental, and numerical viewpoints. Topics of interest include: dry and moist ABL dynamics, surface-atmosphere exchange processes over heterogeneous and complex terrain including urban environments and plant canopies, flow over mountainous terrain, the marine atmospheric boundary layer, dispersion and diffusion in the atmosphere, evapotranspiration, the role of turbulence in biogeochemical cycles, and feedbacks in the surface-boundary layer system.
