Session ID#: 56677

Session Description:
Turbulent exchange of momentum, heat, gases, and particles at the land-atmosphere-ocean interfaces provide essential forcing for atmospheric and oceanic dynamics, surface energy and water budget, carbon and nitrogen cycles, pollutant dispersion, wind-pollination, and spread of plant diseases. The dynamic structure of turbulent boundary layers governs vertical mixing, which plays essential roles in long distance transport, cloud formation, chemical reactions, and phytoplankton growth. Improving the knowledge of boundary layer processes and turbulence is indispensable for predicting and understanding weather, climate, environment, and ecological systems. This session will present contemporary themes in turbulent boundary layer studies based on theoretical, experimental, and numerical viewpoints. Topics of interest include: dry and moist ABL dynamics, turbulent exchange processes over heterogeneous landscapes including urban and plant canopies, flow over mountainous terrain, marine atmospheric boundary layer, dispersion and diffusion in turbulent boundary layers, evapotranspiration, the role of turbulence in biogeochemical cycles, and surface-boundary layer system feedbacks.
