Turbulent exchange of momentum, heat, and mass at the land-atmosphere-ocean interface provides essential forcing for atmospheric and oceanic dynamics, surface energy and water budget, carbon 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, and chemical reactions. 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 atmospheric boundary layer (ABL) dynamics, cloud-ABL interactions, turbulent exchange processes over heterogeneous landscapes including urban environments and plant canopies, flow over mountainous terrain, marine ABL, dispersion and diffusion in ABLsI evapotranspiration, turbulence in biogeochemical cycles, extreme weather events, and feedbacks in the surface-boundary layer system.
