This session is open to different approaches of the study of the turbulence in the atmosphere and in the ocean: theoretical, observations and field experiments, numerical modelling and laboratory experiments. A proper understanding and description of turbulence in the atmosphere and in the environment is very important in order to deal correctly with transport processes, relevant both as parameterization for meteorological oceanic and atmospheric models, and for air and water quality applications. The purpose of this session is to discuss and stress the importance of turbulence at different scales and their highly nonlinear processes, which are present in topics as: Observational Methods in the Atmospheric Boundary Layer, Stable Boundary Layers, Large Eddy Simulations, Boundary Layer Processes, Numerical Models, Boundary Layer Clouds and turbulence-fog interactions, evening and morning transitions of the ABL, Stratified and Rotation driven events, Coastal areas, Ocean surface flows, Convective proceses, Intermittency, Fractality, etc.
