OA13. Turbulence in the atmospheric boundary layer - basic studies:

Event Information

Main goal of this symposium is to characterize turbulence and the mixing and stiring properties of boundary layer regimes in atmosphere. The problem of scale dependent parametrization of turbulence and mixing processes for flow dynamics at respective larger scales in a hierarchy of models (large-eddy simulations of boundary layer flows with subgrid turbulence parametrization, regional models with subgrid boundary-layer flow parametrization, and global climate and weather prediction models) will be of utmost importance. Especially, the mixing height parametrization over flate homogeneous/heterogeneous and over complex terrains on one hand and the theoretical and field experiment methods in use for mixing heihgt determination and evaluation on the other hand should be discussed. The role of organized vortices and other coherent motions in the PBL and their proper parametrization are further major topics.
