Similarity of convective boundary layer structures of atmosphere and lake: numerical experiments with eddy-resolving models
The possibility of the simultaneous development of turbulent penetrative convection in the atmosphere and the lake during the night-time cooling of a near-surface water layer is shown. The numerical investigation of the hydrodynamics equations has been made on the basis of large-eddy simulation approach. The results of calculations of convective processes in both natural media obtained by usage of observed data are presented. The identity of the spatial structure and the energy transformations in the boundary layers of the atmosphere and the lake is shown.
