Supercomputer modelling of geophysical turbulence
A.V. Glazunov (INM RAS), E.V. Mortikov (RCC MSU, INM RAS)
Numerical models of turbulent flows in atmospheric and oceanic boundary layers, based on Direct Numerical Simulation and Large Eddy Simulation methodologies, are presented. The models are developed in INM RAS and RCC MSU, they employ original methods for numerical solution of hydrodynamics equations and new approaches to "subgrid" (turbulent) closures. The models are efficiently parallelized and adopted to heterogeneous architectures of modern supercomputers. Several idealized flow simulations are discussed including stratified boundary layer flows under large Reynolds numbers and geophysical turbulent flows over heterogeneous surfaces. These simulations are necessary for validation and development of perspective parameterizations of turbulent exchange in general circulation models of ocean and atmosphere.
