Intermittency and Coherent Structures Near the Air-sea Interface in the Planetary Boundary Layers
Abstract
LONG-TERM GOAL. Our primary, long-term objective is to understand turbulence in the planetary boundary layers (PBLs) on the basis of its calculation through large-eddy simulation (LES) techniques. There are many aspects to achieving this understanding: exploring the variety of large and meso-scale environments that occur in nature; achieving sufficiently large Reynolds number (Re) so that the intermittent inertial behavior is qualitatively similar to that in nature; determining the space-time distributions of and controlling circumstances for the cascade, dissipation, and air-sea fluxes; determining the character and dynamical roles of coherent structures in the PBL; examining the interactions of surface gravity waves and PBL turbulence; discovering the degree to which significant coupling occurs between the oceanic and atmospheric PBLs; and developing better PBL and air-sea flux parameterizations.
