摘要: Abstract Large-eddy simulations (LES) of wind-driven shallow water flows with Langmuir turbulence have been conducted and scalar transport surface transfer dynamics analyzed. In these flows, the largest scales consist full-depth circulation (LC), parallel downwind-elongated, counter-rotating vortices acting as a secondary structure to mean flow. is generated by interaction shear current Stokes drift velocity induced gravity waves. absence resolved waves, turbulence-generating mechanism parameterized via well-known Craik–Leibovich vortex force ( Craik Leibovich, 1976 ) appearing in momentum equation. Simulations do not resolve thus top domain taken non-deforming, free-slip, wind shear-driven surface. LES guided LC field measurements Gargett Wells (2007) shows that plays major role determining throughout entire column at affects its through (1) full-depth, large-scale (2) near-surface, small-scale eddies. Two key parameters controlling extent two mechanisms are (1)the ratio λ ˜ = / H , where dominant wavelength waves generating depth (2)the turbulent number, Lat, which inversely proportional wave forcing relative forcing. Results from varying combinations Lat analyzed order understand effect on dynamics.
