Interpreting Fixed-Location Observations of Turbulence Advected by Waves: Insights from Spectral Models
Publisher: American Meteorological Society
Abstract: ssigning a physical interpretation to turbulent fluctuations beneath waves is complex because eddies are advected by unsteady wave orbital motion. Here, the kinematic effects of wave orbital motion on turbulent fluctuations ...
Breaking Surface Wave Effects on River Plume Dynamics during Upwelling-Favorable Winds
Publisher: American Meteorological Society
Abstract: his study examines the dynamics of a buoyant river plume in upwelling-favorable winds, concentrating on the time after separation from the coast. A set of idealized numerical simulations is used to examine the effects of ...
The Role of Whitecapping in Thickening the Ocean Surface Boundary Layer
Publisher: American Meteorological Society
Abstract: he effects of wind-driven whitecapping on the evolution of the ocean surface boundary layer are examined using an idealized one-dimensional Reynolds-averaged Navier?Stokes numerical model. Whitecapping is parameterized as ...
Calculating Reynolds Stresses from ADCP Measurements in the Presence of Surface Gravity Waves Using the Cospectra-Fit Method
Publisher: American Meteorological Society
Abstract: Recently, the velocity observations of acoustic Doppler current profilers (ADCPs) have been successfully used to estimate turbulent Reynolds stresses in estuaries and tidal channels. However, the presence of surface gravity ...
Observations of Turbulence in the Ocean Surface Boundary Layer: Energetics and Transport
Publisher: American Meteorological Society
Abstract: Observations of turbulent kinetic energy (TKE) dynamics in the ocean surface boundary layer are presented here and compared with results from previous observational, numerical, and analytic studies. As in previous studies, ...
Measurements of Momentum and Heat Transfer across the Air–Sea Interface
Publisher: American Meteorological Society
Abstract: This study makes direct measurements of turbulent fluxes in the mixed layer in order to close heat and momentum budgets across the air?sea interface and to assess the ability of rigid-boundary turbulence models to predict ...
