Abstract Currents effects on waves have led to many developments in numerical wave modeling over the past two decades, from choices parameterizations. The performance of models conditions with strong currents is reviewed here, and observed opposed modulations heights by tidal several typical situations are interpreted. For current variations small scales, rapid steepening enhances breaking. Using different parameterizations a dissipation rate proportional some measure steepness fourth power,...
Abstract. Coastal water dynamics along the Vietnamese middle southern coast (VMSC) region, part of South China Sea, are highly complex with large spatiotemporal variability whose drivers not yet well understood. For first time, high-resolution surface current data from high-frequency radar (HFR) measurements were obtained in this region during early (transition) phase Asian summer monsoon. The used for comparison simulation results a circulation model, SYMPHONIE, and ultimately to optimize...
In an attempt to reconciliate air-sea momentum flux estimates derived from open sea observations, large eddy simulation output fields, and wind-wave tank measurements, a series of dedicated experiments were conducted in the Large Air-Sea Facility Marseille, France. The turbulent friction velocity, upon which depends, was estimated wind measurements by applying four classical methods including eddy-covariance method inertial-dissipation method. collected data used investigate some...
Sea breeze (SB) phenomena may strongly influence air quality and lead to important effects on human health. In order study the impact of SB dynamics properties toxicity aerosols, an atmospheric mobile unit was deployed during a field campaign performed in urbanized industrialized coastal area Northern France. This combines aerosol samplers, two scanning lidars (Doppler elastic) air-liquid interface (ALI, Vitrocell®) vitro cell exposure device. Our highlights that after passage front, top...
Abstract. Transport and dispersion processes in the ocean are crucial, as they determine lifetime fate of biological chemical quantities drifting with currents. Due to complexity coastal environment, numerical circulation models have difficulties accurately simulate highly turbulent flows processes, especially energetic tidal basins such eastern English Channel. A method improving results modeling tracer Dover Strait is proposed. Surface current velocities derived from Lagrangian drifter...
The Alderney Race is assumed to have the largest tidal-stream energy potential in north-western European coastal seas. Interaction of powerful tidal stream with strong wind, high waves and irregular bathymetry creates hydrodynamic conditions extreme complexity, levels turbulence. A comprehensive dataset has been created improve understanding physical processes, turbulence, resource variability at site. database contains a large amount oceanographic meteorological measurements acquired...
Abstract. Wind and wave effects on tidal current structure turbulence throughout the water column are examined using an upward-looking acoustic Doppler profiler (ADCP). The instrument has been deployed seafloor of 18-m mean depth, off north-eastern French coast in eastern English Channel, over 12 cycles, covered period transition from spring to neap tide, forcing regimes varied calm moderate storm conditions. During storms, we observed gusty winds with magnitudes reaching 15 m s−1 heights up...
The Alderney Race, located northwest of the Cotentin Peninsula (France), is a site with high tidal-stream energy potential. Circulation through Race complex, current speed exceeding 3 m s-1 at neap tide. Towed acoustic Doppler profiler (ADCP) measurements and static point velocity were performed in July 2018 focusing on assessment circulation vertical structure tidal currents. Transect surveys revealed peculiar features local dynamics such as change location jet ebb flood flow. spatial...
