Abstract. Using temperature-salinity profiles obtained from a cruise in summer 2000, the structure and formation of the barrier layer (BL) in the South China Sea (SCS) are investigated. Fresh water flux, ocean circulation, and wind stirring are important for BL formation, depending on regions. In the eastern SCS, Philippine mountains induce heavy rainfall, resulting in a fresh water cap at the ...

West Palm Beach (Florida), ISSN 0749-0208. Hydrodynamics, sediment suspension, and morphological response on an estuarine intertidal sand flat in Tokyo Bay, Japan, are examined through a field experiment performed for 16 days in winter 20...

Abstract. We are interested here in describing the linear response of the ocean to some wind forcing, which admits fast time oscillations and may be resonant with the Coriolis force. In addition to the usual Ekman layer, we exhibit another much larger boundary layer, and some global vertical profile. That means in particular that the wind effect is no longer localized in the vicinity of the sur...

Effects of wind and waves on the surface dynamics Mediterranean Sea are assessed using a modified Ekman model including Stokes-Coriolis force in momentum equation. Using 25 years observations, we documented intermittent but recurrent episodes during which Stokes currents substantially modulate total mesoscale by two nonexclusive mechanisms: (a) providing vigorous input (e.g., where regional win...

Measurements from Whitehorse upper-air and nearby mountaintop stations were analyzed with a focus on wind energy development in the region. Fifty years of measurements indicate the region has become warmer and windier. Measurements at the upper-air station have shown increases of 2.7 ̊C for surface temperature and 1 m s for mid-valley winds over the past 50 years (1956 – 2005). The winters have ...

We construct a lattice Boltzmann model of a single-layer, ‘‘reduced gravity’’ ocean in a square basin, with shallow water or planetary geostrophic dynamics, and boundary conditions of no slip or no stress.When the volume of the moving upper layer is sufficientlysmall, the motionless lower layer outcrops over a broad area of the northern wind gyre, and the pattern of separated and isolated weste...

Using an ocean–atmosphere coupled general circulation model, air–sea interaction processes associated with the Atlantic meridional mode are investigated from a new viewpoint of its link with the Guinea Dome in the northern tropical Atlantic. The subsurface thermal oceanic dome develops off Dakar from late spring to late fall owing to wind-induced Ekman upwelling. Its seasonal evolution is due t...

The behaviour of the steady, horizontally homogeneous, neutral, barotropic planetary boundary layer (PBL) has recently been examined by Garratt and Hess. In Garratt and Hess (2002) modelled profiles of the mean wind, the geostrophic departure and turbulent stress components were compared with observations; in Hess and Garratt (2002 a,b) predicted integral measures, such as the geostrophic drag ...

Abstract A novel multi‐satellite product is used to shed light on the sea surface height seasonal cycle and associated geostrophic circulation in subpolar Southern Ocean. We find three main modes of variability governing Sea Level Anomaly cycle, all them primarily governed by wind forcing. The mode with seasonality gyres large‐scale stress curl, qualitatively consistent Sverdrup dynamics. secon...
