Abstract The interannual heat content variability in the tropical south Indian Ocean (SIO) and its relationship with El Niño–Southern Oscillation (ENSO) is studied. The baroclinic ocean response to stochastic wind stress predicted by a simple analytical model is compared with two integrations of the ECHO-G coupled general circulation model. In one integration, ocean–atmosphere interactions are suppressed in the tropical Pacific Ocean, so that this integration does not simulate ENSO. In the other integration, interactions are allowed everywhere and ENSO is simulated. The results show that basinwide variability in the SIO heat content can be produced by two mechanisms: 1) oscillatory forcing by ENSO-related wind stress and 2) temporally stochastic and spatially coherent wind stress forcing. Previous studies have shown that transmission of energy from the tropical Pacific to the southern Indian Ocean occurs through coastal Kelvin waves along the western coast of Australia. The results in this paper confirm the occurrence of such transmission. In the ECHO-G simulations, this transmission occurs both at the annual time scale and at interannual time scales. Generation of offshore Rossby waves by these coastal Kelvin waves at interannual time scales—and, in particular, at the ENSO time scale—was found.

Coastal Kelvin Waves

<p>The impact of intra-seasonal coastally trapped waves on SST in the Canary upwelling system is studied in satellite estimates of sea surface height, wind, and temperature, using a composite analysis of propagating upwelling and downwelling events. We focus on Spring, the season of strongest SST variability at this frequency. The results obtained show that the average wave reaches an amplitude at sea level of +/- 2 cm and is associated with an SST signal of +/-0.4 °C in the vicinity of the upwelling front, located off Senegal. Strikingly, this composite wave is reinforced by a constructive meridional wind anomaly when it reaches the upwelling front, the wind signal is likely as important as the wave in terms of SST impacts. We discuss the possible cause of this synchronicity in terms of basin-scale atmosphere and ocean waves.<br>Keywords:<br>- Impact<br>- Coastal Kelvin waves<br>- Intra-seasonal<br>- Boundary upwelling systems<br>- Composite analysis of spring<br>- Tropical Atlantic</p>

Abstract Process-oriented hydrodynamic modeling is employed to study the interaction of along-slope flows with an idealized submarine shelfbreak canyon. The model is forced via prescription of oscillatory flows superposed on steady background flows of various strength and direction. Findings suggest that purely oscillatory flow does not produce significant net onshore transport of dense water. It is rather the steady component of the flow that creates substantial up-canyon flows of ∼0.05 Sv (1 Sv = 106 m3 s−1) in volume transport. This takes place exclusively for flows running on average against the propagation direction of coastal Kelvin waves, whereas flows of the opposite direction operate to suppress cross-shelf density fluxes.
