Updated geostrophic circulation and volume transport from satellite data in the Southern Ocean
Frontiers in Earth Science, 2023 Introduction: A geodetic estimation of the surface geostrophic currents can be obtained from satellite data by combining sea surface height measurements obtained from altimetry missions with geoid data from gravity missions.

Satellite Altimetry and Current-Meter Velocities in the Malvinas Current at 41°S: Comparisons and Modes of Variations [PDF]
, 2017 Three year long current-meter arrays were deployed in the Malvinas Current at 418S below a satellite altimeter track at about 10 years intervals. Surface geostrophic velocities (SGV) derived from satel- lite altimetric data are compared with the in situ ...

Bottom-trapped currents as statistical equilibrium states above topographic anomalies [PDF]
, 2012 Oceanic geostrophic turbulence is mostly forced at the surface, yet strong bottom-trapped flows are commonly observed along topographic anomalies. Here we consider the case of a freely evolving, initially surface-intensified velocity field above a ...

The dynamical balance, transport and circulation of the Antarctic Circumpolar Current [PDF]
, 2004 The physical ingredients of the ACC circulation are reviewed. A picture of thecirculation is sketched by means of recent observations of the WOCE decade.

, 2014 We investigate the non-linear equilibration of a two-layer quasi-geostrophic flow in a channel forced by an imposed unstable zonal mean flow, paying particular attention to the role of bottom friction.

Analysis of Model Results for the Turning of the Wind and Related Momentum Fluxes in the Stable Boundary Layer [PDF]
, 2009 The turning of wind with height and the related cross-isobaric (ageostrophic) flow in the thermally stable stratified boundary layer is analysed from a variety of model results acquired in the first Global Energy and Water Cycle Experiment (GEWEX ...

Coriolis force in Geophysics: an elementary introduction and examples [PDF]
, 2000 We show how Geophysics may illustrate and thus improve classical Mechanics lectures concerning the study of Coriolis force effects. We are then interested in atmospheric as well as oceanic phenomena we are familiar with, and are for that reason of ...

Southern South China Sea boundary current transition from summer to winter
Frontiers in Marine Science, 2023 The characteristics and mechanism of the southern South China Sea (SCS) Western Boundary Current (WBC) summer-winter transition have been investigated. The transition typically starts in early October and lasts for about two weeks. Above the thermoclines

Singularities in Fully Developed Turbulence [PDF]
, 2014 Phenomenological arguments are used to explore finite-time singularity development in different physical fully-developed turbulence (FDT) situations. The role played by the cascade physics underlying this process is investigated.

The flow of the Antarctic circumpolar current over the North Scotia Ridge [PDF]
, 2009 The transports associated with the Subantarctic Front (SAF) and the Polar Front (PF) account for the majority of the volume transport of the Antarctic Circumpolar Current (ACC).
