Mean Circulation and Structures of Tilted Ocean Deep Convection
Publisher: American Meteorological Society
Abstract: Convection in a homogeneous ocean is investigated by numerically integrating the three-dimensional Boussinesq equations in a tilted, rotating frame (?f?F plane) subject to a negative buoyancy flux (cooling) at the surface. ...
Horizontal Ocean Circulation Forced by Deep-Water Formation. Part II: A Quasi-geostrophic Simulation
Publisher: American Meteorological Society
Abstract: This numerical experiment aims to investigate the dynamical effects of the vertical convection of waters, occurring in regions where the cooling of the upper ocean is due to periodical, local, rough winter atmospheric ...
On the Catalytic Role of High Baroclinic Modes in Eddy-driven Large-Scale Circulations
Publisher: American Meteorological Society
Abstract: This paper investigates the tridimensional consistency of the resolution of eddy scales in simulating large-scale flows. The generation of classical wind-forced, eddy-driven double-gyre circulation is investigated with a ...
Horizontal Ocean Circulation Forced by Deep-Water Formation. Part I: An Analytical Study
Publisher: American Meteorological Society
Abstract: The horizontal ocean circulation generated by vertical convection is investigated analytically. The stratification is parameterized by a two-layer ocean and attention is focused on the spinup phase when the phenomena can ...
Structure and Causes of the Pulsation Mode in the Antarctic Circumpolar Current South of Australia
Publisher: American Meteorological Society
Abstract: The subsurface variability of potential temperature and salinity south of Australia along 130°E is studied over a 25-yr period (1980?2004). The study is done with fields provided by a global eddy-permitting model of the ...
Standing and Transient Eddies in the Response of the Southern Ocean Meridional Overturning to the Southern Annular Mode
Publisher: American Meteorological Society
Abstract: o refine the understanding of how the Southern Ocean responds to recent intensification of the southern annular mode (SAM), a regional ocean model at two eddy-permitting resolutions was forced with two synthetic interannual ...
