The theory is tested with a coarse-resolution ocean general circulation model configured in an idealized geometry. A series of experiments performed to examine the sensitivity of the deep stratification and the overturning circulation to variations in wind stress and diapycnal.
The ocean’s large-scale meridional overturning circulation is an important element of the earth’s climate system. Our understanding of basic aspects of this circulation, such as the processes and quantities that determine its intrinsic adjustment time scales, remains extremely limited.

Samelson College of Oceanic and Atmospheric Sciences, Oregon State University, Corvallis, OR, USA Abstract. A three-dimensional analytical model of meridional overturning in a basin with a southern-hemisphere circumpolar connection is presented. The overturning circulation can be understood as a “pump and valve” system, in.

Based on an advanced graduate level course, the book represents fundamental insights into the structure of the physical theory of the large-scale dynamics of the oceans. The author has maintained throughout a blend of analytical and numerical results so as to achieve as deep a physical understanding of the dynamics of the large-scale circulations as possible. Oceanic currents are largely driven by the surface wind stress; hence the large-scale atmospheric circulation is important to understanding the ocean circulation. The Hadley circulation leads to Easterly winds in the tropics and Westerlies in mid-latitudes. Mesoscale turbulence in the ocean strongly affects the circulation, water mass formation, and transport of tracers. Little is known, however, about how mixing varies on climate timescales. We present the first time-resolved global dataset of lateral mesoscale eddy diffusivities at the ocean surface, obtained by applying the suppressed mixing length theory to satellite-observed velocities.

Numerical modeling of coastal ocean circulation underwent a sea change during the CoOP years. In the late 1980s and early 1990s, when CoOP was conceived and implemented, most of the focus in modeling subinertial coastal circulation was on the linear, first-order wave equations of coastal trapped wave theory.

The Kuroshio, like its Atlantic counterpart the Gulf Stream, is a surface current that moves huge volumes of warm water from.

Some recent laboratory and numerical studies of idealized ocean gyres and circumpolar currents are reviewed in the context of what they might tell us about the relative role of eddy transfer and mixing in setting the structure of the large-scale ocean circulation. 1.

The overall project goals are to assess how oceanic mesoscale, sub-mesoscale, and. Thermohaline circulation THC is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. The adjective thermohaline derives from thermo-referring to temperature and -haline referring to salt content, factors which together determine the density of sea water. Wind-driven surface currents such as the Gulf Stream. Ocean currents are measured in sverdrup sv, where 1 sv is equivalent to a volume flow rate of 1,000,000 m 3 35,000,000 cu ft per second. Surface currents are found on the surface of an ocean, and are driven by large scale wind currents. They are directly affected by the wind—the Coriolis effect plays a role in their behaviours. A thermistor chain was towed 1400 km through the eastern North Pacific subtropical frontal zone in January 1980. The observations resolve surface layer temperature features with horizontal wavelengths of 0.2–200 km and vertical scales of 10–70 m.
