Journal ArticleDOI
A finite-volume, incompressible Navier Stokes model for studies of the ocean on parallel computers
TL;DR: A preconditioner is used which, in the hydrostatic limit, is an exact integral of the Poisson operator and so leads to a single algorithm that seamlessly moves from nonhydrostatic to hydrostatic limits, competitive with the fastest ocean climate models in use today.
Journal ArticleDOI
Hydrostatic, quasi‐hydrostatic, and nonhydrostatic ocean modeling
TL;DR: In this paper, the Navier Stokes model on the sphere has been used to model the global circulation of the ocean, from the convective scale to the global scale, and a solution strategy has been proposed to deal with small-scale phenomena which are not in hydrostatic balance.
Journal ArticleDOI
Open-ocean convection: Observations, theory, and models
John Marshall,Friedrich Schott +1 more
TL;DR: In this article, the authors review what is known about the convective process in the open ocean, in which the properties of large volumes of water are changed by intermittent, deep-reaching convection, triggered by winter storms.
Journal ArticleDOI
North atlantic climate variability: Phenomena, impacts and mechanisms
John Marshall,Yochanan Kushnir,David S. Battisti,Ping Chang,Arnaud Czaja,Robert R. Dickson,James W. Hurrell,Michael S. McCartney,Ramalingam Saravanan,Martin Visbeck +9 more
TL;DR: Variability of the North Atlantic Oscillation and the Tropical Atlantic dominate the climate of North Atlantic sector, the underlying ocean and surrounding continents on interannual to decadal time scales as mentioned in this paper.
Journal ArticleDOI
Closure of the meridional overturning circulation through Southern Ocean upwelling
John Marshall,Kevin Speer +1 more
TL;DR: A review of recent studies emphasizes the importance of wind-driven upwelling in the Southern Ocean for global ocean circulation as discussed by the authors, which plays a central role in the climate and its variability.
