Bistability of the Atlantic overturning circulation in a global climate model and links to ocean freshwater transport
The possibility of a rapid collapse in the strength of the Atlantic meridional overturning circulation (AMOC), with associated impacts on climate, has long been recognized. The suggested basis forExpand

History matching for exploring and reducing climate model parameter space using observations and a large perturbed physics ensemble
We apply an established statistical methodology called history matching to constrain the parameter space of a coupled non-flux-adjusted climate model (the third Hadley Centre Climate Model; HadCM3)Expand

Where do winds drive the Antarctic Circumpolar Current
The strength of the Antarctic Circumpolar Current (ACC) is believed to depend on the westerly wind stress blowing over the Southern Ocean, although the exact relationship between winds andExpand

Spin-up and adjustment of the Antarctic Circumpolar Current and global pycnocline
A theory is presented for the adjustment of the Antarctic Circumpolar Current (ACC) and global pycnocline to a sudden and sustained change in wind forcing. The adjustment timescale is controlled byExpand

SUSTAINED MONITORING OF THE SOUTHERN OCEAN AT DRAKE PASSAGE: PAST ACHIEVEMENTS AND FUTURE PRIORITIES
Drake Passage is the narrowest constriction of the Antarctic Circumpolar Current (ACC) in the Southern Ocean, with implications for global ocean circulation and climate. We review the long-termExpand

An event-based approach to understanding decadal fluctuations in the Atlantic meridional overturning circulation
Abstract Many previous studies have shown that unforced climate model simulations exhibit decadal-scale fluctuations in the Atlantic meridional overturning circulation (AMOC), and that thisExpand

Remote forcing of the Antarctic Circumpolar Current by diapycnal mixing
[1] We show that diapycnal mixing can drive a significant Antarctic Circumpolar Current (ACC) volume transport, even when the mixing is located remotely in northern-hemisphere ocean basins. In theExpand

A Model of the Ocean Overturning Circulation with Two Closed Basins and a Reentrant Channel
AbstractZonally averaged models of the ocean overturning circulation miss important zonal exchanges of waters between the Atlantic and Indo-Pacific Oceans. A two-layer, two-basin model that accountsExpand

Early warning signals of Atlantic Meridional Overturning Circulation collapse in a fully coupled climate model
The Atlantic Meridional Overturning Circulation (AMOC) exhibits two stable states in models of varying complexity. Shifts between alternative AMOC states are thought to have played a role in pastExpand
