چکیده
Abstract The Atlantic Meridional Overturning Circulation (AMOC) is a tipping component of the climate system, with quasi-global impact. Several numerical and observational studies emphasized two modes AMOC variability, characterized by distinct sea surface temperature patterns. One associated centennial changes, Trend Mode, other Multidecadal Oscillation (AMO). origin different manifestations these it not fully understood. Using data an ocean general circulation model we present evidence that, whereas Mode mainly linked deep water formation in Nordic Seas North cell centered at 50° N, AMO related Labrador Irminger overturning 20° N. In combination previous studies, results imply that main route increasing atmospheric CO 2 concentration influence on passes through reflected subpolar meridional cell.

Tracing the flow of North Atlantic Deep Water using chlorofluorocarbons
Chlorofluorocarbon (CFC) and hydrographic data collected in the North Atlantic in the late 1980s and early 1990s are used to confirm and add to earlier work on the large-scale circulation pathways and timescales for the spreading of North Atlantic Deep Water (NADW) components and how these components relate to the hydrographic structure. Throughout he western North Atlantic, high CFC concentrat...
متن کاملNorth Atlantic Deep Water Production during the Last Glacial Maximum
Changes in deep ocean ventilation are commonly invoked as the primary cause of lower glacial atmospheric CO2. The water mass structure of the glacial deep Atlantic Ocean and the mechanism by which it may have sequestered carbon remain elusive. Here we present neodymium isotope measurements from cores throughout the Atlantic that reveal glacial-interglacial changes in water mass distributions. T...
متن کاملNorth Atlantic Deep Water formation inhibits high Arctic contamination by continental perfluorooctane sulfonate discharges
Perfluorooctane sulfonate (PFOS) is an aliphatic fluorinated compound with eight carbon atoms that is extremely persistent in the environment and can adversely affect human and ecological health. The stability, low reactivity, and high water solubility of PFOS combined with the North American phaseout in production around the year 2000 make it a potentially useful new tracer for ocean circulati...
متن کاملThe Role of North Atlantic Deep Water Formation in an OGCM’s Ventilation and Thermohaline Circulation*
Two coarse-resolution model experiments are carried out on an OGCM to examine the effects of North Atlantic Deep Water (NADW) formation on the thermohaline circulation (THC) and ventilation timescales of the abyssal ocean. An idealized age tracer is included to gauge the ventilation in the model. One experiment is forced with the present-day climatology, the other has a negative salinity anomal...
متن کاملCorrigendum: Recent increases in Arctic freshwater flux affects Labrador Sea convection and Atlantic overturning circulation
The Atlantic Meridional Overturning Circulation (AMOC) is an important component of ocean thermohaline circulation. Melting of Greenland's ice sheet is freshening the North Atlantic; however, whether the augmented freshwater flux is disrupting the AMOC is unclear. Dense Labrador Sea Water (LSW), formed by winter cooling of saline North Atlantic water and subsequent convection, is a key componen...
