Labrador Sea Water in the Eastern North Atlantic. Part II: Mixing Dynamics and the Advective–Diffusive Balance
Publisher: American Meteorological Society
Abstract: Deep wintertime convection in the Labrador Basin produces Labrador Sea Water (LSW), which spreads throughout the North Atlantic. The LSW is not formed with constant characteristics but varies on decadal timescale. These ...
Labrador Sea Water in the Eastern North Atlantic. Part I: A Synoptic Circulation Inferred from a Minimum in Potential Vorticity
Publisher: American Meteorological Society
Abstract: A synoptic distribution of Labrador Sea Water (LSW) in the eastern North Atlantic is determined from a regularly sampled, but sparse (3° resolution), survey covering 39° to 54°N, 11° to 34°W during spring 1991. The core ...
Comments on “Decadal Changes in the North Atlantic and Pacific Meridional Overturning Circulation and Heat Flux”
Publisher: American Meteorological Society
Abstract: It is demonstrated that current level models, both with and without assimilation, generate too shallow an overturning in the North Atlantic (just like their predecessors) because they do not reproduce the descent of plumes ...
Timely Detection of Changes in the Meridional Overturning Circulation at 26°N in the Atlantic
Publisher: American Meteorological Society
Abstract: It is investigated how changes in the North Atlantic meridional overturning circulation (MOC) might be reliably detected within a few decades, using the observations provided by the RAPID-MOC 26°N array. Previously, ...
The Atlantic Overturning Circulation: More Evidence of Variability and Links to Climate
Publisher: American Meteorological Society
Decadal Changes in the South Indian Ocean Thermocline
Publisher: American Meteorological Society
Abstract: A significant change in properties of the thermocline is observed across the whole Indian Ocean 32°S section between 1987 and 2002. This change represents a reversal of the pre-1987 freshening and decreasing oxygen ...
Continuous Estimate of Atlantic Oceanic Freshwater Flux at 26.5°N
Publisher: American Meteorological Society
Abstract: he first continuous estimates of freshwater flux across 26.5°N are calculated using observations from the RAPID?MOCHA?Western Boundary Time Series (WBTS) and Argo floats every 10 days between April 2004 and October 2012. ...
Vertical Velocity Dynamics in the North Atlantic and Implications for AMOC
Publisher: American Meteorological Society
Overturning in the Subpolar North Atlantic Program: A New International Ocean Observing System
Publisher: American Meteorological Society
Abstract: or decades oceanographers have understood the Atlantic meridional overturning circulation (AMOC) to be primarily driven by changes in the production of deep-water formation in the subpolar and subarctic North Atlantic. ...
