Atlantic Ocean

Schematic representation of the (a) atmospheric “non-frontal” and (b) atmospheric “frontal” components
October 4, 2018

New research illustrates that the key to recognizing the influence of the Gulf Stream and Kuroshio Extension on the seasonal mean and longer-term climate is through a proper understanding of how the ocean influences atmospheric fronts.

Multiple model mean correlation maps between the 10-year low-pass filtered AMOC index and AMV-related variables
June 22, 2018

Using both observations and simulations from multiple models, researchers show that most models underestimate the amplitude of low-frequency AMOC variability.

MOC time series at 34.5S
May 22, 2018

An international team of scientists used six years of simultaneous moored observations with satellite winds to produce a new MOC volume transport record for 34.5°S in the South Atlantic Ocean.

RAPID and MOVE array locations
May 9, 2018

Scientists have investigated differences between two arrays (at 16N and 26N) and found that both datasets show deep waters (below 1100 m) at the western boundary becoming fresher and less dense, but there remain discrepancies in the methods measuring ocean circulation. 

hurricane intensity
March 19, 2018

Research shows that SST may explain a significantly smaller percentage of the variance in tropical cyclone intensification in the Atlantic as compared to the western North Pacific and eastern-central Pacific.

Decadal-scale correlations between northern Gulf of Mexico and global sea surface salinity as well as continental precipitation
February 28, 2018

Researchers show that weakened surface ocean circulation coincides with precipitation during the Little Ice Age and is consistent with little-to-no changes in the larger Atlantic meridional overturning circulation. 

Atlantic hurricanes
December 11, 2017

Using observations and a coupled Earth system model, a new study shows that the decline of the Atlantic major hurricane frequency during 2005–2015 is associated with a weakening of the AMOC.

September 18, 2017

The Arctic sea ice decline may explain the suggested slow-down of the Atlantic meridional overturning circulation and the persistence of the Warming Hole.

Three-dimensional pathways of deep water upwelling from the Atlantic Ocean over Southern Ocean topography
August 16, 2017

A new study combines ocean observations with three state-of-the-art ocean models, revealing the full three-dimensional pathway of deep water to the surface of the Southern Ocean for the first time.

modeling hindcasts and projections of sea level rise and overturning circulation
August 4, 2017

A new study helps clarify how past and future coastal sea level changes are related to local winds and large-scale ocean circulation.
