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.

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

Researchers have developed a state-of-the-art drought and wildfire prediction system, showing the multi-year predictive skills of drought and wildfire conditions beyond the typical timescale of seasonal climate forecast models. 

Precipitation differences between the positive and negative AMV
June 14, 2017

A multi-model simulation study shows that Atlantic Multidecadal Variability warming drives a modification of the Walker Circulation that creates precipitation anomalies over the whole tropical belt. 

SAMOC time series at four latitudes in the South Atlantic
May 8, 2017

A new study reconstructs a century-long South Atlantic Meridional Overturning Circulation index, from 1870 to present, finding it is highly correlated to the observational-based SAMOC time series and the Interdecadal Pacific Oscillation is the leading mode of variability.

Buoyancy frequencies
March 16, 2017

A recent study highlights results obtained from an aircraft ocean survey that targeted a large warm core eddy in the eastern Caribbean Sea, where upper ocean measurements are crucial to understanding the complexities of heat and moisture transfer during the passage of tropical cyclones.

AMOC RCP4.5 and 8.5
January 19, 2017

A new study shows that the AMOC is more sensitive to warming, including changes in the atmospheric hydrological cycle, than Greenland Ice Sheet melting. However, Greenland Ice Sheet melt further increases the projected AMOC weakening.

Hurricanes more likely to weaken along the US coast during active periods
January 6, 2017

A new study shows that when conditions in the deep tropics are good for hurricane intensification, they are bad along the US coast. This sets up a barrier around the US coast during active hurricane periods that inhibits hurricanes from strengthening and usually causes them to weaken.

Agulhas leakage, not salinity, linked to the Atlantic meridional circulation slowdown
December 28, 2016

A new study concludes that the likely source of changes in heat that caused the recent slowdown in the AMOC was from a decrease in the Agulhas Leakage and that changes in convection in the subpolar North Atlantic was an unlikely contributor.
