A Southern Ocean polynya
November 2, 2017

Researchers observed a natural, regular, multidecadal oscillation between periods of Southern Ocean open-sea convection, which can act a release valve for the ocean’s heat, and non-convective periods.

As the decadal ENSO cycle transitions to a warm phase, a new study expects accelerated global warming and a “hiatus” in Hadley Cell expansion.

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.

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. 

Differences between preindustrial (left) and LGM (right) ocean circulation
July 26, 2017

A recent study investigates the drivers of changes in deep ocean circulation across a range of modern and Last Glacial Maximum (~21000 years ago) climate modeling simulations, revealing biases in Antarctic sea ice formation.

Looking at modeling simulations, researchers explore how various characteristics of the mid-latitude atmospheric circulation evolve over the 21st-century and find that changes are sector-dependent.

Ocean Circulation Plays an Important Role in Absorbing Carbon from the Atmosphere, NASA GSFC
June 29, 2017

NASA and MIT scientists found that gases are more easily absorbed over time than heat. As the Atlantic Meridional Overturning Circulation (AMOC) slows down, the ocean absorbs less of both atmospheric gases and heat, though its ability to absorb heat is more greatly reduced.

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.
