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.

Observed ocean-atmosphere anomaly patterns multi-year La Niña event

New findings could improve our ability to predict both the strength and duration of US droughts caused by La Niña.

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.

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. 

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. 

Monthly changes strength of the zonal flow
July 6, 2017

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.
