Research Highlights

US CLIVAR aims to feature the latest research results from the community of scientists participating in our interagency-sponsored projects, working groups, panels, science teams, and workshops. Check out the collection of research highlights below and sort by topic on the right. 

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
November 28, 2017

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.

monthly-mean analysis of oxygen isotopes in precipitation and gross primary productivity
October 25, 2017

The most extreme increases in the oxygen 18-to-16 ratio over the last fifty thousand years occur immediately after Heinrich events, strongly suggesting that tropical rainfall shifted south in response to Heinrich events.

modes of the Hadley cell and ENSO
September 29, 2017

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