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. 

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.

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.

Monthly SST anomalies 1920–2016
August 30, 2017

New research confirms that links between warm and cool years in the California Current System and El Niño are important but imperfect.
