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.

Research Highlights
A recent study uses large ensembles of an idealized general circulation model to demonstrate how episodic surface warming in the Arctic can lead to delayed responses in the stratosphere that persist for about two months, even in the absence of stationary waves.
Comparison of fossil corals samples with modern corals showed that the recent ENSO intensification was quite apparent – the most recent 20 years was stronger than almost all 20-year periods measured over the entire preindustrial fossil coral dataset.
Under exclusive CO2 forcing, climate models predicted twice as much Hadley cell expansion in the Southern Hemisphere as in the Northern Hemisphere. The finding was robust across models and all seasons except boreal fall.
A new version 3 of the NOAA-CIRES-DOE 20th Century Reanalysis (20CRv3) recreates a 180-year history of temperature, precipitation, winds, humidity, and many other variables from below the land surface to the top of the atmosphere.
