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. 

Zonally averaged multi-model average shortwave low cloud feedbacks
March 25, 2020

Zelinka and coauthors compared ECS values derived from CO2 quadrupling experiments conducted with CMIP6 and CMIP5 models and found that the latest models warm more than their predecessors by about 0.5˚C. The primary culprit for the enhanced warming was shown to be clouds.

ean 2014-2016 sea surface temperature anomaly (SSTa) in the Northeast Pacific
February 28, 2020

A recent study explored sea surface temperature anomaly forecasts from an ensemble of eight global climate prediction systems contributing to NMME and found that predictability of warm temperature anomalies off the US West Coast was conditional on which process was driving the temperature anomalies in different phases of the heatwave.

Estimates of interannual variability from new and published coral records from the northern Line Islands
February 13, 2020

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.

January 22, 2020

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.

Multi-model mean evolution of the Hadley cell edge (defined by streamfunction at 500 hPa) in the 1 percent CO2 increase simulations. Copyright AGU.
January 14, 2020

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.
