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. 

The Observational Large Ensemble (Obs-LE) can be used to assess the relative roles of internal variability and anthropogenic influence on 50-year trends in (a-b) temperature and (c-d) precipitation over land.
August 29, 2018

Researchers have developed a complementary approach to creating ensembles for seasonal-average temperature and precipitation over land that can also be used to study internal variability.

Response in wintertime surface air temperature and surface wind to imposed RCP8.5 sea ice loss over the Barents-Kara sea
August 13, 2018

A new Arctic and mid-latitude interaction study highlights the necessity to use stratosphere-resolving models when identifying the warm Arctic–cold Siberia pattern.

August 8, 2018

Observed Southern Hemisphere summer and fall trends of tropical expansion are well captured in model simulations of the late 20th and early 21st centuries, consistent with the roles of increasing greenhouse gases and stratospheric ozone depletion in driving poleward circulation shifts during these seasons.

SST anomalies in the boreal winter
August 3, 2018

A coupling in Pacific dynamics has been increasing in observational records between 1950–2017, leading to more frequent occurrences of multi-year warm events like the marine heatwave of 2014–15

Megadrougth schematic and teleconnections
July 16, 2018

To improve estimates of risks associated with megadroughts, researchers look at improving the understanding of ENSO/AMO behavior, their teleconnections, and their response to volcanic eruptions in climate models.
