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

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.

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

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.

Researchers found that atmospheric rivers that impact the West Coast contain more tropical moisture than average, indicating that long-distance transport of tropical moisture does occur.
