Who We Are
US CLIVAR is a national research program with a mission to foster understanding and prediction of climate variability and change on intraseasonal-to-centennial timescales, through observations and modeling with emphasis on the role of the ocean and its interaction with other elements of the Earth system, and to serve the climate community and society through the coordination and facilitation of research on outstanding climate questions.
Our Research
The ocean plays a key role in providing a major long-term "memory" for the climate system, generating or enhancing variability on a range of climatic timescales. Understanding the ocean's role in climate variability is therefore crucial for quantifying and harnessing the predictability inherent to the Earth system. US CLIVAR-led research has played a substantial role in advancing understanding of, and skill in predicting climate variability and change.

Tracing the origins of equatorial Pacific biases in a coupled climate model
Wu and co-authors trace the origins of the eastern equatorial Pacific cold tongue bias in the NOAA Geophysical Fluid Dynamics Laboratory (GFDL) SPEAR coupled climate model (SPEAR_LO; Fig. 1d-f) using a set of mean-state correction experiments.

Upcoming Webinars
Usable Climate Risk Science Webinar Series
Date:
Title: Usable Climate Risk Science: April 28, 2026
Presenter(s):
Carolyn Kousky (Insurance for Good)
Ori Chegwidden (CarbonPlan)
During the fifth webinar in the Usable Climate Risk Science webinar series, we will be joined by Carolyn Kousky (Insurance for Good) who will discuss how we can create insurable communities. Ori Chegwidden (CarbonPlan) will discuss a new platform, Open Climate Risk, an explorer that maps wildfire risk across the contiguous United States.
