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.

Upcoming Webinars
Variations Webinar Series
Antonietta Capotondi, NOAA Physical Sciences Laboratory and University of Colorado / Cooperative Institute for Research in Environmental Sciences
Scott Powell, Naval Postgraduate School
The is the second webinar in a two-part series spotlighting emerging science and evolving needs in tropical Pacific observations critical for advancing Earth system predictions.
Process Study Webinar Series
Charlotte Demott, Colorado State University
This talk will summarize the findings of the ASTZ Study Group report and offer some early assessments of how ongoing and planned process studies harmonize with these recommendations.
