US Climate Variability and Predictability Program

US CLIVAR Climate Variability and Predictability Program

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.

Abstract submission form now open

Submit your abstract for a poster presentation at the 2022 OCB/US CLIVAR Ecological Forecasting Workshop. Deadline for submissions is January 21, 2022.

Variability in Pacific Sardine recruitment is related to spring sea surface temperature in the California Current.

Ecological Forecasting Workshop blog

Leading up to the workshop, the Scientific Organizing Committee is publishing blog posts about ecological forecasting science, stakeholders and applications, research activities, results, and challenges. Check out the first post by Victoria Coles.

The Pattern Effect: Coupling of SST Patterns, Radiative Feedbacks, and Climate Sensitivity Workshop

Scheduled for May 10-13, 2022. The workshop's goal is to advance our understanding of the coupling between surface temperatures and radiative feedbacks and the origin and timescales of surface temperature pattern evolution.
