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.

Beyond wind-driven mixing: New insights into vertical exchange at a coastal front
Körner et al. (2026) show that symmetric instability (SI) efficiently transport oxygen and heat between surface and bottom waters in the northern Gulf, ventilating low-oxygen waters more effectively than turbulence alone.
Simple ocean-based model shows El Niño forecast skill and points to a strong event ahead
Wang et al. (2026) present the Wyrtki CycloStationary Linear Inverse Model (Wyrtki-CSLIM), which leverages Wyrtki and Hasselmann memory to demonstrate that skillful ENSO forecasts can be generated up to 15 months in advance.
