Using a local energetics framework, Brizuela et al. (2025) find that 20-50% of equatorial Pacific upwelling is not driven by local winds but by potential energy stored in the tropical thermocline.

The 2025 US CLIVAR Summit, held in Boulder this past July, included three plenary sessions and 13 breakouts on a range of pressing climate variability and change science topics. The report is now available.

Villas Bôas, Marechal, and Bohé (2025) leverage data from SWOT’s Ka-band Radar Interferometer (KaRIn) to explore the first-ever two-dimensional (2D) maps of significant wave height (Hs) at kilometer-scale resolution. These novel observations enable detailed investigation of how waves, winds, and currents interact across a wide range of scales and ocean conditions.

The joint OCB/US CLIVAR Pathways Connecting Climate Changes to the Deep Ocean Workshop report reviews the discussions and recommendations of the workshop that took place April 2024. Key topics include fast and slow pathways connecting the ocean surface to deep and methods for observing and modeling these pathways.

Hosted by the US CLIVAR Working Group on Accelerating Research on the Scientific Foundations of Regional Climate Risk Information, this webinar series explores the growing demand for actionable information on climate hazards and risks.

Chen et al. (2025) employs large-eddy simulations to demonstrate how small-scale SST variations can increase trade cumulus cloud formation. The authors argue that locally enhanced convective updrafts lead to an increase in cloudiness near the cloud base, which occurs downwind of the maximum SST warm anomaly as the SST anomaly gets sharper. Their results suggest that improving model parameterizations could reduce uncertainty in climate models by better capturing how subcloud turbulent mixing, convective mass flux, and cloud-base cloudiness respond to small-scale SST anomalies in the tropical oceans.

The 2025 US CLIVAR Summit, held in Boulder this past July, featured three plenary sessions and thirteen breakout sessions covering a wide range of pressing climate variability and change topics. Presentations from the sessions are available on the Summit agenda.
