Tropical Pacific Observing System (TPOS)
Process Studies Webinar Series

For questions about the webinar series, please contact Jose Algarin.

The NOAA Climate Variability and Predictability (CVP) Program is hosting a webinar series on the Tropical Pacific Observing System (TPOS) Pre-Field Modeling Studies that will highlight the recent results from the CVP-funded projects. The goal of these modeling studies is to refine the current scientific understanding of the equatorial Pacific climate system, with a specific focus on two process studies identified in the TPOS 2020 First Report, “Pacific Upwelling and Mixing Physics (PUMP)” and “Air–sea Interaction at the eastern edge of the Warm Pool”. Their results will assist in the planning of future field campaigns.

The webinar series will have five sessions (running on a biweekly or weekly basis) starting on Thursday, September 22, 2022 and ending on Thursday, November 10, 2022. Each session will be one-hour long, and feature two, 20-minute presentations. There will be time for questions from the audience.

All sessions will be recorded and preserved in this page. We look forward to your participation in this series!
