This newly released workshop report provides a summary of the workshop as well as key recommendations.

A set of practical strategies and lessons learned to help guide planning and implementation of future process studies within the climate science community.

Save the date for the Tropical Pacific Observing Needs Workshop, May 24-26, 2021. This workshop will gather community input on the types of Tropical Pacific ocean and atmosphere observations needed to advance understanding.

Requests are now being accepted for new US CLIVAR-sponsored working groups for 2021. Submissions are encouraged from the US climate science community. All documents must be submitted by October 16, 2020. The next call for working groups will be in September 2021.

Requests are now being accepted for US CLIVAR-sponsored workshops. Submissions are encouraged from the US climate science community and their collaborators. All documents must be submitted by September 25. The next call for workshops will be in spring 2021. 

We showcase new applications of large ensembles to the understanding of climate variability and change on regional and decadal scales. These articles, written by early-career researchers at the forefront of their fields, span a range of emerging topics. 

The Changing Width of the Tropical Belt Working Group was formed in 2016 to further the understanding of new insights that call into question the prevailing view about the nature and causes of changes in the width of the tropics. Read about the impacts and activities of the Working Group and the International Space Science Institute (ISSI) Tropical Width Diagnostics Intercomparison Project on this topic in the recently published BAMS paper, "Tropical Widening: From Global Variations to Regional Impacts."

Recently published in BAMS, "Current and Emerging Developments in Subseasonal to Decadal Prediction" outlines commonalities in the prediction of weather and climate across time scales and Earth system components, and through the value cycle from basic research to operational delivery.
