An ad hoc NRC committee will plan a workshop to bring together atmospheric and ocean climate experts to review the current science for decadal climate variability. Workshop participants will be asked to:
- examine our understanding of the processes governing decadal-scale variability in key climate parameters, observational evidence of decadal variability and potential forcings, and model-based experiments to explore possible factors affecting decadal variations;
- discuss key science, observing, and modeling gaps;
- consider the utility and accuracy of various observations for tracking long-term climate variability, anticipating the onset and end of hiatus regimes, and closing the long-term heat budget;
- consider the utility of hiatus regimes as a metric for evaluating performance of long-term climate models; and
- consider how best to communicate current understanding of climate variability, including potential causes and consequences, to non-expert audiences.
A summary of the workshop will be prepared by a designated rapporteur in accordance with institutional guidelines.
