Quantifying the Agreement Between Observed and Simulated Extratropical MModes of Interannual Variability
Science
Exploring several viable approaches, a new analysis method, the “Common Basis Function” approach, has been implemented. Our approach indicates that modern ESMs (CMIP5) are performing better than hitherto suggested, within many cases the dominant bias being an overestimation of variability.
Impact
This study provides robust metrics to compare simulated interannual to interdecadal variability with observations that were previously lacking. This will enable a more rigorous examination of simulated variability and help improve our understanding of ESM behavior.
Summary
Develop an innovative set of objective tests and metrics to gauge how well earth system models simulate observed modes of extratropical variability.
