This study is supported by the Office of Science (BER), U.S. Department of Energy. The 20CR and NCEP-1 data were obtained from the NOAA ESRL/PSD data portal (http://www.esrl.noaa.gov/psd). We acknowledge the World Climate Research Programme’s Working Group on Coupled Modelling, which is responsible for CMIP, and we thank the climate modeling groups (listed in Tables 1 and 2 of this paper) for producing and making available their model output. For CMIP the U.S. Department of Energy’s Program for Climate Model Diagnosis and Intercomparison provides coordinating support and led development of software infrastructure in partnership with the Global Organization for Earth System Science Portals. The authors appreciate detailed comments from three reviewers that helped improve the manuscript.
