This research was supported by NSF through Grants 928473 and 928395, and by the Regional and Global Climate Modeling Program of the U.S. Department of Energy Office of Science. Los Alamos National Laboratory is operated by the Los Alamos National Security, LLC, for the National Nuclear Security Administration of the U.S. Department of Energy under Contract DE-AC52-06NA25396. For this study we used the Matlab routine EOF by David Kaplan (UCSC) and the ARFIT package by Schneider (Caltech) and Neumaier (University of Vienna). The CCSM 3.0 b30.009 data were obtained from the Earth System Grid. We thank three anonymous reviewers for their constructive comments.
