The modeling groups and the Program for Climate Model Diagnosis and Intercomparison (PCMDI) and the WCRP’s Working Group on Coupled Modeling (WGCM) are acknowledged for their roles in making available the WCRP CMIP3 multimodel dataset. Support of this dataset is provided by the Office of Science, U.S. Department of Energy. Dr. Benno Blumenthal was instrumental in making the PCDMI data accessible via the IRI Data Library. The South African Weather Service kindly provided the daily maximum temperature data and the help of John del Corral and Simon Mason is gratefully acknowledged for making them accessible. Comments on the original version of this manuscript by Tony Barnston and three anonymous reviewers are also very much appreciated. This work was funded by a Small Grant for Exploratory Research from the National Science Foundation (NSF), Grant NSF-ATM 07-39256, and from the National Oceanic and Atmospheric Administration (NOAA) through Grant NA05OAR4311004.
