Funding by NOAA/GCIP Grant NA77RJ0453 made this work possible. Additional funding from NSF Grant ATM-99-01110, NASA Grant NAG5-8292, and the California Applications Project (NOAA Grant NA17RJ1231) contributed to this research effort. We thank Tim Barnett and Rick Lawford for their personal encouragement and intellectual input. Tim Barnett conceived the original idea for hybrid seasonal prediction. Conversations with Lisa Goddard and Tony Westerling stimulated the creative processes. Thanks are also due to Jon Eischeid for providing the precipitation data and to Mary Tyree and Larry Riddle for help with data processing. NCEP–NCAR reanalysis data were provided by the NOAA–CIRES Climate Diagnostics Center, Boulder, Colorado, via their Web site at http://www.cdc.noaa.gov/. IRI provided their AGCM base runs. Critical comments by Francis Zwiers and two anonymous reviewers improved the manuscript.
