Great thanks to Naomi Naik for assistance in running the INC model; Jeffrey Shaman for his patience, attention, and advice; and Donna Witter for her encouragement and support. The insight gained through interactions at the March 2000 ENSO conference and NCAR Summer Colloquium, 2000 has proved invaluable. Support for this research was provided by the National Science Foundation under Grant OCE 9819538 and ATM 9986072.
