A Joint Modeling Study of El Niño Is Under Way

Drs. Barry Klinger and Julian McCreary, of the OC, and Richard Kleeman, of Lamont-Doherty Earth Observatory, Palisades, NY, are busy working on a very hot topic these days. They are modeling decadal variations of El Niño. The project is being spon- sored by the National Oceanic and At- mospheric Administration (NOAA). According to Klinger, the motiva- tion for their work is the fact that roughly every 3 to 7 years there is an El Niño, but there seems to be a longer scale. “Over 10 years you might get a series of strong ones, then for the next 10 years you might get weak ones. We have a theory that might explain why.” His theory goes back to some early work with McCreary and Peng Lu, which “connects what the ocean is do- ing outside the tropics with what is happening at the equator. When an El Niño occurs,” Klinger explains, “it basi- cally gets rid of a region of relatively cold water in the eastern equatorial Pacific. Why is there cold water at the Drs.
