The Madden-Julian oscillation (MJO), oceanic Kelvin waves, and the EL Nino/Southern Oscillation (ENSO) follow a systematic pattern of feedbacks that control the amplitude, structures, and variability of each mode. We present results of a regression model that clearly reveals the structure of the forcing of the Kelvin waves and how it changes with ENSO phase. Results indicate that the structure of the forcing changes with the ENSO cycle in a manner that forces the progression of the cycle itself.
