Deviations from normal sea surface temperatures (left) and sea surface heights (right) at the peak of the 2009-2010 central Pacific El Niño, as measured by NOAA polar orbiting satellites and NASA's Jason-1 spacecraft, respectively. The warmest temperatures and highest sea levels were located in the central equatorial Pacific. Image credit: NASA/JPL-NOAA

Madden Julian Oscillation- › 30-90 day cycle of eastward propagating
deep convection› Strong MJO have been known to cause
intense breakdown of Walker circulation resulting in a Kelvin wave across the equator causing the rapid onset of an El Nino event(Ie. 1982 El Nino)
