A **equatorial Kelvin wave** is a type of oceanic wave that may play an important role in the [[ENSO]] cycle. See: * [Equatorial Kelvin wave](http://en.wikipedia.org/wiki/Kelvin_wave#Equatorial_Kelvin_wave), Wikipedia. Quoting: > The equatorial zone essentially acts as a waveguide, causing disturbances to be trapped in the vicinity of the equator, and the equatorial Kelvin wave illustrates this fact because the equator acts analogously to a topographic boundary for both the Northern and Southern Hemispheres, making this wave very similar to the coastally-trapped Kelvin wave.
