Editing Antarctic Circumpolar Wave (section)

== History of  the concept ==
Although the "wave" is seen in [[temperature]], [[atmospheric pressure]], [[sea ice]] and ocean height, the variations are hard to see in the raw data and need to be filtered to become apparent. Because the reliable record for the [[Southern Ocean]] is short (since the early 1980s) and [[signal processing]] is needed to reveal its existence, some [[climatologist]]s doubt the existence of the wave. Others accept its existence but say that it varies in strength over decades.<ref>{{Harvnb|Connolley|2002|loc=[2]}}</ref>

The wave was discovered simultaneously by {{Harvnb|White|Peterson|1996}} and {{Harvnb|Jacobs|Mitchell|1996}}. Since then, ideas about the wave structure and maintenance mechanisms have changed and grown: by some accounts it is now to be considered as part of a global [[El Niño Southern Oscillation|ENSO]] wave.<ref>{{Harvnb|Connolley|2002|loc=Introduction}}</ref>
