Talk:Equatorial wave

Matsuno, T. 1966: Quasi-geostrophic motions in the equatorial area. J. Met. Soc. Japan, 44, 25–43. http://www.journalarchive.jst.go.jp/english/jnlabstract_en.php?cdjournal=jmsj1965&cdvol=44&noissue=1&startpage=25 --Masudako (talk) 13:49, 21 October 2010 (UTC)Reply

The article says "Equatorial waves are ocean waves trapped close to the equator, meaning that they decay rapidly away from the equator, but can propagate in the longitudinal and vertical directions". Later it says "their wavelength in the zonal (east-west) direction". Q. Is longitudinal correct in view of these waves being trapped at the Equator and having zonal wavelength? "Zonal" is east-west, latitudinal. The source (p394) does mention "longitudinal" but it appears to be with respect to atmospheric waves that can occur in conjunction with the oceanic waves. 78.144.72.141 (talk) 22:38, 4 September 2014 (UTC)Reply

I'm not familiar enough with this topic to be confident in making substantive changes to this article, but there seems to be some ambiguity as to what kind of waves the article is about. I've tried my best to list the possible ambiguities below in the hope that someone more familiar will be able to clarify things:

• The first and last sentences of the lead mention only ocean waves, while the sentences between these two discuss both atmospheric and oceanic equatorial waves.
• The "Equatorial Rossby and Rossby-gravity waves" section appears to be about atmospheric waves (mentions of their discovery in the stratosphere/reference to wind components in the equations).
• The next section, "Equatorial Kelvin waves," again refers to winds in the equations, but also alludes to oceanic waves (propagation along the coast/same speed as shallow-water gravity waves).
• The ENSO section looks like it's mostly about the ocean, and then discusses atmosphere-ocean coupling.

Also, the "Equatorial Rossby/Rossby gravity wave" section mentions a "fluid of uniform depth H." I don't think H is mentioned anywhere else in the article except to compare it to "h" in the very last sentence of the article.
