Kelvin wave

[′kel·vən ‚wāv]
(oceanography)
An eastward-propagating internal gravity wave that crosses the Pacific Ocean along the equator and has no north-south velocity component.
A type of wave progression in relatively confined water bodies where, because of Coriolis force, the wave is higher to the right of direction of advance (in the Northern Hemisphere).

In addition, it is interesting to find that, in Figures 8(a), (b), (c), (d), the specular ranges significantly moves towards the scattered angles which are less than the specular angles, because the higher roughness can arise from the Kelvin wave elevation when ship speed increases, which seriously affects the slope distribution of surface.

[F.sub.h] V/[square root of (gh)] > 6 When this threshold is exceeded, the classical, linear Kelvin wave system is modified and specific, non-linear components of wakes frequently exist [31,32].

At the same time, the drop-off in the winds generates a fast-moving Kelvin wave that crosses the Pacific in 1 to 2 months.

The cloud layer at [equivalent] 12-16 km appears to be associated with a 10-day Kelvin wave that was identified by spectral analysis of radiosonde data at Koror, Republic of Palau (7[degrees]N, 134[degrees]E), and Chuuk, Federated States of Micronesia (7[degrees]N, 152[degrees]E).

A sudden relaxation of the trades in the central equatorial Pacific would then allow this warm water to "slosh back" toward the east in the form of an eastward-propagating equatorial Kelvin wave. (1)
The curious case of the El Nino that never happened: a perspective from 40 years of progress in climate research and forecasting
Seasonal averages during 2014 highlighted the El Nino-like signatures in this ENSO-neutral year (see section 4b), with the excitation of a downwelling Kelvin wave in the first quarter of the year associated with westerly winds bursts over the western equatorial Pacific (Fig.
