TLDR
The TOPEX/POSEIDON satellite altimeter has detected Rossby waves throughout much of the world ocean from sea level signals with ≲10-centimeter amplitude and ≳500-kilometer wavelength.Abstract:
Rossby waves play a critical role in the transient adjustment of ocean circulation to changes in large-scale atmospheric forcing. The TOPEX/POSEIDON satellite altimeter has detected Rossby waves throughout much of the world ocean from sea level signals with ≲10-centimeter amplitude and ≳500-kilometer wavelength. Outside of the tropics, Rossby waves are abruptly amplified by major topographic features. Analysis of 3 years of data reveals discrepancies between observed and theoretical Rossby wave phase speeds that indicate that the standard theory for free, linear Rossby waves is an incomplete description of the observed waves.read more

The Kinematics of Mesoscale Eddies from TOPEX/Poseidon Altimetry over the Subtropical Counter Current
TL;DR: In this paper, a case study was made for a cyclonic and an anticyclonic eddy, with time series of eddy kinematic parameters computed, showing that the cyclonic eddies survive for about 220 days and propagate westwards along over 22°N-24°N to reach the Kuroshio Current east coast of Taiwan.
Baroclinic Modeling of the South Pacific Gyre
TL;DR: In this article, the authors examined and filtered sea level changes at the Fort Denison tide gauge site in Sydney, Australia, in the context of decadal climate variability as represented by the Interdecadal Pacific======Oscillation index.

Detection of Rossby waves in ocean colour data
TL;DR: By producing longitude-time plots of the merged OCTS and SeaWiFS monthly composites the authors detect, at some latitudes, westward propagating signals whose characteristics are consistent with those expected for long-wavelength baroclinic Rossby waves.

The 1990–1995 El Niño‐Southern Oscillation Event: Longest on Record
TL;DR: In this article, the authors carried out several statisticaJ tests to assess the likelihood that the recent behavior of the Southern Oscillation (SO) is part of a natural decadal timescae variation.

TL;DR: The TOPEX/POSEIDON satellite as mentioned in this paper is the first space mission specifically designed and conducted for studying the circulation of the world's oceans and has been making observations of the global oceans with unprecedented accuracy since late September 1992.

Forcing of intraseasonal Kelvin waves in the equatorial Pacific
TL;DR: In this article, a model was proposed that suggests an ocean-atmosphere coupling by which zonal advection of SST feeds back to the atmosphere; the model duplicates the steplike advance of warm water and westerly winds across the equatorial Pacific at the onset of the El Nino of 1991-1992.

Implicit free‐surface method for the Bryan‐Cox‐Semtner ocean model
TL;DR: In this paper, the surface pressure reformulation of the Bryan-Cox-Semtner global ocean model was further improved by eliminating the rigid-lid approximation in favor of an implicit free-surface method for the barotropic mode.
