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.

Nonlinear Rossby waves off California

TL;DR: In this article, a new interpretation of SSH anomalies propagating in the California Current System as weakly nonlinear Rossby waves (RWs) is suggested, and a transition from a SSH field dominated by waves to a turbulent-like field was detected in the saturation regime.

On the Observability of Oceanic Gyres

TL;DR: In this paper, the observability of a stratified ocean in a square flat basin on a midlatitude beta plane was examined. And the authors determined an observability Gramian (a symmetric matrix) for flows in an inviscid interior, in frictional boundary layers, and in a closed basin.

Combining multiple altimeter missions

TL;DR: In this paper, a least square analysis of the mean T/P SSH determines the portion of the Geographically Correlated Orbit Error (GCOE) that may be observed through crossover differences and removes this portion of GCOE.

Development and Assessment of the Systematically Merged Pacific Ocean Regional Temperature and Salinity (SPORTS) Climatology for Ocean Heat Content Estimations

TL;DR: In this paper, a systematically merged Pacific Ocean Regional Temperature and Salinity (SPORTS) was created to estimate ocean heat content (OHC) for tropical cyclone (TC) intensity forecasting and other applications.

Tropical oceanic intraseasonal variabilities associated with central Indian Ocean mode

TL;DR: In this article, the dynamics of tropical oceanic ISVs associated with the Central Indian Ocean (CIO) mode were analyzed using reanalysis products and observations, and a complete heat budget analysis showed that intraseasonal SST anomalies which propagate westward from the eastern to the central tropical Indian Ocean during the CIO mode are mainly attributable to zonal thermal advection.

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.

TOPEX/POSEIDON mission overview

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.
