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.

North Pacific Decadal Variability in the GEOS-5 Atmosphere-Ocean Model

TL;DR: In this article, the authors examined the mechanisms of the Pacific decadal oscillation (PDO) in the GEOS-5 general circulation model and found that the PDO is primarily forced by the Aleutian low through Ekman transport and surface fluxes, showing a red spectrum without any preferred periodicity.

Predicting bottom current deposition and erosion on the ocean floor

Daan Beelen, +1 more
TL;DR: In this article, three types of oceanographic data are integrated to predict thermohaline geostrophic bottom current deposition and erosion on the ocean floor, and the results of this analysis are displayed on a map that shows the distribution of zones of bottom current erosion and deposition.

On Quasigeostrophic Normal Modes in Ocean Models: Weakly Nonseparable Situation

TL;DR: In this article, the authors examined quasigeostrophic Rossby eigenmodes of homogeneous as well as stratified oceans, and showed that the widely used linearized boundary conditions give wrong results for lowfrequency modes.

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.
