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.

Global statistical space-time scales of oceanic variability estimated from the TOPEX/ POSEIDON altimeter data

TL;DR: In this paper, a three-dimensional (space-time) correlation function with an anisotropic directional dependence is used to reveal the space-time scales and propagations of the ocean variabilities and statistical errors in the altimeter data.

Circulation and multiple-scale variability in the Southern California Bight

TL;DR: In this article, the authors applied the Regional Oceanic Modeling System (ROMS) to the Southern California Bight (SCB) circulation and its multiple-scale variability.

Taiwan Current (Kuroshio) and Impinging Eddies

TL;DR: In this paper, the sea level differences (SLD) across the Taiwan Current (Kuroshio) in the East Taiwan Channel (ETC) are utilized in order to examine the possible implication of eddies in the Taiwan current transport.

Aerogeophysical measurements of collapse-prone hydrothermally altered zones at Mount Rainier volcano

TL;DR: In this article, the authors present helicopter-borne electromagnetic and magnetic data, combined with detailed geological mapping, to show that appreciable thicknesses of mostly buried hydrothermally altered rock lie mainly in the upper west flank of Mount Rainier.

ENSO to multi-decadal time scale changes in East Australian Current transports and Fort Denison sea level: Oceanic Rossby waves as the connecting mechanism

TL;DR: In this article, the authors demonstrate a statistically significant relationship between interannual to decadal time scale variations in estimates of the EAC transport changes and east coast sea level measured at the high-quality, decades-long record Fort Denison tide-gauge in Sydney Harbour, Australia.

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.
