Length Scales in a Rotating Stratified Fluid on the Beta Plane
Length Scales Beta Plane Rotating Stratified Fluid
2009/4/2
The relationships between vertical and horizontal length scales in a rotating stratified fluid on the beta plane are discussed in an attempt to unify the results of previous papers. The model is stead...
Trapped Coastal Waves on an Equatorial Beta Plane
Trapped Coastal Waves Equatorial Beta Plane
2009/2/23
This paper describes the zonally propagating wave modes of a homogeneous fluid on an equatorial beta-plane with linear bottom topography. The fluid is bounded above by a free surface and bounded below...
The dispersion relation is derived for trapped freely propagating barotropic long trench waves on a midlatitude β-plane. It is found that a critical wavenumber kc, which depends on trench orientation ...
This paper examines the motion and propagation of an isolated of anomalous water on a beta-plane, considered previously by Nof (1981). His perturbation analysis is extended to show the following:

3H and 3He in the Beta Triangle:Observations of Gyre Ventilation and Oxygen Utilization Rates
Gyre Ventilation Oxygen Utilization Rates
2009/1/7
Isopycnal maps of 3H–3He age (τ) with about 100 km resolution have been obtained for a 1000-km scale area in the eastern subtropical North Atlantic. The midscale texture of the maps is consistent with...
Generation of Mean Flows and Jets on a Beta Plane and over Topography
Mean Flows Jets Beta Plane
2008/12/18
This paper proposes and discusses mechanisms whereby mean flows and jets are produced by differential rotation and by topographic effects. It is shown that, in general, a mean gradient of potential vo...
Zonal Jets over Topography on a Beta-Plane, with Applications to the Kuroshio Extension over the Shatsky Rise
Zonal Jets Beta-Plane Kuroshio Extension Shatsky Rise
2008/12/16
The response of an initially zonal barotropic or baroclinic jet to an isolated seamount or a meridional ridge is investigated here using a three-dimensional primitive equation model with a free surfac...
Beta-Induced Translation of Strong Isolated Eddies
Beta-Induced Translation Strong Isolated Eddies
2008/12/10
Strong eddies on the β plane are considered within the framework of the one-layer primitive equations. The attention is focused on calculating the β-induced changes to the spatial structure of the edd...
A numerical model, with quasigeostrophic and barotropic dynamics, is used to study the forcing of mean flows by an unstable jet. The initially zonal jet has specified shape and transport at the wester...
The Antarctic Circumpolar Wave: A Beta Effect in Ocean–AtmosphereCoupling over the Southern Ocean
Antarctic Circumpolar Wave Southern Ocean Ocean–AtmosphereCoupling
2008/10/23
The Antarctic circumpolar wave (ACW) is a nominal 4-yr climate signal in the ocean–atmosphere system in the Southern Ocean, propagating eastward at an average speed of 6–8 cm s−1, composed of tw...
The Stability of Zonal Jets in a Rough-Bottomed Ocean on the Barotropic Beta Plane
Zonal Jets Rough-Bottomed Ocean Barotropic Beta Plane
2008/6/30
The author considers the stability of a barotropic jet on the beta plane, using the model of a “rough-bottomed ocean” (i.e., assuming that the horizontal scale of bottom irregularities is much smaller...
