The Prediction,Verification,and Significance of Flank Jets at Mid-Ocean Ridges
Prediction Verification Significance Flank Jets Mid-Ocean Ridges

2015/7/14
One aspect of ocean flow over mid-ocean ridges that has escaped much attention is the capacity of a ridge to convert oscillatory flows into unidirectional flows. Those unidirectional flows take the fo...
Upwelling and Coastal Jets in a Continuously Stratified Ocean
Coastal Jets Continuously Stratified Ocean Upwelling
font style='font-size:12px;'>
2009/4/2
A simple, linear, two-dimensional, f-plane model of coastal upwelling in a continuously stratified ocean is investigated. The transient response of the fluid to an impulsively applied alongshore wind ...

Baroclinic Coastal Jets Lake Ontario
font style='font-size:12px;'>
2009/3/26
Coastal current observations taken at five locations in Lake Ontario during IFYGL, in periods of summer stratification, are presented and interpreted in terms of a linear dynamical model. Wind-stress ...

Coastal Jets Upwelling Bounded Basins
font style='font-size:12px;'>
2009/3/24
The relationship between coastal upwelling and coastal long-short currents is studied in a simple model of a continuously stratified fluid in a closed basin on the f-plane. It is shown that the coasta...
Nonlinear Coastal and Equatorial Jets
Nonlinear Coastal Equatorial Jets
font style='font-size:12px;'>
2009/2/13
Nonlinearities weaken westward equatorial jets and cause them to be shallower and broader than their linear counterparts. Nonlinear eastward equatorial jets, on the other hand, are more intense, deepe...

Radiating Instabilities Thin Baroclinic Jets
font style='font-size:12px;'>
2009/2/6
The linear stability of thin, quasi-geostrophic, two-layer zonal jets on the β-plane is considered. The meridional structure of the jets is approximated in such a way as to allow an exact dispersion r...
Zonal Penetration Scale of Model Midlatitude Jets
Zonal Penetration Scale Model Midlatitude Jets
font style='font-size:12px;'>
2009/1/16
All available observations indicate that the most energetic time-dependent currents are located in the vicinity of intense large-scale oceanic current systems. This characteristic is also a basic prop...
Coastal Jets in the Lower Atmosphere
Coastal Jets Lower Atmosphere
font style='font-size:12px;'>
2009/1/15
Low-level winds over land-ocean boundaries are generally alongshore. Two types of forcing that generate alongshore jets in the lower atmosphere are considered here, using as simple a model as possible...
Nonlinear Waves and Coherent Vortex Structures in Barotropic β-plane Jets
Nonlinear Waves Barotropic β-plane Jets Coherent Vortex Structures
font style='font-size:12px;'>
2009/1/8
We examine the nonlinear evolution of barotropic β-plane jets on a periodic domain with a pseudospectral. A calculation of the linear growth rate yields an infected U-shaped curve on the β versus k0 p...
Dynamics of Deep Thermocline Jets in The POLYMODE Region
Deep Thermocline Jets POLYMODE Region
font style='font-size:12px;'>
2009/1/8
We present the study of a series of very energetic events, which occur in the 360 days of the Polymode Synoptic Dynamics Experiment dataset. The method consists of the assimilation of data by a quasi-...

2009/1/6
Hydrographic measurements in the southeastern Levantine basin are analyzed, and the climatological water masses of the region and their seasonal variations are identified. We observe the formation of ...
Meander Evolution on Piecewise-Uniform, Quasi-geostrophic Jets
Meander Evolution Piecewise-Uniform Quasi-geostrophic Jets
font style='font-size:12px;'>
2008/12/24
A variety of simple, two-layer representations of a quasi-geostrophic jet along a vorticity front are initialized with a simple meander. The subsequent evolution of the jet is followed and related to ...
Zonal Penetration Scale of Midlatitude Oceanic Jets
Zonal Penetration Scale Midlatitude Oceanic Jets Gulf Stream
font style='font-size:12px;'>
2008/12/22
It is shown that subtle changes in the velocity profile across the seaward extension of midlatitude jets, such as the Gulf Stream, can lead to dramatic changes in the zonal-penetration scale. In parti...
The Drift of Midocean Jets
Midocean Jets nonlinear frontal jets

2008/12/19
The migration of nonlinear frontal jets is examined using an inviscid “reduced gravity” model. Two cases are considered in detail. The first involves the drift of deep jets situated above a sloping bo...
