On the Generation of Baroclinic Rossby Waves in the Ocean by Meteorological Forces
Publisher: American Meteorological Society
Abstract: The generation of baroclinic Rossby waves in a continuously stratified ocean by fluctuating fields of wind stress, buoyancy flux and atmospheric pressure at the sea surface is studied by means of boundary layer theory. The ...
On the Potential Energy of Baroclinic Rossby Waves in the North Pacific
Publisher: American Meteorological Society
Abstract: Estimates of baroclinic Rossby wave potential energy spectra for various parts of the North Pacific were calculated from published material containing information about this energy in many different formats, definitions ...
Annual Baroclinic Rossby Waves in the Central North Pacific
Publisher: American Meteorological Society
Abstract: We analyze XBT data, collected in the central North Pacific under the NORPAX program (TRANSPAC), by means of inverse methods (cross-spectral fit). We separate the data into two parts: a fluctuation with length scales in ...
Interannual Baroclinic Rossby Waves in the Midlatitude North Atlantic
Publisher: American Meteorological Society
Abstract: Twenty-six year time sequences of upper thermocline temperature block-averaged in 5-degree latitude and longitude squares reveal strong, in-phase vertical coherence and low to moderate horizontal coherence over 550 km. ...
Rossby Wave-Induced Secondary Flows near Barriers, with Application to the Hawaiian Ridge
Publisher: American Meteorological Society
Abstract: We restudy the reflection of baroclinic Rossby waves from a nonzontal barrier. We add lateral friction to an earlier study by Mysak and Magaard to obtain a more realistic secondary flow near the barrier. Contrary to the ...
Rossby Wave Analysis of Subsurface Temperature Fluctuations along the Honolulu-San Francisco Great Circle
Publisher: American Meteorological Society
Abstract: Seven years of XBT observations collected between Honolulu and San Francisco reveal subsurface temperature fluctuations with strong, in-phase vertical coherence and fair horizontal coherence over 1000 km distance. Their ...
Rossby Wave Driven Eulerian Mean Flows Along Non-Zonal Barriers, with Application to the Hawaiian Ridge
Publisher: American Meteorological Society
Abstract: We show that the reflection of baroclinic Rossby waves from a non-zonal barrier generates a Eulerian mean flow along the barrier. In order to produce a mean current of realistic magnitude, friction (in the form of Rayleigh ...
Radiating Instability of Nonzonal Oceanic Shear Flows with Application to the Kuroshio Extension Current
Publisher: American Meteorological Society
Abstract: This paper proposes a mechanism to explain the fairly energetic internal temperature fluctuations observed in the regions far away from the axis of the Kuroshio Extension Current (KEC). Based upon the typical observed time ...
The North Hawaiian Ridge Current: A Comparison between an Analytical Theory and Some Prior Observations
Publisher: American Meteorological Society
Abstract: A previously developed analytic model of Rossby wave-induced mean current along lateral boundary is least-squares fitted to the geostrophic current derived from two closely sampled hydrographic sections windward (northeast) ...
On Stable and Unstable Rossby Waves in Non-Zonal Oceanic Shear Flow
Publisher: American Meteorological Society
Abstract: We derive linear equations for the study of baroclinic instability of a non-zonal oceanic shear flow whose direction is allowed to change with depth. These equations can be used to study unstable disturbances as well as ...
