Baroclinic, or internal, tides play a significant role in mixing in the deep ocean and in shallow seas (Munk and Wunsch, 1998; Garrett, 2003). In a stratified ocean, when the vertically uniform horizo...
Baroclinic Tides: Theoretical Modeling and Observational Evidence
Baroclinic Tides Theoretical Modeling
2015/7/23
This is a timely book. Baroclinic tides have emerged at the forefront of research in physical oceanography as they might provide a link between large-scale circulation and small-scale mixing. This boo...
A Tabletop Demonstration of Atmospheric Dynamics:Baroclinic Instability
Tabletop Demonstration Atmospheric Dynamics Baroclinic Instability
2015/7/22
Here we study a fundamental instability mechanism of the atmosphere that affects us very directly in terms of mid-latitude winter weather. We provide a hands-on demonstration of this instability using...
Beltrami-like fields created by baroclinic effect in two-fluid plasmas
Beltrami-like fields two-fluid plasmas
2011/9/9
A theory of two-dimensional plasma evolution with Beltrami-like flow and field due to baroclinic effect has been presented. Particular solution of the nonlinear two-fluid equations is obtained. This s...
The baroclinic instability in the context of layered accretion. Self-sustained vortices and their magnetic stability in local compressible unstratified models of protoplanetary disks
baroclinic instability magnetic stability protoplanetary disks
2010/11/10
Context. Turbulence and angular momentum transport in accretion disks remain a topic of debate. With the realization that dead zones are robust features of protoplanetary disks, the search for hydrody...
Intercomparison of intense cyclogenesis events over the Mediterranean basin based on baroclinic and diabatic influences
intense cyclogenesis Mediterranean
2010/1/27
A large number of high impact cyclones all over the Mediterranean basin have been reported on the data base of the MEDEX project (http://medex.inm.uib.es). A numerical study on the impacts and interac...
Low-order models of wave interactions in the transition to baroclinic chaos
Low-order models wave interactions baroclinic chaos
2009/11/16
A hierarchy of low-order models, based on the quasi-geostrophic two-layer model, is used to investigate complex multi-mode flows. The different models were used to study distinct types of nonlinear in...
Nonlinear features of equatorial baroclinic Rossby waves detected in Topex altimeter observations
Nonlinear features equatorial baroclinic Rossby waves Topex altimeter observations
2009/11/16
Using a recently proposed technique for statistical analysis of non-gridded satellite altimeter data, regime of long equatorially-trapped baroclinic Rossby waves is studied. One-dimensional spatial an...
Lyapunov,Floquet,and singular vectors for baroclinic waves
Lyapunov Floquet singular vectors baroclinic waves
2009/11/12
The dynamics of the growth of linear disturbances to a chaotic basic state is analyzed in an asymptotic model of weakly nonlinear, baroclinic wave-mean interaction. In this model, an ordinary differen...
Baroclinic instability of a symmetric,rotating,stratified flow:a study of the nonlinear stabilisation mechanisms in the presence of viscosity

Nonlinear instability baroclinic atmosphere planetary scale disturbances
2009/11/11
In this paper we investigate the stability of zonal flow in a baroclinic atmosphere with respect to finite-amplitude planetary-scale disturbances by applying Arnold's method. Specifically, we examine ...

Experiments of baroclinic waves in a rotating, baroclinic annulus of fluid are presented for two gap widths. The apparatus is a differentially heated cylindrical gap, rotated around its vertical axis ...
Synchronization and chaos control in a periodically forced quasi-geostrophic two-layer model of baroclinic instability
Synchronization chaos control quasi-geostrophic two-layer model baroclinic instability
2009/11/9
Cyclic forcing on many timescales is believed to have a significant effect on various quasi-periodic, geophysical phenomena such as El Niño, the Quasi-Biennial Oscillation, and glacial cycles. ...
