Baroclinic Instability

Overview page. Subjects: Meteorology and Climatology.

One kind of instability that can occur in fluids in rotating systems, even though they are statically stable, is termed baroclinic instability. This kind of instability can arise when the...

Baroclinic instability on hot extrasolar planets

I. Polichtchouk and J. Y-K. Cho.

in Monthly Notices of the Royal Astronomical Society

August 2012; p ublished online August 2012 .

Journal Article. Subjects: Astronomy and Astrophysics. 12577 words.

Instabilities of Jets and Fronts and their Nonlinear Evolution

Vladimir Zeitlin.

in Geophysical Fluid Dynamics

February 2018; p ublished online April 2018 .

Chapter. Subjects: Physics. 21743 words.

Notions of linear and nonlinear hydrodynamic (in)stability are explained and criteria of instability of plane-parallel flows are presented. Instabilities of jets are investigated by direct...

Toroidal vortices and the conglomeration of dust into rings in protoplanetary discs

Pablo Lorén-Aguilar and Matthew R. Bate.

in Monthly Notices of the Royal Astronomical Society: Letters

P ublished online August 2015 .

Journal Article. Subjects: Astronomy and Astrophysics. 3899 words.

We identify a new hydrodynamical instability in protoplanetary discs that may arise due to variations in the dust-to-gas ratio and may lead to concentration of dust grains within a disc....

Rotating Shallow-Water Models with Moist Convection

Vladimir Zeitlin.

in Geophysical Fluid Dynamics

February 2018; p ublished online April 2018 .

Chapter. Subjects: Physics. 8081 words.

It is shown how the standard RSW can be ’augmented’ to include phase transitions of water. This chapter explains how to incorporate extra (convective) vertical fluxes in the model. By using...

A simple model for solar isorotational contours

Steven A. Balbus.

in Monthly Notices of the Royal Astronomical Society

June 2009; p ublished online May 2009 .
