Baroclinic instability of a meridionally varying basic state
… a resonant triplet of neutral waves can lead to baroclinic instability. It is also demonstrated that resonant interactions between a slightly supercritical unstable linear mode and two neutral waves can destabilise the weakly finite amplitude equilibration of the unstable mode that would occur in …

Moist Baroclinic Instability and Macroturbulence of the Midlatitude Atmosphere
… and challenge us to extend our theories of baroclinic instability and macroturbulence beyond dry adiabatic dynamics. Two specific phenomena in which latent heating plays a key role and that are poorly understood form the central focus of this thesis. Past research has identified a special …

Generation of mid-ocean eddies : the local baroclinic instability hypothesis
The plausibility of local baroclinic instability as a generation mechanism for midocean mesoscale eddies is examined with a two-layer, quasi-geostrophic (QG) model forced by an imposed, horizontally homogeneous, vertically sheared mean flow and dissipated through bottom Ekman friction, Explanations …

Linear normal mode analysis of baroclinic instability in a meridional channel
… the range of wavenumber and shear for which instability is possible is larger. Established cutoff criteria for the equal-layer zonal case are not applicable, and no analogous criteria has yet been found. Growing modes are found even for very weakly sheared flows, and this suggests that …

Inhomogeneous potential vorticity homogenization and equilibrium in simple models of baroclinic instability with implications for the extratropical circulation by Pablo Zurita-Gotor.
Baroclinic eddies are an important component of the General Circulation which regulate the extratropical climate by transporting heat and momentum. An idealization of this feedback is provided by baroclinic adjustment theories (Stone, 1978), which envision a linearly neutralized mean state. Based …

Nonlinear Solutions to a Two-Layer Quasi-Geostrophic Model of the Gulf Stream
… driven by an energy conversion process known as baroclinic instability and observations suggest that nonlinearity is an important part in this process. In order to understand the fundamental role of nonlinearity in baroclinic instability, an inviscid 2-layer quasi-geostrophic model is …

Mechanisms of Interactions between Aerosol Physics and Atmospheric Dynamics
… is attributed by low-frequency oscillations of baroclinic instability of the region. We proposed that the impacts of Saharan Air Layer (SAL) on large-scale climate dynamics mainly occur through coupling of dust radiative forcing with eddy energetics of the African easterly jet-African easterly …

The Effects of Diabatic Heating on Storm Track Dynamics
… adequate to capture shallow, short wavelength baroclinic waves. The model is forced by realistic orography and diabatic processes including radiative relaxation, surface heating and condensational heating. Time-mean analyses of the statistically equilibrated eddy ensemble includes time-mean …

Slope/shelf circulation and cross-slope/shelf transport out of a bay driven by eddies from the open ocean
… spontaneously generating eddies through baroclinic instability. A PV front forms in the first layer shoreward of the base of the topography due to the lower-layer eddy-slope interactions.
