We analyze thermal convection in a fluid layer confined between isothermal horizontal boundaries at which the tangential component of the fluid stress vanishes. The layer rotates about an oblique, nearly vertical axis. Using a model set of equations for w, the horizontal planform of the vertical velocity component, and psi, a stream function related to a large-scale vertical vorticity field, we describe the instabilities of convection rolls. We show how the usual Küppers-Lortz instability…

Pattern formation in diffusive-advective coupled map lattices.

A practical algorithm is described for classifying generic pattern evolutions and for measuring velocities of traveling waves in coupled map lattices when advection is incorporated, in addition to the usual diffusive term.

The instability of rolls in a nonrotating layer is compounded by the Kuppers{Lortz instability when rotation is introduced and the most notable feature of the numerical simulations in square periodic domains of moderate size is the strong preference for convection in a square planform.

Rotating convection in an anisotropic system.

It is shown how the underlying base flow breaks the isotropy, thereby affecting the linear growth rate of convection rolls in such a way as to stabilize spirals and targets.

Transition from laminar convection to thermal turbulence in a rotating fluid layer

The convective flow in an infinite horizontal fluid layer rotating rigidly about a normal axis is investigated for the special case of infinite Prandtl number and free boundary conditions. For
