Boundary Sources of Potential Vorticity in Geophysical Circulations, which can be tapped by the circulation. We concentrate on the bottom source, and use a new isopycnal numerical model to examine it. The sloping bottom of the ocean produces a broad region of PV reservoir, and it promotes significant change in both the interior general circulation and the structure of western boundary currents.

Analytical Models for Vertical Collapse and Instability in Stably Stratified Flows,nstabilities in the Boussinesq equations at low Froude number as compared with the low Froude number limiting dynamics. This criterion is developed through an analytic study of elementary exact solutions of the Boussinesq equations at low Froude numbers and involves the relative magnitudes of the local vertical vorticity and horizontal strain.

Direct Numerical Simulation of Particle Motion in Relation to Structures in the Convective Boundary the effect of preferential concentration is quite small for Stokes numbers of relevance to most atmospheric situations. We have also performed simulations for fluid tracer particles. We find that even for fluid tracers the velocity statistics differ greatly from the Eulerian values, in particular close to the inversion base.

Spectral Eddy-Viscosity Based Les of Shear and Rotating Flows, GFD applications: we show in particular for free-shear and wall flows a universal behaviour of the mean velocity profile, which becomes linear with a local Rossby equal to —1 in certain anticyclonic regions. We explain this result by a nonlinear self reorientation of the absolute vorticity.

Specific problems include convection at very high Rayleigh numbers in the classical Rayleigh-Bünard configuration, the effects of planetary rotation, thermohaline convection in the oceans, the coupling of convection with solidification or meltin
