Scientific paper

Using modal equations of the anelastic approximation of convection, solutions are computed for moderate Rayleigh numbers, a Prandtl number equal to one, a density stratification of ten. The vertical vorticity modes may carry a substantial part of the kinetic energy. Stationary three-mode solutions are obtained for a Rayleigh number four times critical. The stratification favors hexagonal planforms for which the vertical speed at the center is directed downward. At a Rayleigh number eight times critical, only time-dependent, periodic solutions exist, in which the vertical vorticity plays an essential role.
