| Abstract: |
We present a new model for studying penetrative convection in the anelastic approximation. This model is then applied to 2D numerical simulations of a convective region bounded below by a stable (radiative) region. Descending plumes excite strong gravity waves in the radiative region, with wavelengths given by the Brunt-Vaisala frequency. We present here two models with very different values of the ``stiffness'' parameter, S (a measure of the subadiabaticity to the superadiabaticity), so that we can get a qualitative understanding as to how this parameter affects the penetration. |
