| Zusammenfassung |
| The 2-D version of the non-hydrostatic fully compressible model MOLOCH
developed at ISAC-CNR was used in idealized set-up to study the start-up
and finite amplitude evolution of symmetric instability. The unstable
basic state was designed by numerical integration of the equation
which defines saturated equivalent potential vorticity qe*.
We present the structure and growth rates of the linear modes
both for a supersaturated initial state ("super"-linear mode) and
for a saturated one ("pseudo"-linear mode) and the
modifications induced on the base state by their
finite amplitude evolution. |
