Shear instability, the mechanistics of perturbation growth on plane parallel shear flow
Wave-mean flow interactions in midlatitudes, storm track dynamics, eddy life cycles. Possible dynamical regimes in midlatitude circulation.
Stratospheric dynamics: Planetary wave structure and variability. The effects of downward reflection on wave structure.
TMME- Tropical Modulation of Midlatitude Eddies - the effect of ENSO on midlatitude circulation.
Mid latitude eddy life cycle dynamics. The effects of basic state wave geometry on the life cycles (LC1 vs LC2), and possible consequences for larger scale circulation- storm track structure and variability, the response of midlatitudes to El Nino.
