Figure 1.9.
Typical horizontal flow fields (streak photographs) during an “amplitude vacillation” cycle of the rotating annulus in
the same system as in Figures 1.8-1.13. For color detail, please see color plate section.

Figure 1.10.
Results from numerical simulations of a baroclinic amplitude vacillation in a rotating annulus similar to that of
Hignett et al.
[1985] showing (a) azimuthal mean azimuthal flow at maximum wave amplitude, (b) azimuthal mean azimuthal
flow at minimum wave amplitude, and (c ) azimuthal mean temperature fields at minimum (solid) and maximum (dashed) wave
amplitude during the vacillation cycle.
