Movies 1. Type B (non-reversing) Taylor vortex flow at ω=6.1 and Re_a=240 with wavenumber k^B=3.4. Angular momentum and azimuthal vorticity are shown in a meridional cross-section over a modulation period T. Red (blue) corresponds to positive (negative) values, showing r in [1,2] and z in [0,4π/k^B].	Movies 2. Type A (reversing) Taylor vortex flow at ω=1 and Re_a=240 with wavenumber k^A=3.0. Angular momentum and azimuthal vorticity are shown in a meridional cross-section over a modulation period T. Red (blue) corresponds to positive (negative) values, showing r in [1,2] and z in [0,4π/k^A].
