Vertical vorticity at selected pressure levels

The following plots show contours of vertical vorticity during the genesis and mature stage of the disturbances. Contour levels are: thick contours 10^-4 s^-1 s^-1; thin contours 2*10^-5 s^-1; Negative contours blue/dashed. Regions of cyclonic > 2*10^-5 s^-1 are shaded pink; regions of anticyclonic vorticity < -2*10^-5 s^-1 shaded light blue.
