Divergence:
There are two maxima in the satellite signal, the western one representing the Instant Occlusion, the eastern one the
frontal cloud. The isentropes show a typical unstable distribution in the area of the Instant Occlusion and a typical
downward inclined zone of high gradients, a frontal zone in the area of the frontal cloud band. There are also two maxima
of convergence corresponding to both features. All these configurations are very typical for this conceptual model.
PVA:
There is strong PVA at high layers, but as the vertical cross section is more NW-SE oriented, the PVA maximum is more in
the frontal cloud band than in the Occlusion. This deviates somewhat from the ideal case.
Vertical Motion (Omega):
The field of vertical motion shows a lot of upward motion: with the frontal cloud band and with the Instant Occlusion cloud
spiral. The latter shows upward motion more in the lower layers and some sinking above. Also this field corresponds to the
ideal form.
