Divergence:
Isentrops do show only a very weak frontal feature like a weak isentropic trough typical for an occlusion. This is in accordance with this special case study which shows a cloud system that is a medium-scale cloud spiral but it is different from the classical Coldfront type which usually is involved in the conceptual model of a Front Intensification by Jet Crossing
The field of divergence shows distinct convergence from low to middle levels especially in the area of the front intensification. This is in full agreement with the ideal configuration.
PVA:
The PVA cross section shows a distinct maximum over the area of the front intensification which is nearly a necessary condition for this conceptual model. But in this special case there is also a secondary maximum at low levels. This is - as already mentioned for the isentrops - a deviation from the typical cold front case and is in accordance with the medium-scale cloud spiral and a surface low connected to it.
Isotachs:
The distribution of isotachs does not fit into the expected form in an ideal case. But a comparison with the computed vertical cross section line shows that it is not in the area of the jet streak but more to the north where wind speed is much lower.
