Relative Humidity:
The humidity is high ahead of the frontal zone, as it should be for an Ana Front. There is also humid air behind the frontal zone in the boundary layer, as the front is moving over warm sea.
Temperature Advection:
There is warm advection above of the frontal zone, as in theory. In this case, however, the middle and lower layers are within strong cold advection throughout the area of the cross section. This might be due to a very strong and rapid cyclone development, which is taking place.
Divergence:
There is convergence within the frontal zone and divergence above it, like in the theoretical distribution. Some weak areas of divergence and convergence are also present behind the frontal zone.
PVA:
The frontal zone is within positive vorticity advection, with the maximum near the tropopause, just as it is supposed to be.
Vertical Motion (Omega):
There is some ascending motion on the leading edge of the frontal zone, and descent behind it. Vertical motions are not very strong yet, because the front is young, as is typical for Ana Fronts.
