Temperature Advection:
The isentropes of this rather large extended vertical cross section show a very unstable situation. There is a steeply downward inclined Cold Front zone and very unstable areas in front of it.
The TA field shows the approach of cold air together with the Cold Front where there is a maximum of CA and rather smooth WA in the warm sector in front of the Cold Front. This is not very spectacular but it agrees with the main featues of this conceptual model. But what is important is the fact that there is cold air protruding at middle levels from the Cold Front into the warm air of the warm sector. This is a typical event and leads to increasing instability.
Divergence:
Convergence is not as distinct as expected in an ideal case. There is only strong convection in low layers of the Cold Frontal zone and distinct divergence above. There is very weak convergence in the area of the Cbs developing in the warm sector. Whilst these configurations are not competely representative of the ideal configuration, they do show some aspects of the ideal case.
