Typical Appearance In Vertical Cross Sections
- Isentropes are inclined, but less pronounced than for fronts; sometimes there is a double structure (frontal character at the surface and above)
- Often within weak WA
- Convergence in lower levels, sometimes in upper levels, but there are big differences from case to case
- Isotachs show a low level minimum at the transition between the Occlusion and Convergence Cloudiness
