Isentropes
Two distinct features can be derived from studying the isentropes. The cold front with an unstable character of up to 600 hPa and further to the east (49N13E) the pronounced unstable stratification which has a maximum around 700 hPa

Temperature Advection
The cold front is characterised by CA which reaches up to 300 hPa Further east, around 49N13E, an area with warm air advection might slightly contribute to rising motions and an unstable stratification of the troposphere.

Convergence
Within the cold front around 600 hPa and also further east around 800 hPa some convergence is found.

Vertical Motion (Omega)
Most rising motion are found in the unstable region ahead of the front.
