Isotachs (wind speed)
In the field of isotachs the situation is simillar like 6 hours before.
Vorticity Advection
Two maxima of PVA at approximately 300 hPa are clearly visible - one over Poland, and the other over Austria.
Omega
Through whole area the vertical motion, especially upward, can be seen with maximum at 700 hPa.
Potential Vorticity
The values of the PV=1 still sinks below 400 hPa in the rear side of the frontal zone.
Temperature Advection
Behind the frontal zone the cold advection becomes more significant and along the frontal cloud band warm advection is still present.
