Meteorological Physical Background
These two theories can be applied to explain the cyclogenesis event in this case study.
The Hoskins theory based on PV and PV anomalies
In this study in the beginning the first signs of the existence of a upper- PV anomaly could be seen in the WV 6.2 imagery.
It was also clear that this anomaly was interacting with a low-level baroclinic zone which was a former old
frontal zone. The process of mutual interaction eventually leaded to the development of a intense surface
cyclone.
Orographic lee cyclogenesis
The orography of Iceland might also have played a role in the typical stationary development.
The modelfields show the presence of a lee-trough at the southeastern side. It seems that the phase-locking
of the stationary deepening upper level trough and the lee-trough was favorable for a rapid development.
