Case Study

Rapid Cyclogenesis over Iceland

In this study a development of a mid-latitude cyclone will be shown. The development takes place because of the interaction between an upper level PV anomaly and a tightening/sharpening baroclinic zone, which can be identified as a low-level PV anomaly. Mutual interaction takes place which eventually leads to a deep surface cyclone. What makes this case special is the fact that the surface cyclone does not show much displacement, especially during the deepening phase. This could be linked to the effect of the orography in Iceland and the fact that the upper level trough is quasi-stationary.

In this investigation the development of this system will be closely observed on the basis of satellite imageries and the NWP-field. Moreover the results will be linked to two conceptual models, namely Rapid Cyclogenesis and Upper Level Low.
