In mid-latitudes, synoptic-scale anomalies appear in the upper troposphere and evolve along the jet streams. These upper-tropospheric anomalies are usually strongly stretched due to the action of the deformation field of the jet along which they evolve leading to a loss of (...)

The dynamics of some frequently-observed sudden growths of East-Atlantic extratropical cyclones are still an open issue. Using highly idealized models, some dynamical aspects that need to be better understood are explored. The study aims at shedding some light on the (...)
