Hi terstorm1012,.
these storms have developed between august and January, in particular between September-December; same months, latitudine and sea surface temperature that developed North Atlantic Tropical cyclone like Karl nov1980, Michael 0ct2000, Noel nov2001, Vince oct2005, Epsilon Dic2005, Grace oct2009, Chris junNov2012 ecc.
their development depends from thermodynamic imbalance between cold air and warm sea surface.
Extratropical ciclone + warm seclusion = tropical transizion in the cyclonic center=
subtropical storm ------> tropical cyclone obtained.
