This page is based on a paper by J. L. Arreola, V. Homar, R. Romero, C. Ramis and S. Alonso from the Plinius Conference on Mediterranean storms held at Mallorca, Spain, October 2002.

From the NCEP meteorological analysis on 11 November at 00:00 UTC (time of maximum intensity of the cyclone), we can see an upper-level deep cold trough with two centers which rotated about each other during the event. They advected a high amount of vorticity over the Mediterranean. At low levels warm advection northeast of the surface low was very strong. The pressure gradient over eastern Spain and the Balearic Islands was very high, inducing very strong winds.
