Abstract. Mediterranean cyclones are extratropical cyclones, typically of smaller size and weaker intensity than other that develop over the main open ocean storm tracks. Nevertheless, can attain high intensities, even comparable to ones tropical thus cause large socioeconomic impacts in densely populated coasts region. After cyclogenesis takes place, a variety processes involved cyclone’s deve...

We present a set of equations governing the motion of a body due to prescribed shape changes in an inviscid, planar fluid with nonzero vorticity. The derived equations, when neglecting vorticity, reduce to the model developed in [4] for swimming in potential flow, and are also consistent with the models developed in [2,5,15] for a rigid body interacting dynamically with point vortices. The effe...

The drift of ions in a magnetized plasma or the height fluctuations of a rotating fluid layer are described by the conservation equation of a potential vorticity. This potential vorticity contains an intrinsic length scale, the hybrid Larmor radius in plasma, and the Rossby length in the quasigeostrophic flow. The influence of this scale in the evolution of a random initial vorticity field is i...
