摘要：

The lows in the eastern Mediterranean (EM) based on the 1982-86 ECMWF data were classified according to some indicative variables of the low center's surroundings including horizontal scale, temperature, static instability, humidity, surface latent heat flux, baroclinicity and the jetstream location. A quite distinct group of cold meso-alpha scale (1300 km) cyclones was identified and named the CS (cold small-scale) cyclones. These Mediterranean CS cyclones were found to be characterized by higher-than-average vorticity for cyclones with a similar scale, stronger sea latent heat fluxes but also slightly enhanced baroclinicity and near average low-tropospheric static instability.
