Climatological analysis of Mediterranean cyclones using ECMWF data

P. Alpert, B. U. Neeman, Y. Shay-El

Research output: Contribution to journalArticlepeer-review


A thoroughly objective method for the definition, selection and tracing of Mediterranean region cyclones is presented. The method is applied to the ECMWF 1982-1987 analyzed datasets to show monthly cyclone frequences, cyclonic tracks and vertical variation of average relative vorticity. Day-to-night changes and vertical variation of cyclonic frequencies/vorticities indicate the importance of the sea thermal effect in the eastern Mediterranean. In the western Mediterranean and to a lesser extent in the Cyprus region, the lee cyclogenetic effect is very pronouced. Monthly cyclone tracks are presented and they clearly indicate the preferred routes of cyclonic movements. -Authors
