HIRLAM_INM and ECMWF analyses: comparison of their behaviour in cyclones detection

Abstract

One of the specific objectives of the MEDEX Project is the carrying out of a dynamically oriented climatology of cyclones that produce high impact weather in the Mediterranean. With this purpose, two cyclone catalogues, respectively based on HIRLAM_INM and ECMWF operational objective analyses, have been obtained for the last years in the Meteorological Centre of the Balearic Islands of the INM, the former covering the West Mediterranean basin and the latter covering all throughout the Mediterranean. When comparing both cyclone databases in the common area of study some significant differences have been observed, mainly on some areas. In this work these differences are shown and studied and some possible causes are explored.
