The intensity of sea surface heat fluxes, enhanced by the contrast between cold air and a relatively warmer sea surface, is very important for the intensification and maintenance of TLCs. Therefore, differently from tropical latitude hurricanes, cold air aloft is required in order to enhance thermodynamic disequilibrium and trigger the formation of Mediterranean TLCs [20]. Lower and upper level potential vorticity anomalies associated with TLCs have been identified and characterized by [PERSON] et al. [11] as dry PV, associated with the intrusion of dry stratospheric air, and wet PV generated by latent heat release due to condensation. Such latent heat release at low levels would extend to upper levels only in case of long lasting Medicanes. Therefore, previous studies (e.g. [2; 21; 22]) have shown that the vertical extension of the warm core varies from the lower to the upper troposphere and is linked to duration of the TLC phase (as also evidenced by [PERSON] [18]). Medicanes are generally considered as quite rare events. Recently, for the first time, [PERSON] et al. [23], exploiting high-resolution dynamical downscaling of atmospheric fields obtained from the NCEP/NCAR reanalysis, found systematic and homogeneous statistics of Medicanes, over a six-decades period. Their study estimated an average number of about 1.5 Medicanes per year. The advancements in satellite imagery, along with a comprehensive exploitation of all the available observations, have favored the clear identification of such peculiar events.As highlighted by [PERSON] et al. [10], since extratropical and tropical-like cyclone characteristics can alternate or even coexist in the same cyclonic system, satellite data and numerical modeling can be very useful to identify and characterize the development and mature phases of these systems. In this study we benefit from the unprecedented availability of microwave (MW) satellite observations in the NASA/JAXA Global Precipitation Measurement (GPM) mission era [24; 25] to characterize and monitor the different development phases of a meteorological event, named Numa by the Free University of Berlin's Meteorological Institute, that occurred in November 2017 in Southern Italy. The GPM international satellite mission was specifically conceived to unify and advance precipitation measurements from research and operational MW sensors for delivering next-generationglobal precipitation data products. The GPM constellation consists of a variable and continuously updating number of Low Earth Orbit (LEO) satellites equipped with conical and cross-track scanning radiometers. The main satellite of the constellation, the GPM Core Observatory (GPM-CO), a joint effort by NASA and JAXA, carries an advanced combined active/passive sensor package--the GPM Microwave Imager (GMI), acting also as a calibrator for the other MW constellation radiometers, and the Dual-frequency Precipitation Radar (DPR). The GPM-CO is currently considered the reference satellite-borne platform for the quantitative estimation of precipitation and precipitation microphysics characterization from space. The combined active/passive MW sensor measurements are used to derive consistent precipitation estimates from a constellation of satellites carrying MW radiometers provided by a consortium of international partners. The GPM constellation of satellites currently ensures 1-hourly coverage (on average) over the Mediterranean area. [PERSON] et al. (2016) illustrated the potential of the GPM constellation for monitoring heavy precipitation events in the Mediterranean region. In their work, the authors also showed the improved capabilities of the GMI with respect to other radiometers to depict the rainband structure of Medicare Qendresa, which occurred on 7-8 November 2014. The study focused on the use of GPM MW radiometers for surface precipitation monitoring, but no DPR overpasses were available for that case. In another study, [PERSON] et al.
