Environmental Characteristics Associated with the Tropical Transition of Mediterranean Cyclones

Various weather-induced natural hazards in the Mediterranean region like heavy rainfall, floods, or windstorms are associated with Mediterranean cyclones (Lionello et al., 2006; Flaounas et al., 2022). These cyclones are extra-tropical cyclones (ETC) that have baroclinic origins, related to the deviation of the jet stream meanders over the Mediterranean Sea (Flocas, 2000; Fita et al., 2007; Flaounas et al., 2015). In some rare cases, some cyclones develop in their mature stage similar characteristics to tropical cyclones (TC): an axisymmetric deep warm core, generally with a windless center surrounded by strong winds (Fita et al., 2007; Tous et al., 2013). Those Mediterranean Tropical-Like Cyclones (MTLC), are particularly severe and can cause important damage (Akhtar et al., 2014,
