The presenter analyses the mesoscale synoptic situation of medicanes from the past decades. He focuses on similarities in NWP fields.
The Mediterranean area can be affected by particular cyclones characterized by an unusual life cycle. This life cycle can be divided into two distinct parts: in the initial part the subject has a warm core and an asymmetric structure, which are typical aspects of a tropical storm. In the second part, it evolves rather like a cyclone of middle latitudes, usually explained by the classical theories; its origin is either on the sea as on the desert. These entities generally include extreme events, such as intense convection, strong winds and coastal storm surges; consequently, they assume a significant importance in the diagnostic and forecasting. This lecture will explain the energy contributions and the thermodynamic processes involved in the entire evolution, also describing the various significant aspects making use of adapted diagnostic procedures.
