Abstract
In the field of extreme weather and climate events management and territorial protection, there is an increasing need for decision support tools that allow the creation of the most realistic virtual scenarios in time for prevention and the design of risk containment systems. This paper describes the operation of an atmospheric simulator capable of generating weather field outputs within a limited domain and with very high resolution. The simulator is technically characterized by the use of a bottom-up approach that does not use differential equations; in fact, the atmosphere is modelled by means of SPH (Smoothed-Particle Hydrodynamics) fluids, while the different atmospheric phenomena (convection, turbulence, pressure distribution), are output by the software as emergent properties of the single interactions between the SPH particles of the simulated atmosphere. On a practical level, it can be initialized with data that are inhomogeneous in quality and distribution (Radar, Sensors, Historical Surveys and data from forecast models) and used by personnel who have only GIS skills.
