Understanding the life cycle of precipitating systems is important for better nowcasting of significant weather and for improving weather prediction models. Doppler and Polarimetric weather radars have the ability to look simultaneously into the microphysics and dynamics of precipitation systems. The goal of this project is to make use of these powerful tools to perform combined analysis of dynamics and microphysics of precipitation systems, in order to better understand storm development. By using data from multiple Doppler radars, the 3D wind field may be retrieved. Simultaneously the polarimetric capability of the radars allows the retrieval of microphysical processes. The interaction between these two fields is complex and not fully understood at the moment. This project aims at highlighting the processes through which precipitation systems evolve by revealing the interdependence between the storm dynamics and microphysics. In a final stage the gathered knowledge will be used in an effort to improve nowcasting of high impact weather.
