Dual-Doppler processing of weather radars for the analysis of storm dynamics in association with polarimetric analysis of microphysics.

了解降水系统的生命周期对于更好地近距离预报重大天气和改进天气预报模式非常重要。多普勒和偏振天气雷达能够同时观察降水系统的微物理和动力学。该项目的目标是利用这些强大的工具对降水系统的动力学和微观物理进行联合分析，以更好地了解风暴的发展。利用多部多普勒雷达的资料，可以反演三维风场。同时，雷达的偏振能力允许恢复微物理过程。这两个领域之间的相互作用是复杂的，目前还没有完全了解。该项目旨在通过揭示风暴动力学和微观物理之间的相互依存关系，突出降水系统的演变过程。在最后阶段，收集到的知识将用于改进对高影响天气的即时预报。

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.
