This project aims to take advantage of the opportunity to buy out the dual polarization radar in a very low price based in the already paid leasing to develop research in nowcasting of severe thunderstorms based on knowledge acquired about the physical properties of clouds in the CHUVA thematic project. The basis of this research is the dual polarization radar operating in Campinas, for 24 months (two wet seasons) to capture intense events that provide the base for the study of the physical processes inside of thunderstorms aiming at improving predictability in the short term and the detection of severity. This project will install hail pads to create a database to provide information not only on the occurrence of hail, but also its size. In addition to the various studies components, as precipitation estimation using radar and satellite, electrification, cloud propagation, time rate of the volume of some hidrometeoros, cloud top growing rates and microphysical processes, this study aims to develop the SIGMA-SOS. The SIGMA SOS is a geographic information system that integrates the measured data as well as short-term forecasts and warnings. The Brazil bought several dual pol radars and is still expanding its network of radars to monitor extreme events. However, there is a lack of knowledge about the microphysical process and the interaction of dual pol radar with the hydrometeor inside the clouds, and this project intend to contribute improving this knowledge and forming students in this area. The interface with agriculture open a new perspective of applications in an important subject in Brazil. (AU)
