SUMMARY:PhDTalks | Uncertainty quantification and spatial biases assessment in precipitation forecasts: a methodology for real-time flood forecasting applications
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 18 marzo nell’aula Fassò (Edificio 4A)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLo speaker Enrico Gambini condurrà un seminario dal titolo “Uncertainty quantification and spatial biases assessment in precipitation forecasts: a methodology for real-time flood forecasting applications”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract\nAccurate meteorological forecasts are essential for mitigating flood impacts\, but uncertainty in convective precipitation positioning may significantly undermine flow predictions in small watersheds. A methodology is proposed to assess spatial biases in convection‐permitting model rainfall forecasts\, the procedure identifies preferential misplacement directions made by the meteorological model and incorporates this uncertainty into hydrological predictions. The approach was conducted on 64 significant convective rainfall events in the “hydraulic node of Milan” (Northern Italy) during 2013–2022. Quantitative precipitation forecasts from the MOLOCH (ISAC-CNR) meteorological model were compared with observed rainfall fields. Displacement errors were quantified using pattern matching\, revealing a consistent northeast bias. Kernel Density Estimation was then used to derive a bidimensional displacement probability density function\, this enables probabilistic forecast generation to quantify rainfall misplacement uncertainty effects on hydrological forecast. \nSpeaker’s bio \n\nEnrico holds a M.Sc in Environmental and Land Planning Engineering\, obtained at Politecnico di Milano in 2021. He is currently a PhD candidate (37-th cycle) in Environmental and Infrastructure Engineering\, in his PhD he is collaborating with the civil protection of Lombardy Region (CFMR) doing research on the enhancement of regional flood early warning system. His research is mainly focused on the use of machine learning algorithms for flood forecasting\, nowcasting and flood warning applications\, as well as uncertainty quantification of meteorological predictions. \nIn his spare time\, he enjoys playing chess (with poor results)\, hiking\, climbing and skiing.
