Topic: Convective-Scale Data Assimilation II

Friday, June 07, 2024 from 15-17h UTC

Organizers and Conveners: Maud Martet (Météo-France, France), Prashant Kumar (Space Applications Centre, ISRO, India), Nora Schenk (DWD, Germany)

Delve into the dynamic world of Convective Scale Data Assimilation, a pivotal area shaping the precision and effectiveness of regional weather forecasting. This session zeroes in on the challenges and innovations at the convective scale, where the fusion of fine-scale data and advanced assimilation techniques holds the key to unraveling complex highly non-linear weather phenomena. We'll explore how enhancing data assimilation at this scale can lead to significant improvements in predicting localized, high-impact weather events. Submit your abstracts and contribute to a dialogue that seeks to push the boundaries of meteorological understanding and forecasting accuracy at the convective scale.
