A Conversation on Modelling TCs

An hour-long discussion between leading experts on the challenges of operational modelling (NWP) and forecasting tropical cyclones, with a focus on forecasting for the Southwest Indian Ocean.

The conversation begins with contributor introductions – from Rebecca Emerton (UoR/ECMWF), Julian Heming (Met Office), Nick Klingaman (NCAS/UoR) and Linus Magnusson (ECMWF) and then follows the topics shown below, with their approximate timing.
