Dynamical Meteorology and Climatology Unit

Francesco Ragone

Biography

I am assistant professor at the Earth and Life Institute at the Université Catholique de Louvain (UCLouvain) and senior researcher at the Royal Meteorological Institute of Belgium (RMI).

I obtained a PhD in Natural Sciences (Meteorology) at the University of Hamburg in 2013, and I have worked as post-doctoral researcher at the University of Hamburg (Germany), the University of Milan-Bicocca (Italy) and the Ecole Normale Superieure de Lyon (France). Since 2020 I hold a FED-tWIN joint academic position at UCLouvain and RMI, on modelling and forecasting of the climate system at seasonal to decadal scales using state-of-the-art models and tools from non-linear science.

Research interests

My research interests focus on the application to climate science of techniques from statistical mechanics, dynamical systems theory and data science. I have worked on development and application of techniques for analysis and simulation of extreme events,  linear response theory, non-equilibrium thermodynamics of atmosphere and climate, geophysical fluid dynamics, and stochastic parameterisations for climate models. My main area of research currently concerns the statistics of extreme events and the use of rare event algorithms to study climate extremes in complex numerical climate models.
