Carlo Cafaro is a PhD student at University of Reading (United Kingdom), as a member of the Mathematics of Planet Earth Centre for Doctoral Training. His main research interests are ensemble forecasting of high-impact weather, in particular convection, verification of convective-scale probabilistic forecasts and communication of uncertainty in probabilistic weather forecasts.
The work presented at EGU 2018 corresponds to the research performed at UK Met Office as part of the Met Office Training and Research Summer School in 2017, within the Convection group in the Atmospheric Processes and Parametrization group.
The main scope of the project was to understand, by performing numerical simulations in an idealised framework, the dynamics of collision of two asymmetric density currents. When happening in real atmosphere (e.g. sea breeze convergence) this could lead to deep convection. Here a theoretical predictive model for the angle at the interface of the two fluids is proposed. This will aid the future parametrization of these processes in large-scale models which are unable to resolve the details of such flows.
