My Research

Cloud Microphysics and the Superdroplet Model

I'm a PhD student investigating (warm-)cloud microphysics and its implementation in climate models. In particular, I'm finding out what we can learn from the Superdroplet Model (SDM; Shima et al. 2009, 2020) about rain formation in tropical shallow cumulus. My focus is on SDM's representativeness and computational efficiency in comparison with other microphysics schemes. Currently I'm developing an SDM called 'Cleo' and using it to model simplified scenarios that test its convergence properties (with increasing number of superdroplets for example) and computational cost.
