Large Eddy Simulations of Trade-Wind Cumuli using Particle-Based Microphysics with Monte-Carlo Coalescence

A series of simulations employing the Super-Droplet Method (SDM) for representing aerosol, cloud and rain microphysics in LES will be discussed. SDM is a particle-based and probabilistic approach in which a Monte-Carlo type algorithm is used for solving the particle collisions and coalescence process. The model set-up used in the study is based on observations from the Rain In Cumulus over the Ocean (RICO) field project. Cloud and rain droplet size spectrum features obtained in the simulations are compared with previously published aircraft observations carried out during the RICO field project.
