RAL Seminar: Simulating Cloud-Aerosol Dynamics Using LES, DNS, and ML

Cloud–aerosol–turbulence interactions have been studied in the laboratory using convection cloud chambers, such as the Pi Chamber at Michigan Tech University, which generates a turbulent cloud through mixing driven by a moist, warm bottom and a moist, cold top. However, the Pi Chamber is too small to explore the influence of turbulence on droplet collision–coalescence, a key step in the transition from cloud to drizzle. As a result, the Large-Scale Aerosol–Cloud–Drizzle–Convection Chamber (ACDC2) project has been underway since 2021 to conceptualize a new cloud chamber for studying collision–coalescence. To design such a chamber, numerical simulations allow us to reproduce, interpret, and extend the experiments conducted in the cloud chamber. In this talk, I will introduce how these approaches are used to improve our understanding of the Pi Chamber experiments, how they are utilized in designing a new chamber, and the challenges associated with these approaches. Ongoing work to continue the ACDC2 project will also be introduced.
