This lecture series will review basic techniques to simulate cloud processes, such as formation and growth of cloud droplets, formation of rain through collision/coalescence. Lectures will start with simple approaches such a bulk condensation model, and will gradually introduce more comprehensive methodology, such as the super-droplet method. Lectures will also involve demonstration and practical exercises with a simple cloud-scale model based on nonoscillatory-forward-in-time differencing for fluid flows. As the main cloud modeling project, the students will simulate a (non-precipitating) moist thermal rising in a neutrally stratified environment.
