"Computer models are the key tools used to predict climate and weather conditions, and the changes associated with human activities. Many physical processes that influence Earth's climate and weather occur on spatial scales shorter than typical global climate model grid sizes, and these processes must be parameterized in large scale models, e.g., microphysics, convection, boundary layer processes, radiation, subgrid variability, and process interactions. These subgrid processes are collectively called fast physics. Fast Physics in Large Scale Atmospheric Models: Parameterization, Evaluation, and Observations focuses on development of these so-called fast physics parameterizations and evaluates them against observations which are essential to climate studies and model development, requiring integration from observations to theories to models."-- Provided by publisher.
