Fast Processes in Large-Scale Atmospheric Models : Progress, Challenges, and Opportunities

Improving weather and climate prediction with better representation of fast processes in atmospheric models Many atmospheric processes that influence Earth’s weather and climate occur at spatiotemporal scales that are too small to be resolved in large scale models. They must be parameterized, which means approximately representing them by variables that can be resolved by model grids. Fast Processes in Large-Scale Atmospheric Models: Progress, Challenges and Opportunities explores ways to better investigate and represent multiple parameterized processes in models and thus improve their ability to make accurate climate and weather predictions. Volume highlights include: Historical development of the parameterization of fast processes in numerical modelsDifferent types of major sub-grid processes and their parameterizationsEfforts to unify the treatment of individual processes and their interactionsTop-down versus bottom-up approaches across multiple scalesMeasurement techniques, observational studies, and frameworks for model evaluationEmerging challenges, new opportunities, and future research directions The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.
