The 5th International Workshop on Nonhydrostatic Models is relevant to all aspects of nonhydrostatic models ranging from Large Eddy Simulation models to nonhydrostatic global models, including dynamical frames, physics schemes, data assimilation schemes and regional climate models. The following topics are also welcome: predictability and applications to mesoscale phenomena, such as tropical cyclones, heavy precipitations, and shallow clouds. The future of high-performance computing for the meteorological and climate research is one of our great concerns.
