Highly modular, single source code with plug-compatible modules Transportable and efficient in a massively parallel computing environment. Design priority for high-resolution (nonhydrostatic) applications Advanced data assimilation systems developed in tandem with the model itself. Numerous physics options, tapping into the experience of the full modeling community. Maintained and supported as a community mesoscale model to facilitate broad use in the research community. Research advances will have a direct path to operations. WRF Model Characteristics
