Advanced Numerical Methods for Numerical Weather Prediction (NWP).

摘要

The long-term goal of this research is to construct the Navy s next generation global numerical weather prediction (NWP) model using new numerical methods specifically for distributed-memory computers. To take full advantage of the new computer architectures, the spherical global domain must be partitioned into local sub-domains, or elements, which can then be solved independently on the multiple processors of these computers. The numerical methods used on these sub-domains must be not only local in nature but also high-order in accuracy and highly efficient. Thus the final objective of this project is to construct a new global NWP model which is as accurate as the current spectral model (NOGAPS) while much more efficient, thereby allowing for finer resolution forecasts.
