โœฆ Synopsis

We have developed a parallel implementation of a meteorological limited area model using a standard domain decomposition technique. Several communication strategies and message-passing libraries are compared. Results are presented for low, medium and high spatial resolutions. A good performance is obtained in the high resolution test case with an efficiency higher than 85% of the theoretical maximum.

## Abstract A limited area, sixโ€level, primitive equations numerical weather prediction model has been developed to provide improved 24โ€ to 36โ€hour forecasts for the Australian region. Important features of the model include semiโ€implicit time differencing, and a nesting procedure which enables bou
