- W4328006250 abstract "The governing equations in atmospheric and ocean computational fluid dynamics models are specific forms of Navier-Stokes equations. Due to the complexity of the model itself, it is difficult to find the optimal parallel solution method. By coupling the atmospheric-ocean numerical model and simulating the interaction between the atmospheric-ocean fluids, the accuracy and prediction ability of the prediction model can be improved, but a more complex numerical calculation is needed. Based on the newly developed Model for Prediction Across Scales atmosphere model (MPAS-atmosphere, MPAS-A) and NOAA/EMC WAVEWATCH III (NWW3) wave model, we use the C-Coupler2 coupler to realize the construction of the global atmosphere-wave coupling numerical forecasting model. Due to the urgent need for operational timeliness of forecast, the parallel performance of the operating system has been analyzed. The parallel I/O, compiling options, parallel partitioning, and other optimizations were tested after the system deployment on the Lenovo cluster of the National Marine Environmental Forecasting Center. After optimization, a well-balanced performance is obtained, and computing and I/O resources are reasonably utilized, thus laying a foundation for the real-time coupling forecasting operation system of global across scales high-resolution atmospheric and ocean wave model." @default.
