This paper presents the first scientific application of local time-stepping (LTS) schemes in the Model for Prediction Across Scales-Ocean (MPAS-O). We use LTS schemes in a single-layer, global ocean model that predicts the storm surge around the eastern coast of the United States during Hurricane Sandy. The variable-resolution meshes used are of un...

... a result, when running with more than a few processes, there may not be enough interface cells in the mesh for an equal number to be spread across processes in a way that also respects the expense of MPI communication calls. To avoid this issue, additional interface layers are added to the mesh (see Figure 8). Because LTS3 is O (∆t) 3 everywhere on the mesh, these additional interface layers have no negative impact on the model's accuracy. ...
