Analysis and improvement of a semi-Lagrangian exponential scheme for the shallow-water equations on the rotating sphere

Autor: Steinstraesser, João Guilherme Caldas, Schreiber, Martin, Peixoto, Pedro da Silva

In this work, we study and extend a class of semi-Lagrangian exponential methods, which combine exponential time integration techniques, suitable for integrating stiff linear terms, with a semi-Lagrangian treatment of nonlinear advection terms. Parti

Report

Parallel-in-time integration of the shallow water equations on the rotating sphere using Parareal and MGRIT

Autor: Steinstraesser, João Guilherme Caldas, Peixoto, Pedro da Silva, Schreiber, Martin

Despite the growing interest in parallel-in-time methods as an approach to accelerate numerical simulations in atmospheric modelling, improving their stability and convergence remains a substantial challenge for their application to operational model
