The Seminar presented a pedagogical review of recent advances and future challenges in high-resolution numerical modelling of the atmosphere and ocean. It was held at ECMWF from 2-5 September 2013.
Description
The presentations during this seminar gave a pedagogical review of recent advances and future challenges in high-resolution numerical modelling of the atmosphere and ocean. Historically, the development of numerical methods is driven by questions of numerical stability, accuracy and preserving physical conservation laws. However, recent developments are primarily driven by the efficiency of numerical methods on the massively parallel computer architectures expected in the future. Topics include a discussion of various approximations to the fully-compressible Euler equations, different horizontal and vertical discretizations, as well as different time integration schemes.
