In Meteorological simulations, as computational capacity grows, one typically invests in increased resolution, more ensemble runs, addition of PDEs governing new physical processes. This has a massive impact on the computational complexity. Indeed, a new problem arising in simulations is the power cost of the total ensemble runs. The next generation of dynamical cores will require considerable innovation for them to be viable. Adaptivity is crucial in the success of algorithms for geophysical multiscale problems. One of the novelties introduced in this talk is the idea of ‘model adaptivity’, the automatic switching between models of different complexity in real time as and when required.
