A time-spectral approach to numerical weather prediction [PDF]
Computer Physics Communications, 2018 Finite difference methods are traditionally used for modelling the time domain in numerical weather prediction (NWP). Time-spectral solution is an attractive alternative for reasons of accuracy and efficiency and because time step limitations associated with causal, CFL-like critera are avoided.
