A class of semi-implicit predictor-corrector schemes for the time integration of atmospheric models

摘要: In this paper a class of semi-implicit predictor-corrector time integration schemes is proposed. Linear stability analysis used to identify promising methods and these are applied the nonlinear system shallow water equations on an icosahedral grid. The model testbed for future development more complete atmospheric model. Experiments with standard test cases from literature show that investigated produce stable results relatively long time-steps while maintaining sufficient level accuracy. These facts suggest analysed could be useful construction complex based Euler equations.
