It is shown to eliminate components with frequencies higher than a specified cut-off value. Thus it is valuable for integrations of the equations governing atmospheric flow. The scheme is implemented in a shallow water model with an Eulerian treatment of advection. It is compared to a reference model using the semi-implicit (SI) scheme. The LT scheme is shown to treat dynamically important Kelvin waves more accurately than the SI scheme. | Funding Details: | Irish Research Council for Science, Engineering and Technology | Type of material: | Journal Article | Publisher: | Wiley | Journal: | Quarterly Journal of the Royal Meteorological Society | Volume: | 137 | Issue: | 656 | Start page: | 792 | End page: | 799 | Copyright (published version): | 2011, Royal Meteorological Society | Keywords: | Numerical weather prediction; Time integration; Filtering | Subject LCSH: | Numerical weather forecasting Laplace transformation Filters (Mathematics) |
