Title:Splitting methods for problems with different timescales.
Publication:Mon. Wea. Rev., 122, 2614-2622
Abstract:The time step for the leapfrog scheme for a symmetric hyperbolic system with multiple timescales is limited by the Courant-Friedrichs-Lewy condition based on the fastest speed present. However, in many physical cases, most of the energy is in the slowest wave, and for this wave the use of the above time step implies that the time truncation error is much smaller thatn the spatial truncation error.

Title:A comparison of the accuracy of three anelastic systems and the pseudo-incompressible system
Publication:J. Atmos. Sci., 51, 3549-3565
Abstract:The accuracy of three anelastic systems (Ogura and Phillips; Wilhelmson and Ogura; Lipps and Hemler) and the pseudo-incompressible system is investigated for small-amplitude and finite-amplitude disturbances. Based on analytic solutions to the linearized, hydrostatic mountain wave problem, the accuracy of the Lipps and Hemler and pseudo-incompressible systems is distinctly superior to that of the other two systems.

Title:Formulation of a lateral sponge layer for limited-area shallow-water models and an extension for the vertically stratified case
Publication:Mon. Wea. Rev., 123, 1542-1559
Abstract:A lateral sponge layer is designed to minimize the spurious reflections of nondispersive surface gravity waves in a linear, one-dimensional shallow-water limited-area model. The formulation selectively damps out the characteristic variables associated with the reflected waves inside the sponge layer.

Abstract:The orography representation in spectral models has always led to problems. These problems become critical in high-resolution models, like the variable-resolution spectral model used at Meteo-France, because they interact with the physical fields. The author describes a variational process to compute a spectral approximation of a gridpoint field.

Publication:Mon. Wea. Rev., 123, 1888-1903
Abstract:A nondivergent barotropic model and a shallow-water model are presented that exploit a high-order shape-preserving scheme for the advection of vorticity or potential vorticity as well as tracers. The dissipation associated with the advection scheme is found to be due to the spreading of features as they are advected across a finite-resolution grid.

Title:The pressure-advection term and additive splitting in split-explicit models
Publication:Q. J. Roy. Meteor. Soc., 121, 953-957
Abstract:In this note two major points are made. First, pressure advection needs to be carried within the adjustment step of split schemes if conservation of energy in the transformation between kinetic and potential energy is to be made possible. Second, in contrast to several recently published views, additive split schemes, without incremental addition of the advection contributions, are not necessarily noisy, given that the presented scheme is not.

Abstract:Comparative experiments of moist convection using hydrostatic and non-hydrostatic models are performed to study the suitability of the hydrostatic approximation for a high-resolution model when the grid size falls below 20km. The moist convection in the models is treated by the use of an explicit warm-rain process predicting cloud water and rainwater as well as by a semi-explicit scheme consisting of the warm-rain process and moist convective adjustment.
