- Stability of a second-order semi-implicit semi-Lagrangian (SISL) model
- On the Accuracy of Semi-Lagrangian Numerical Simulation of Internal Gravity Wave Motion in the Atmosphere
- Improved accuracy in conservative semi-Lagrangian transport in numerical models
- High-order conservative interpolation of geophysical data
- 3rd-Order temporal discretizations for semi-implicit semi-Lagrangian (SISL) models
- Emphasis on scalable finite volume (FV) methods: e.g. one-step explicit methods
- Development of high-order accurate, one-step FV methods using characteristics
- Extension to genuine multi-dimensionality using bicharacteristics
- Implementation of a 2-D x-z fully compressible non-hydrostatic model

- Neutral Atmospheric Convection (2.0 Mb) - This is the standard 2-D convecting bubble in a dry neutral atmosphere test case using a Godunov-type model with a second-order approximate Riemann solver based on a flux wave decomposition. 160 x 80 cells are used. The second-order fluxes are limited with a van Albada limiter. Multidimensionality is achieved via an alternating dimensional split.
- Density Current (1.4 Mb) - This is a density current (advancing front) test case with the same model as before except using 500 x 200 cells.
