4-points spline option for the semi-Lagrangian interpolation (February 2005) (Dynamics)

Wednesday 24 May 2006

This is documentation was written by Filip Vana in February 2005 about the new option for the semi-Lagrangian interpolation: 4-points spline. It is supposed to be more precise and accurate than the current default interpolation requiring almost the same CPU consumption. The only problem seems (...)

2000 - Realization of a simplified, differentiable and realistic physical parametrization for incremental four-dimensional variational data assimilation (Variational)

June 2000

A complete set of the simplified physical parametrizations has been developed for incremental 4D-Var assimilation system. It contains a simplified computation of radiative fluxes, vertical turbulent diffusion, orographic gravity waves, deep convection and stratiform precipitation fluxes. The (...)
