Impact of the non-hydrostatism and the new Semi-Lagrangian horizontal diffusion scheme on high-resolution forecast of bura using Aladin model

A case of severe bura (Adriatic bora) of 14th November 2004 represents a hard real case test for the non-hydrostatic dynamics of Aladin model. A stable and efficient non-linear horizontal diffusion, based on the control of the degree of interpolation needed for the Semi-Lagrangian advection scheme, has been implemented in ALADIN. Both have been used as well as other possible options to improve the forecast of severe bura on 1st and 3rd February 2007.
