COSMO-7CFL & wind on level 33 Poster from Marie Müllner, Guy de Morsier The problem: • Tests of modified diffusion: • no changes at boundaries (new nl: hd_corr_bd_x) • possibility to have a different (small) diffusionin the inside of the domain with a smooth transition • do not diffuse pressure (new nl: hd_corr_in_p) Tuning the horizontal diffusion in the COSMO model Power spectra of the kinetic energy of COSMO-2 for different horizontal diffusion experiments wave length • COSMO-7 only u,v,w: 0.25 • COSMO-2 only u,v,w: 0.15 wave number
