4. Tuning the horizontal diffusion in the COSMO model
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) diffusion in the inside of the domain with a smooth transition
do not diffuse pressure (new nl: hd_corr_in_p)
COSMO-7 CFL & wind on level 33
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
