1. Modelling in the Coquimbo Region Melitta Fiebig Wittmaack + Inge Bischoff-Gauss (IWR/FZK) + Orlando Astudillo

2. ¿What is KAMM? Karlsruhe Mesoscale Atmospheric Model ( Adrian and Fiedler.) non- hydrostatic complex topography (terrain following coordinate system) chemical module coupling, aerosol module coupling, etc.

3. Datos de entrada requeridos: + vertical soundings of wind, temperature and humidity Input:

4. Output: 3D distributions of Ywind Ytemperature Yhumidity Yconcentrations of chemical species

5. First step: the larger flow-field with coarse discretization (Kalthoff et al. 2002)  t < 2 sec,  x = 4.7 km H = 15 km

9. Second step: smaller simulation area with finer discretization and 1 nesting

10. a: Δx = 1461 m, Δy = 1788 m i: Δx = 730.5 m, Δy = 894 m

14. Third step: The influence of the Embalse Puclaro on the local climate; 3 nestings and finest discretization (with Inge Bischoff-Gauß, IWR)

15. Simulated potential temperature rel. humidity on a summer day
