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
