Adaptive multilevel modeling of land-atmosphere interactions

Adaptive multilevel methods allow full coupling of atmospheric and land surface hydrological models by preserving consistency between the large-scale (atmospheric) and the regional (land) components. The first case study consisted of coupling two simple models. One model provided the potential and the other the rotational components of atmospheric wind fields. In the second case study, intermittent coupling (every 4 hours) of three versions of the orographic precipitation model operating at 40-m, 60-m, and 80-km resolution, respectively, was established to replicate the precipitation patterns of specifically chosen storms. The third case study consisted of coupling the orographic precipitation model (40-km resolution) to a 1D model describing mass and energy balance conditions at the land surface. -from Author
