High resolution atmospheric modelling for mountain and valley stations and its applications to complex dispersion conditions

摘要

High resolution modelling with resolutions lower than 1 km is needed when complex topography is involved. Two case studies have been carried out at a valley and a mountain station with MM5V3.7 to evaluate three important topics: the influence of different boundary layer and soil schemes on the results, influences of the orographic shadowing option and the influence of using SRTM 3" satellite topographic data instead of the GTOPO 30" data used by default in MM5.
