简介：The concept of dynamical downscaling, which makes use of large-sale constraining, is easily extended to global atmospheric models – as was suggested by Yoshimura and Kanamitsu in 2008. In this way, global large-scale re-analyses may be completed with consistent regional detail. We have prepared a 6-decade downscaling of NCEP-reanalysis, and shown its validity (Schubert-Frisius et al., 2017).The downscaling using regional and global models turns out to be of similar quality, if the spatial resolution is comparable. An additional added value of the global set-up is that consistent and homogeneous re-analyses can be constructed also for areas with little or even no regional data (von Storch et al., 2017).
