KNMI Technical report - Downscaling HARMONIE-AROME with Large-Eddy Simulation

In this report we build on previous work by e.g. Neggers et al. (2012); Schalkwijk et al. (2015a); Heinze et al. (2017a) by directly downscaling a mesoscale model with LES, thereby bypassing the “grey zone” altogether. In the Dutch Offshore Wind Atlas (DOWA) project, we explored two new methods to nest LES in the HARMONIE model.
