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 1, we explored two new methods to nest LES in the HARMONIE model.
