Abstract:

HARMONIE, a non-hydrostatic NWP model has a single column version which is used for testing and validation of physical parameterisations. Since January 2010, this single column model (SCM) has been run on a daily basis in the KNMI parameterisation testbed (KPT). In this testbed, the HARMONIE SCM is run with different options and the output is compared with a wide variety of observations and other participating SCMs as well as large-eddy simulations (LES) model output. The evaluation presented here makes use of the advanced observation site Cabauw in the Netherlands, with a focus on shallow convection, turbulence and cloud formation. The examples shown illustrate the potential of the daily monitoring and in-depth evaluation to detect and improve model deficiencies.
