Soil moisture-precipitation feedback experiments over the Netherlands with AROME

This report is a contribution to the Knowledge for Climate Research Programme (KvK) under Theme 6. We have applied the climate version, HCLIM, of the meso-scale modelling system HARMONIE to study soil moisture–precipitation feedback mechanisms over the Netherlands. The studied time period, May 10–15 1999, represents a consecutive number of days with afternoon rain showers. By perturbing the soil moisture in a number of model experiments we have related changes in simulated precipitation to changes in simulated evapotranspiration. The resulting evaporation to precipitation ratio is comparable to another study for the same region but it is also shown that the results are sensitive for the size and location of the chosen area.
