abstract = {In this study, we present an expansive sensitivity analysis
of physics configurations for cloud cover using the Weather
Forecasting and Research Model (WRF V3.7.1) on the European
domain. The experiments utilize the meteorological part of a
large ensemble framework known as the Ensemble for
Stochastic Integration of Atmospheric Simulations
(ESIAS-met). The experiments first seek the best
deterministic WRF physics configuration by simulating over
1,000 combinations of microphysics, cumulus
parameterization, planetary boundary layer physics (PBL),
surface layer physics, radiation scheme and land surface
models. The results on six different test days are compared
to CMSAF satellite images from EUMETSAT. We then selectively
conduct stochastic simulations to assess the best choice for
ensemble forecasts. The results indicate a high variability
in terms of physics and parameterization. The combination of
Goddard, WSM6, or CAM5.1 microphysics with MYNN3 or ACM2 PBL
exhibited the best performance in Europe. For probabilistic
simulations, the combination of WSM6 and SBU–YL
microphysics with MYNN2 and MYNN3 showed the best
performance, capturing the cloud fraction and its
percentiles with 32 ensemble members. This work also
demonstrates the capability and performance of ESIAS-met for
large ensemble simulations and sensitivity analysis.},
