How the meteorological spectral nudging impacts on aerosol radiation clouds interactions?
View through CrossRef
Abstract. Meteorological and chemical modelling at the regional scale involve nudging to remain consistent with large-scale meteorology and meteo-chemical coupling to properly consider the interactions between aerosols, clouds and radiations. Both types of process can change meteorology, but not for the same reasons and not necessarily in the same way. To assess the possible interactions between nudging and coupling, several simulations are carried out with the WRF-CHIMERE coupled model. By comparison with measurements, we show that the use of nudging significantly improves the model performances. We also show that coupling changes the results much less than nudging. Finally, we show that when nudging is used, it limits the variability in the results due to coupling.
