Description:
In this study the influence of the direct radiative effect of aerosols on atmospheric dynamics over Europe is simulated using the Hirlam Aladin Research for Mesoscale Operational Numerical Weather Prediction in Euromed (HARMONIE) numerical weather prediction (NWP) model. In recent years the direct radiative effect of aerosols has become more accepted as a physical mechanism that should be included in NWP models in order to improve the accuracy of weather forecasts. For example Mulcahy et al. (2014) show that considering the influence of aerosols in NWP results in an improved radiation budget. The main goal of this study is to quantify the influence of the direct radiative effect of aerosols on atmospheric dynamics over short time scales. NWP models often use climatological aerosol data to consider the direct radiative effect of aerosols. In this study, the influence of considering direct radiative effect of climatological and real time aerosol distributions on the simulated atmospheric state is compared. Moreover, the direct radiative effect of aerosols during Russian wildfires in summer 2010 is studied to evaluate the magnitude of the aerosol influence during this heavily polluted situation.
