Atmospheric mineral dust particles – very efficient ice nuclei, are important heterogeneous cloud glaciation agents effective even far from their desert sources. A new generation of ice nucleation parameterizations, includes dust as ice nuclei. Based on these approaches, we have developed a regional dust-atmospheric modelling system to predict in real-time dust-induced ice nucleation. Satellite and ground-based cloud-ice-related measurements have been used to validate the model results. The predicted ice nuclei concentration if used as input in cloud microphysics of atmospheric models could further improve numerical weather prediction of cloud formation and associated precipitation.
