Short summary
In mid-latitudes, the major fraction of precipitation is initiated via the ice phase. Cloud model simulations estimated the role of aerosol particle types and heterogeneous freezing modes on the ice phase. The results show that the formation of mixed-phase and ice clouds is promoted by the immersion freezing mode, broad drop size spectra containing small as well as large drops, insoluble particles composed by bacteria, feldspar, and illite, and temperatures below -25°C.
