Abstract	A three-dimensional (3D) cloud model with detailed microphysics is used to study the role of aerosol particles (AP) on the ice phase processes and preci pitation formation in mixed phase clouds. The model couples the dynamics of the NCAR Clark-Hall cloud scale model (Clark and Hall, 1991) with the detailed scavengin g model (DESCAM) of Flossmann and Pruppacher (1988) and the ice ph ase module of Leroy et al. (2007). The microphysics follows the evolution of AP, drop, and ice crystal spectra each with 39 bins. Aerosol mass in drops an d ice crystals is also predicted. The first simulated case is a deep convective cloud with a large anvil, sampled during the CRYSTALFACE campaign on July 2002 18 th (Heymsfield et al., 2005). Our model ( DESCAM-3D) is able to simulate the cloud in good agreement with the measurements in 10 km. Conc erning the role of AP, the simulations clearly show that changes in AP concentration in the boundary layer affects s ignificantly the dynamical evolution of the cloud a nd thus have an impact on the microphysical characteristics of the cloud even at high altitudes. The second case is a medium convective case over the Cévennes’ foothills in fall 2004 (Cha pon et al., 2007). Once again, DESCAM-3D simulates a realistic cloud field with radar reflectivities, rain accumul ation and spectra in agreement with the radar and d is rometer observations. As precipitation formation proceeds v ia mixed phase processes, the impact of pollution i n terms of AP number on both the warm and on the cold processes i studied.
