ResumoClouds are important components of the climate system as they affect the Earth's albedo and they participate in the hydrological cycle. One of the largest uncertainties in climate modelling is related to the parameterization of convective processes and, in particular, the question of how anthropogenic emissions may affect the different types of clouds is still open. Most research has been devoted to warm stratocumulus clouds, and only recently some studies incoporate changes in cirrus and mixed phase clouds. Emissions of gases and particles during biomass burning may affect the microphysics and dynamics of clouds developingnear and downwind of said emissions, and some studies have suggested that precipitation may be inhibited. Nevertheless, there have not been many studies that explore the effect that cloud condensation nuclei (CCN) originated by biomass burning may have on deep convective clouds, in which the ice phase is dominant. In this study we have introduced changes in the parameterization of the autoconversion and accretion processes in the Advanced Regional Prediction System (ARPS, developed at the Center for the Analysis and Prediction of Storm at the University of Oklahoma). The CCN used in the model were obtained from literature, and correspond to experimental studies in the Amazonia/Rondonia regions of recent and aged particles. ARPS was run on thermodynamic conditions representative of Northern Argentina during November, hundreds of kilometers away form the CCN sources. The results suggest that when the atmospheric conditions are very unstable (leading to very deep convection, even in cases, to the occurrence of tornadoes), the autoconversion and accretion processes are not significant in changing the overall cloud dynamics, neither the total precipitation at the surface. These results indicate that the dynamics of the deep, mixed phase clouds simulated is not sensitive to the input of large concentrations of CCN originated during biomass burning. We are currently exploring the impact of introducing large concentrations of ice nuclei (IN), introducing changes in the parameterizations of the ice phase in ARPS.
