Session 3 Aerosol Deep Convection Interaction

Tuesday, 9 January 2018: 8:30 AM-10:00 AM
Room 12A (ACC) (Austin, Texas)
Host: 10th Symposium on Aerosol-Cloud-Climate Interactions
Adele L. Igel, Univ. of California, Davis, CA

Understanding the interactions between aerosol particles and deep convective clouds is challenging for a number of reasons. Aerosol particles influence the microphysical properties, latent heat release, and ultimately the dynamics of these storms. Characteristics of the anvils, hydrometeors, surface precipitation, and cold pools can be significantly altered as a result. Deep convective clouds are in turn important for removing and redistributing aerosol particles in the atmosphere. For this session, we seek presentations on interactions between aerosols and all types of isolated and organized deep convection in the tropics and midlatitudes, including mesoscale convective systems and hurricanes. Papers focusing on aspects of aerosol–deep convection interactions such as precipitation, cloud microphysical and radiative properties, cold pools, and storm dynamics are welcomed. Papers on deep convective transport of aerosols and dust are also strongly encouraged.
