This presentation will focus on airborne lidar and in-situ microphysical data in and around tropical storms over the Atlantic Ocean. Prior analysis showed an enhancement of both large and small particles in the anvil outflow region of storms impacted by the SAL, but the enhancement didn’t extend more than 20 km from the cloud edges at a fixed altitude. For this work, aircraft lidar data will be used to study the vertical structure of aerosol layers near storms. Specifically, we will examine at what levels dust is preferentially redistributed, as well as the relative roles of sedimentation/evaporation of ice crystals in the anvil region and of detrainment at all levels. Ultimately, these data will be combined with satellite data and modeling studies to assess storm impacts on the vertical structure of dust across the Atlantic Ocean.
