Effect of Deep Convection on Reactive, Soluble Chemical Species:  Relative Importance of Cloud Chemistry

Dr. Mary Barth, NCAR MMM/ACD

Deep convection can affect atmospheric chemical constituents in many ways.  Chemical species can be transported from the boundary layer to the upper troposphere, scavenged by precipitation, transformed by cloud chemistry, and affected by the modified UV radiation field.  Lightning associated with deep convection is a source of nitrogen oxides. In this presentation, I will discuss the importance of cloud chemistry relative to the scavenging and transport of species in deep convection by using a 3-dimensional convective cloud model to simulate the July 10, 1996 Stratospheric-Tropospheric Experiment: Radiation, Aerosols, and Ozone (STERAO) Deep Convection storm.
