Deep Convective Clouds and Chemistry

Deep Convective Clouds and Chemistry : Deep Convective Clouds and Chemistry Summary of the Scoping Paper

Slide2 : Deep Convection and Chemical Species O3, aerosols affect radiative forcing Pollutants rained out

Slide3 : Upper Troposphere Lower Stratosphere Ozone HOx BrOx ClOx HOx Ozone Volatile organic compounds produced destroyed

Slide4 : washout and rainout NO production from lightning Processes in deep convection that affect chemical species Phase of cloud particles cloud microphysics and chemical species

Previous Studies : Previous Studies Comprehensive cloud and lightning with a fair amount of chemistry information STERAO, EULINOX, ELCHEM, TROCCINOX, SCOUT (Darwin, 12/2005) Comprehensive chemistry with little cloud and lightning information INTEX, TRACE-P, TTL-CHEM (Guam 1/2007)

Goals of DC3 : Goals of DC3 Quantify the role of deep convection as a source strength for radical species, their precursors, and nitrogen oxides in the midlatitude upper troposphere and lower stratosphere Determine the contribution of in-cloud physical and chemical transformations which affect UTLS chemistry

Slide7 : Determine fluxes of HOx, VOCs, NOx, NOy in and out of convection Lightning characteristics and L-NOx Cloud physics and chemical composition Dynamics and Turbulence Model – Observation Comparisons Impact of different types and locations of convection on UTLS composition and chemistry
