PPT-Does Aerosol Loading in a Convective Environment Influence Cirrus Anvil Properties?

Betsy Berry and Jay Mace University of Utah American Geophysical Union 2011 Fall Meeting More CCN more small droplets less collision delayed raindrop formation Smaller sizes are lofted higher where they freeze latent heat release leads to increased buoyancy and a stronger updraft. p.connolly@manchester.ac.uk Introduction: Convective invigoration describes a pathway by which aerosols modulate cloud evolution, precipitation and radiation (Rosenfeld et al. 2008).
