Abstract: The impact of convection on the humidity and clouds in the tropical tropopause layer (TTL) during boreal summer 2007 is investigated in simulations of detailed cloud microphysical processes and their effects on the water vapor (H2O) profile along backward trajectories from the 379 K potential temperature (100-hPa pressure) surface. Convective influence is determined by tracing the trajectories through time-dependent fields of satellite-based convective cloud top height. The simulated H2O mixi...
