An Introductory Study of Warm Rain Productivity in Convective Clouds Influenced by Regional Climate Change
Thermodynamic soundings from climate model runs performed over the past 30 years, and projected 30 years into the future, are used in conjunction with a 1D warm rain model to provide insight on how warm rain productivity may change in the “warm” part of convective clouds over the U.S. Regional variations of aerosol, assuming a constant fraction of such aerosol act as cloud condensation nuclei, are also considered. These results will be useful for future studies of mixed-phase convective clouds with more complex numerical models, to determine where and how the precipitation in such clouds over the U.S. might be more susceptible to changes in regional climate.
The present study was conducted as part of a new sophomore-level, research-oriented laboratory at Purdue University in the Atmospheric Science program.
