The authors would like to acknowledge highly valuable discussions about this work with David Williamson. We sincerely appreciated his interest and suggestions. We also wish to acknowledge Jon Petch’s contributions to the early development of the NCAR single-column model. We have benefited from conversations with David Randall, Tony DelGenio, and Minghua Zhang on the subject of single-column modeling. Ralph Milliff’s comments on an early version of the manuscript were also greatly appreciated. This work was partially supported by the Climate Change Prediction Program (CCPP), which is administered by the Office of Energy Research under the Office of Health and Environmental Research in the Department of Energy Environmental Sciences Division, and by the DOE ARM Program.
