This workshop was sponsored, in part, by the University of Louisville College of Arts and Sciences. We thank them for their support. |

The purpose of this workshop was to enhance our understanding of bow echoes with help from operational meteorologists, university personnel, and the research community. It was a very convenient opportunity to review recent research and learn new findings concerning bow echoes, and possibly expand this into future collaborative research with new contacts within and outside of the National Weather Service.
