Research institutions along the Front Range of Colorado have a long, rich history of advancing tropical cyclone research and applications. Despite the proximity, researchers across these multiple Colorado institutions found that they often only interacted at professional meetings. To address this issue, researchers started an informal workshop back in January 2008 between students, postdoctoral fellows, research scientists, and faculty from
Over the years, this workshop has allowed Colorado researchers to present innovative ideas and receive feedback thanks to longer speaking slots than at most meetings and multiple breaks to spur discussion. Today, the workshop, now called Front Range Tropical Cyclone Workshop, continues this tradition, and convenes a one-day, annual meeting. Workshop hosting alternates between Colorado State University in Fort Collins and the National Center for Atmospheric Research in Boulder.
