This research was motivated by observations collected in the Sierra Rotors Project and the Terrain-Induced Rotor Experiment (T-REX), for which the primary sponsor was the National Science Foundation (NSF). The first author acknowledges support of NSF through Grant ATM–0524891 to DRI, and of NCAR through the Advanced Study Faculty Fellowship. The second author was supported by the Croatian Ministry of Science through Grant 004-1193086-3036 to the Croatian Meteorological and Hydrological Service.
