moisture profiles and idealized topography, such as a two-dimensional ridge or an isolated hill. Observation-based studies of realistic synoptic flow past complex terrain are still rare. This study is inspired by observations obtained during the Terrain-induced Rotor Experiment (T-REX; Grubišić et al. 2008 ). Our primary objective is to examine the impact of moisture on mountain waves associated with the interaction between westerly or southwesterly moist airflow and the Sierra Mountains. T-REX took

of atmospheric rotors was considerably advanced during the 1950s Sierra Wave Project in Owens Valley, California, in the lee of the southern Sierra Nevada ( Holmboe and Klieforth 1957 ). While primarily designed as a study of the mountain lee-wave phenomenon, data on atmospheric rotors were collected as well because the primary instrumentation in both phases of this project were instrumented sailplanes ( Grubišić and Lewis 2004 ). A number of important observations relating to the mountain wave

), aerosol and Doppler lidars, sonic and profile measurements from three 30-m and several smaller flux towers, and standard meteorological observations from an array of surface stations. Most systems were located along two valley transects just south of Independence. In this study, the southernmost wind profiler/RASS system and the 1.5-hourly radiosonde ascents from Independence airport are used to document the evolution of the valley flow, and flux data from the three 30-m Integrated Surface Flux
