This project will develop cloud droplet probes and phase-Doppler anemometry for measuring sizesegregated droplet concentrations at high wind speeds in the ABL. The data will be used for investigating droplet dynamics in the marine atmospheric boundary layer, characterizing the droplet surface flux source function, and determining the effect spray drops have on air-water surface exchange process...

The neutrally stable atmospheric surface layer is used as a physical model of a very high Reynolds number, canonical turbulent boundary layer. Challenges and limitations with this model are addressed in detail, including the inherent thermal stratification, surface roughness and non-stationarity of the atmosphere. Concurrent hot-wire and sonic anemometry data acquired in Utah's western desert p...

Time–frequency analysis of the dynamics of different wake vorticity structures, generated from a triangular prism orientated with its apex edge against the incoming wind, is carried out. Time–frequency analysis of time-series obtained with hot-wire anemometry is performed through a procedure based on proper orthogonal decomposition and spectral components are extracted with a technique that pro...
