Aerial Smoke Plume Observations and Surface-Layer Turbulence Measurements. Part 2. Wind and Temperature Spectral Analysis. Project WIND. Phase 4, Dispersion Study: AMADEUS
Abstract
This data report contains results from selected time series and spectral analyses of the turbulent wind and temperature measurements performed during the AMADEUS Smoke and Diffusion Tests of Project WIND, Phase IV, which took place near Read Bluff, California, during the period between 3 Sep and 7 Oct 1985. Part 2 of this study provided time series plots of the turbulent (10 Hz block-averaged) wind and temperature signals as recorded by sonic- anemometers/thermometers at the 7-m level above the Meadow Brook Valley floor during the AMADEUS trials. The time series are further processed into energy spectra for the three wind components (u', r', w') and fluctuating temperature (T') and are presented together with their relevant scaling parameters calculated by the correlation method. The time series and spectra provide flow and diffusion modellers of the AMADEUS experiments with an insight in the turbulent scales and energies most responsible for the observed flow and diffusion processes. They also provide high-resolution boundary-layer flow and turbulence measurements for model simulation of the individual experiments. (edc)
