Abstract:

A study of turbulent diffusion in the surface bounday layer is conducted to determine the effects of the wind speed on the distribution of sulfur dioxide SO2 with time. With the use of autocorrelograms and the spectra of wind speed and SO2, similarities between these scalar quantities under varying stability conditions are investigated. Pollution monitoring sites in the Salt Lake Valley vicinity and St. Louis are used. Under stable conditions, the auto-correlograms and the spectra of wind speed and SO2 are similar in many respects. The auto-correlograms show very similar coefficients up to a time lag of 13 hours, and the spectra shows similar peaks near periods of 24, 12 and 8 hours. The wind speed peaks are more prominent, which suggests the spectrum of SO2 is affected by the spectrum of the wind speed for periods equal to or less than 24 hours. Forecasting the SO2 spectrum from the wind speed spectrum is possible for the periods near 24 and 12 hours. The similarity between the wind speed and SO2 auto-correlograms and spectra decreases as stability decreases. In the stable periods, the effect of the large scale motions is suppressed, and more energy is found in the higher frequencies than in neutral or unstable periods. Author
