A Method of Calculation Based on Wind Field Diagnosis Mode for Smoke

摘要

According to the characteristics of atmosphere environment, the relativity between the wind, temperature inversion layer and smoke screen dispersion are discussed. Based on analyzing atmosphere transportation and diffusion process, the application of a diagnosis mode to calculating the wind field of the release district, analyzes the dispersion characteristics of smoke source in the atmosphere, and brings up an imitation model of the dispersion of screening smoke. Compared with the gauss model, the research shows that this model possesses such advantages as high determinability and operability. The model can be applied to estimating the concentration of screening smoke and the attenuation of light intensity.
