Models of smoke plumes from high-altitude sources

摘要

Models of estimating the emissions from thermal power plants in the lower atmosphere using satellite information are presented. Satellite images of smoke plumes from pipes of thermal stations can be used to quickly receive in visual form the current information about the plumes. The equations of hydro-and thermo-dynamics of the atmosphere are used as additional conditions in the estimation models. A numerical model is proposed for restoring the characteristics of the active phase of smoke plume ascents from high-altitude sources, and the results of calculations of these parameters for a thermal power plant in Novosibirsk are presented. This approach is shown to be efficient in the winter period, when large amounts of emissions of smoke mixtures are characteristic and the shadows of their plumes on the earth's surface stand in marked contrast. The results of the research can be used to monitor the negative impact of industrial enterprises on the environment and to assess possible harm to public health.
