Using analytical solutions of simple model diffusion problems, we have studied the process of formation of a large-scale spot-like pollution structure of the underlying surface by a powerful high-altitude finite source. We have established a criterion for the appearance of a spot-like pollution structure in case of presence such a source which is defined by the ratio of time of source activity to characteristic time of periodic change of intensity of vertical turbulent mixing in the atmospheric boundary layer.References
