An assessment is made of potential atmospheric effects that might be caused by the dissipation into the air of waste heat from large electric power generating complexes. The assessment is based on three components: (1) an estimate of the thermal and moisture perturbation on the atmosphere that might be expected from power generating facilities, (2) a search for observations of how nature responds to perturbations of this kind, and (3) interpretation of numerical experiments dealing with atmospheric processes using similar perturbations. It is concluded that there is a strong possibility that large power complexes (20,000 MWe) will cause unacceptable disturbances in the atmosphere, such as modification of rain and cloudiness patterns. 40 pp. Ref.
