An Artificially Induced Local Snowfall

Abstract

Observational evidence of a locally induced snowfall is presented. Local snow cover patterns are shown along with accompanying meteorological data which suggest that the precipitation process was initiated by the introduction of power plant and factory effluents into a supercooled fog and stratus cloud. Such an event poses a condition favorable for the application of the Bergeron-Findeisen theory. Likely sources of nuclei involved in the precipitation process are examined in relation to the snow cover patterns.
