| Abstract: | Abstract Observations of parhelia at Newmarket, Ontario on December 10, 1977 support an earlier suggestion regarding observations made in Toronto on January 22 of the same year. Parhelia were found to occur in the planetary boundary layer (PBL), particularly during the morning hours under blowing snow conditions on clear, cold (ca —17°C) winter days. Thus parhelia which occur in southern Ontario during the winter months can develop in the PBL without the presence of cirrostratus‐type clouds. |
