Abstract
Heavy corona losses have been observed during snowstorms, particularly in Canada. The amount of these losses sometimes exceeds those during rainstorms. A tentative explanation is given based on the consideration of the ``effective dielectric constant'' during precipitation. Calculations and model measurements indicate a tremendous difference between rain and snow. The surface potential gradient during heavy snowstorms may be increased by as much as 10 to 20%.Keywords
