Yet, no one has been able to explain why such changes in temperature yield such dramatic alterations in snowflake structure.
If this sharpening effect occurs at other temperatures, which is likely, then it explains how changes in temperature can yield such widely varying snowflake structures. "The sharpening effect can yield thin plates or slender columns just by changing directions.
"A lot of chemistry occurs on ice surfaces," notes Travis Knepp of Purdue University, West Lafayette, Ind., a doctoral candidate in analytical chemistry who studies the basics of snowflake structure to gain more insight into the dynamics of ground-level, or "tropospheric," ozone depletion in the Arotic.
