From the formation of single flakes to the howling 70 km/h winds of lake effect snow storms to the destructive power of avalanches, intrepid researchers are bringing snow science into the 21st Century.

This knowledge seemed to be lost in Europe during the Dark Ages until the Renaissance when Leonardo recovered it.
