Freezing Water and Supercooling: Anchor Ice and Frazil Ice
Abstract The supercooling of water in nature occurs more frequently than is generallyknown. It always takes place when still water is in process of being covered with thefirst ice needles. It is of even greater importance when ice formation takes place in running and turbulent water, in which case i...
