Formation process of branches of needle ice crystals grown from vapor
In-situ observations of needle ice crystals growing in air at 10^5 Pa at -7℃ and at about water saturation and above water saturation were performed to study the formation process of the branches of needle ice crystals. At about water saturation, six branches with boomerang-like facets are formed af...
