概要

• 論文の詳細を見る

• σ^* is the critical supersaturation where kinetic roughening takes place. When the supersaturation σ<γ^*, prismatic facets are formed at the tips of primary branches of dendritic ice crystal. Then, the side branches are formed as a result of the shape instability of the prismatic facets with changing supersaturation. In the next place, when the supersaturation σ>σ^*, the tip shape of primary branches of dendritic ice crystal becomes round. In this case, the side branches are formed as a result of the change in the tip width of primary branches with changing supersaturation. Snow crystals observed in Antarctica are discussed on the basis of these experimental results.
