Ice Crystal Formation: Processes and Shapes

This lecture explores the formation of ice crystals, discussing the structure of ice, super-cooled water, and ice crystal formation in clouds. It covers the processes of ice crystal formation, including homogeneous and heterogeneous nucleation, as well as the growth of ice crystals and snowflakes. The lecture also delves into different types of ice crystal shapes and the processes of aggregation, such as riming and aggregation. Furthermore, it explains the significance of snow metamorphism, the growth of ice crystals, and the classification of ice crystals. The lecture concludes with a discussion on ice surface conditions and the microscopic mass transport in porous media.
