CRYSTALLINE STRUCTURE OF ICE DEVELOPING BY ACCRETION OF SUPERCOOLED WATER DROPLETS ON A SINGLE WIRE AND GROWTH PROCESS OF RIME ON A SQUARE BOARD PLACED IN THE AIR FLOW CONTAINING SUPERCOOLED DROPLETS AND SNOW FLAKES

This paper discusses ice fabrics or crystalline structures of ice formed by accretion of supercooled water droplets. The structures, consisting of columnar grains, have been observed in laboratory settings. A rigid frame stretched with a fine metallic wire (.001 mm diameter) was placed on a microscope stage in such a way that the surface of stretched wire was brought into the focus of an objective lense of the microscope, which was placed in a wind tunnel where cold air containing supercooled water droplets was flowing continuously. The riming process on the stretched wire was recorded cinematographically through a microscope. On the summit of a mountain covered with snow, icing on structures is created not only by accretion of supercooled water droplets but also by adhering of snowflakes.
