Rain ice (juyuu, English: soft rime) is white and fragile of the ice layer frozen and adhered due to the collision of dense fog composed of supercooled water droplets against the object. It develops remarkably when the wind is weak in an environment with a temperature of -5 ° C. or less, and it is opaque because it contains many air bubbles, and it is white. It is a structure in which small granular ice agglomerates countlessly, it is brittle enough to collapse easily when touched by hand, and it easily falls when rocking an object attached with ice and ice. It grows like feathers towards the windward side, grows more upwind as the wind is stronger, this is also commonly called “shrimp tail”.
