NettetJulian B. Murton, in Treatise on Geomorphology (Second Edition), 2024 4.23.3.7 Vapor-deposition ice. Vapor-deposition ice is a type of subsurface hoar frost that forms by the direct deposition of water vapor into ice within cracks open to the atmosphere, and within pores and cavities enclosed in frozen ground. Such ice grows where the mean water … NettetHoar frost occurs when a sub-zero surface comes into contact with moist air. The water vapour in the air turns directly into ice by sublimation forming a white crystalline ice coating which can normally be brushed off. … Hoar frost is not as dangerous as clear ice but may affect the lift characteristics of the wings.

Hoar frost, also hoarfrost, radiation frost, or pruina, refers to white ice crystals deposited on the ground or loosely attached to exposed objects, such as wires or leaves. They form on cold, clear nights when conditions are such that heat radiates into outer space faster than it can be replaced from nearby warm objects or brought in by the wind.
