Mechanical properties of atmospheric ice
Cold Regions Science and Technology, 1986Abstract Mechanical properties of atmospheric ice obtained in a wind tunnel are measured. The ice is grown from supercooled droplets on a rotating aluminium cylinder of 31.5-mm diameter and 6.5-μm rugosity. Compressive strength is measured at two speeds of deformation (0.76 and 26 mm/min) for glaze and rime samples, as a function of air temperature ...

Applications: Atmospheric Ice Crystals
2003The aggregates (both external and internal) that were considered in Chap. 6 were not meant to simulate specific kinds of particles, but rather to illustrate the capabilities of the cluster model in association with the transition matrix approach in describing the optical properties of some system of interest. In the present chapter, on the contrary, we

Scheiner's Halo: Evidence for Ice Ic in the Atmosphere
Science, 1981Refraction of sunlight at the angle of minimum deviation between octahedral faces of crystals of ice Ic in the upper atmosphere could produce a halo around the sun or the moon at 27.46°. Crystals of hexagonal ice having low-index faces cannot produce a halo of this radius. It is therefore suggested that Scheiner's halo, which has been reported at least

Compressive strength of atmospheric ice
Cold Regions Science and Technology, 2007Abstract Accumulation of atmospheric ice on power transmission lines is a source of tremendous damage to power networks. Despite the longstanding problem of atmospheric icing on network equipment, the mechanical properties and behavior of this type of ice under various loading conditions are still unclear.

Melting of atmospheric ice particles
2022The transition from ice to liquid phase of precipitating particles in the atmospheric melting layer on their way down to the earth surface has high impact on cloud microphysical and precipitating processes. For many decades, this topic is investigated through theoretical modeling and experimentally. The theoretical descriptions are based on the general

Atmospheric icing sensors for UAV's
2013 IEEE 4th International Conference on Cognitive Infocommunications (CogInfoCom), 2013This paper exhibits significance of ice sensory in unmanned aerial vehicle (UAV) as remote monitoring unit and discuss the significant factors incorporated in the autopilot design implementation for reliable operation. UAVs' ice monitoring methodologies are discussed and suitable options are evaluated.

Ice detector estimation of atmospheric icing on a cable
Cold Regions Science and Technology, 1993Abstract Atmospheric icing is an important cause of damages to structures and power transmission lines in northern Quebec. An icing test line was set up on Mt. Valin (alt. 902 m) near Chicoutimi to measure icing loads on the type of stranded cables used on transmission lines.
