The investigation of ice formation found important applications in many different fields. For instance, the accretion of ice is a common occurrence on the aircraft, due to the high velocity and humidity, and low temperature at upper air. The detection of ice formation on aircrafts is a critical issue since not only the aerodynamics change, but there is also the possibility of ice liberation fro...

Cirrus clouds are composed of ice crystals condensed from humidity due to low temperature condition in the upper atmosphere. The microphysics of cirrus clouds including sizes and shapes of ice particles are not well understood but are important in climate modeling. Ice crystal will fall under gravitational sedimentation to reach terminal velocities which depend on the size, mass, and ice habit....

During the high velocity impact of an object on a solid covered with thin fluid layer, lubricated contact exists within short time in which liquid is squeezed out from contact. This important for e.g. grip shoes wet surfaces. We experimentally study squeeze flow such layers and find that amount viscous dissipation determines how much remains after kinetic energy impacting absorbed. For impacts ...

Arctic sea ice drift forecasts of 6 h-9 days for the summer of 2014 are generated using the Marginal Ice Zone Modeling and Assimilation System (MIZMAS); the model is driven by 6 h atmospheric forecasts from the Climate Forecast System (CFSv2). Forecast ice drift speed is compared to drifting buoys and other observational platforms. Forecast positions are compared with actual positions 24 h-8 da...

Concentric crater fill (CCF) occurs in the interior of impact craters in midto high latitudes on Mars and is interpreted to have formed by glacial ice flow and debris covering. We use the characteristics and orientation of deposits comprising CCF, the thickness of pedestal deposits in midto high-latitude pedestal craters (Pd), the volumes of the current polar caps, and information about regiona...
