Surface micromorphology of columnar ice crystals growing in air at high and low supersaturations
The growth mechanisms of long prisms with skeletal structures precipitating in the polar regions are studied by observing the surface micromorphology of columnar ice crystals growing in air at high and low supersaturations. It is concluded that long hollow prisms, that is, long prisms with large ske...

The growth mechanisms of long prisms with skeletal structures precipitating in the polar regions are studied by observing the surface micromorphology of columnar ice crystals growing in air at high and low supersaturations. It is concluded that long hollow prisms, that is, long prisms with large skeletal structures grow by a two-dimensional nucleation mechanism under supersaturation above about 10%, while long prisms with small skeletal structures grow by a screw dislocation mechanism under supersaturation below about 2%. |
