A13B:
Atmospheric Ice Formation Processes and Impacts III Posters


Session ID#: 7816

Session Description:
Nucleation of ice crystals, with resultant effects on cloud properties, radiation, and precipitation, remains one of the least well-understood atmospheric phenomena. In recent years considerable new efforts to address major questions regarding ice nucleation and cloud glaciation have been pursued, using experimental, in situ and remote sensing observations, and modeling approaches.

We solicit submissions that advance our knowledge of the sources, emissions, and properties of specific types of ice nucleating particles (INP); the contributions from different ice nucleation mechanisms to cloud glaciation; observations of INP and INP-cloud interactions; secondary ice formation; the evolution of mixed-phase and cirrus clouds; observational or modeling studies of the impacts of glaciation on cloud properties, precipitation, radiation, and climate, from cloud to global scales; mechanistic studies, new theoretical treatments, or parameterizations of these processes; and new methods to better address these topics.

Ice Multiplication by Crystal Growth?Ice growing from the vapor along with tiny amounts of salt solution sheds free ice crystals, at -5C and saturation with respect to liquid water, in quiescent conditions. This is a more appealing explanation for the Hallett-Mossop effect than rime splintering, if it occurs primarily at temperatures near -5C. (79795)
