Ice Particle Formation in the Lower Stratosphere
- 3 Downloads
Field observation data on aerosol ice particles in the lower stratosphere and the results of laboratory modeling of their microphysics are considered. A model of ice particle formation in the lower stratosphere is described using classical nucleation theory. The results of computational experiments indicate that the formation of the ice phase in supercooled ternary solutions can occur only if these liquid particles are supercooled (~3 K), which is consistent with the data from field observation data.
