Growth Processes of Snow.

The growth of snow in winter storms is studied via observational and theoretical techniques. A new flight procedure termed the Advecting Spiral Descent (ASD) was employed by AFGL's instrumented C-130 aircraft to observe the height evolution of snow size spectra. These observations reveal that s...

Description
Summary:The growth of snow in winter storms is studied via observational and theoretical techniques. A new flight procedure termed the Advecting Spiral Descent (ASD) was employed by AFGL's instrumented C-130 aircraft to observe the height evolution of snow size spectra. These observations reveal that snow growth goes through three distinct stages: a vapor deposition stage, an aggregation stage and a secondary ice particle production stage. Theoretical models are used to simulate the observations of snow growth. These indicate that the secondary ice crystal production is due to the collisional breakup of snowflakes.
