Microphysical structure of a developing convective snow cloud simulated by an improved version of the multi‐dimensional bin model

A new version of the multi‐dimensional bin‐microphysics model, which employs four dimensions to represent ice‐particle properties (ice mass, solute mass, aspect ratio and volume), was developed. The model was incorporated into an adiabatic parcel model to simulate the developing stage of a convectiv...

Description
Summary:A new version of the multi‐dimensional bin‐microphysics model, which employs four dimensions to represent ice‐particle properties (ice mass, solute mass, aspect ratio and volume), was developed. The model was incorporated into an adiabatic parcel model to simulate the developing stage of a convective snow cloud observed over the Sea of Japan. The results suggest that crystals originating from deposition/condensation–freezing nuclei grow the fastest in the cloud, and isometric crystals among them effectively act as embryos of graupels.
