Abstract: Representations for the surface area of ice particles in terms of the projected area have been developed using two different methods. The first method uses ice particles that are imaged in situ and geometric calculations ...

Abstract: Ice crystal terminal velocities govern the lifetime of radiatively complex, climatologically important, low-latitude tropopause cirrus clouds. To better understand cloud lifetimes, the terminal velocities of low-latitude ...

Abstract: Ice crystal aggregates imaged by aircraft particle imaging probes often appear to be fractal in nature. As such, their dimensional properties, mass, and projected area can be related using fractal geometry. In cloud ...

Abstract: Cirrus clouds in mid- and high latitudes are frequently composed of bullet rosette? and column-shaped ice crystals, which can have hollow ends. Bullet rosette?shaped ice crystals are composed of a number of bullets radiating ...

Abstract: Cirrus clouds in the midlatitude and Arctic regions are often composed of bullet rosette?shaped ice crystals. Bullet rosette?shaped ice crystals are composed of a number of bullets radiating from a central point. The bullets ...
