Bullet-rosette ice crystal |
Parent topic |
Fig. 2. The bullet-rosette is a dominant ice crystal form found in cirrus clouds (for example, Baran AJ 2004, Parungo F 1993, Heymsfield AJ 1975). Left: a 3D, computer-generated model featuring 6 "bullets". See also 3D models of other configurations of the bullet-rosette, represented by different surface functions, in Fig. 1 of Chiruta M and Wang (2003). Middle: an image taken in situ 03 May 2006 during the CAESAR campaign (Cirrus and Anvils: European Satellite and Airborne Radiation measurement project) with a cloud particle imaging (CPI) probe (for example, Lawson RP et al 2001). Right: a microphotograph of a Formvar replica of a bullet-rosette ice crystal sampled in a cirrostratus cloud at -20°C, bar = 100 µm (Heymsfield AJ 1975, Fig. 1B, reproduced with permission).
