Available in PDF, EPUB and Kindle. Book excerpt: All cloud and climate models assume ice crystals formed from frozen water droplets are pure even though cloud and haze drops are never pure. Prior experiments show that, during the freezing of solution drops, phase separation into pure ice and a freeze-concentrated solution takes place, potentially affecting the freezing of a solution droplet and its subsequent growth as an ice crystal (Bogdan and Molina 2017). We present measurements of ice crystal growth from frozen sodium chloride (NaCl) solution drops in the button electrode levitation (BEL) diffusion chamber at temperatures between -61°C and -40°C. Measured scattering diffraction patterns show that concentrated solution droplets remain unfrozen with classical diffraction fringes until the droplets freeze. Upon freezing, the scattering patterns become complex within 0.1 seconds which is in contrast with frozen pure water particles, which retain liquid-like scattering patterns for about a minute. After freezing, solution particles initially grow as spherical-like crystals, and then transition to faster growth indicative of a morphological transformation (such as the development of branching arms, Harrington and Pokrifka 2024). The measurements indicate that ice formed from solution droplets grows differently and has higher growth rates than ice formed from pure water droplets. We use these results to develop a power-law based parameterization that can be included in cloud models.

Download or read book Snow Crystals written by Kenneth G. Libbrecht and published by Princeton University Press. This book was released on 2021-12-21 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Despite substantial, cross-disciplinary interest in the subject as a scientific case study, surprisingly little has been written on the science of snowflakes and their formation. For materials scientists, snowflakes constitute archetypal examples of crystal growth; for chemists, the site of complex molecular dynamics at the ice surface. Physicists can learn from snowflake symmetry and self-assembly; geologists study snow as mineral crystals; and biologists can even gain insight into the creation of shape and order in organisms. In the humble snowflake are condensed many of the processes-many of them still not fully understood-that govern the organization of classical systems at all levels of the natural world. This book by Kenneth Libbrecht-inarguably the world's foremost expert on the subject-will be the authoritative text on the science of snow crystals. It will cover all of the physical processes that govern the life of a snowflake, including how snowflakes grow and why they have the shapes they do. It will also outline techniques for creating and experimenting with snow crystals, both with computer models and in the lab. Featuring hundreds of color illustrations, the book will be comprehensive and is sure to become definitive resource for researchers for years, if not decades, to come"--
