A new portable, vertically-diverging wind tunnel was developed for studying melting of natural snowflakes and snow crystals during their free fall under controlled condition of the air stream. Using the tunnel, their size and fall velocity were measured and the regression equations were obtained. Their observed melting time depended only weakly with the size suggesting the possibility of internal melting due to air flow through their structure. Rotating and orbiting motions were commonly detected with snow crystals. Disruption was found frequently towards the end of melting of both snowflakes and ice crystals and resulted in instability in their suspension. A theoretical development was carried out for melting snowflakes and ice crystals considering their non-spherical shape. A new simple model of snowflake melting had been developed and was applied to a representative atmospheric condition. Comparison of the model behaviors of radar bright bands suggested that the shape and its development as well as size during aggregation play important roles in the bright band mechanism. The model predicts that the higher the snowfall rate, the larger the reflectivity increase and the lower the altitude of the bright band center. (Author).

A definitive new investigation of the science of snowflakes by the world’s leading expert A snowflake’s sophisticated symmetry emerges when crystalline ice grows from water vapor within the winter clouds. While certain iconic snowflake shapes are visually familiar to us, microscopic close-ups of falling snow reveal a rich menagerie of lesser-known forms, including slender needle clusters, hollow columns, bullet rosettes, triangular crystals, and exotic capped columns. What explains the myriad and unusual structures of snowflakes that materialize under different atmospheric conditions? In Snow Crystals, Kenneth Libbrecht delves into the science of snowflakes, examining why ice crystals grow the way they do, how patterns emerge, and what they illuminate about the fundamental physics of crystal growth, structure formation, and self-assembly. Libbrecht—the world’s foremost expert on snowflakes—describes the full range of physical processes underlying their occurrence. He explores such topics as the centuries-long development of snow crystal science, the crystalline structure of ice, molecular dynamics at the ice surface, diffusion-limited growth, surface attachment kinetics, computational models of snow crystal growth, laboratory techniques for creating and studying snow crystals, different types of natural snowflakes, and photographing snow crystals. Throughout, Libbrecht’s extensive detailed discussions are accompanied by hundreds of beautiful full-color images. From the molecular dynamics of surface premelting to the aerodynamics of falling snow, Snow Crystals chronicles the continuing quest to fully understand this fascinating phenomenon.

Cloud physics has achieved such a voluminous literature over the past few decades that a significant quantitative study of the entire field would prove unwieldy. This book concentrates on one major aspect: cloud microphysics, which involves the processes that lead to the formation of individual cloud and precipitation particles. Common practice has shown that one may distinguish among the following additional major aspects: cloud dynamics, which is concerned with the physics responsible for the macroscopic features of clouds; cloud electricity, which deals with the electrical structure of clouds and the electrification processes of cloud and precipitation particles; and cloud optics and radar meteorology, which describe the effects of electromagnetic waves interacting with clouds and precipitation. Another field intimately related to cloud physics is atmospheric chemistry, which involves the chemical composition of the atmosphere and the life cycle and characteristics of its gaseous and particulate constituents. In view of the natural interdependence of the various aspects of cloud physics, the subject of microphysics cannot be discussed very meaningfully out of context. Therefore, we have found it necessary to touch briefly upon a few simple and basic concepts of cloud dynamics and thermodynamics, and to provide an account of the major characteristics of atmospheric aerosol particles. We have also included a separate chapter on some of the effects of electric fields and charges on the precipitation-forming processes.
