Book excerpt: Ice is one of the most abundant and environmentally important materials on Earth, and its unique and intriguing physical properties present fascinating areas of study for a wide variety of researchers. This book is about the physics of ice, by which is meant the properties of the material itself and the ways in which these properties are interpreted in terms of water molecules and crystalline structure. Although ice has a simple crystal structure its hydrogen bonding results in unique properties, which continue to be the subject of active research. In this book the physical principles underlying the properties of ice are carefully developed at a level aimed at pure and applied researchers in the field. Important topics like current understandings of the electrical, mechanical, and surface properties, and the occurrence of many different crystalline phases are developed in a coherent way for the first time. An extensive reference list and numerous illustrations add to the usefulness and readability of the text.

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.

This book was released on 2010-06-25 with total page 975 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 addi tional major aspects: cloud dynamics, which is concerned with the physics respon sible for the macroscopic features of clouds; cloud electricity, which deals with the electrical structure of clouds and the electrification processes of cloud and precipi tation 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 ofthe 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.

Available in PDF, EPUB and Kindle. Book excerpt: In-situ measurements suggest that heterogeneous nucleation is the dominant ice formation mechanism in the upper atmosphere. Clouds formed heterogeneously typically contain lower ice concentrations and larger crystals than those formed homogeneously. Because heterogeneous ice formation occurs at lower ice supersaturations than homogeneous freezing of supercooled drops, sufficient heterogeneous freezing can suppress or eliminate the homogeneous freezing process. The difference in freezing process may significantly alter the radiative properties of and particle sedimentation rates from cirriform clouds. The underlying physical processes influencing the competition between heterogeneous and homogeneous nucleation remain poorly understood. One such process that may be of importance is surface kinetic resistance to ice vapor growth and its dependence on particle shape evolution, which is investigated in this thesis using the Kinetically Limited Adaptive Habit (KLAH) growth method in a Lagrangian parcel model framework.The KLAH model predicts axis-dependent growth efficiencies that allow for particle shape to evolve in time. After nucleation, ice particles become increasingly less isometric as they grow. This non-linearly increases the vapor flux to the semi-major axis, increasing the rate at which vapor is depleted from the ambient environment. We show that, in some cases, more surface resistance may in fact accelerate this increase in the growth rate. As a result, fewer heterogeneously-nucleated ice crystals are required to suppress homogeneous nucleation. This may help to explain the relative dominance of heterogeneous nucleation in the upper atmosphere. Furthermore, we show that simpler treatments of surface kinetics are unable to capture this effect, and may lead to both over- and under-predictions of ice concentration while also missing the evolution of ice particle shape that occurs above the cloud-base nucleation zone.

Available in PDF, EPUB and Kindle. Book excerpt: Clouds affect our daily weather and play key roles in the global climate. Through their ability to precipitate, clouds provide virtually all of the fresh water on Earth and are a crucial link in the hydrologic cycle. With ever-increasing importance being placed on quantifiable predictions - from forecasting the local weather to anticipating climate change - we must understand how clouds operate in the real atmosphere, where interactions with natural and anthropogenic pollutants are common. This textbook provides students - whether seasoned or new to the atmospheric sciences - with a quantitative yet approachable path to learning the inner workings of clouds. Developed over many years of the authors' teaching at Pennsylvania State University, Physics and Chemistry of Clouds is an invaluable textbook for advanced students in atmospheric science, meteorology, environmental sciences/engineering and atmospheric chemistry. It is also a very useful reference text for researchers and professionals.

Available in PDF, EPUB and Kindle. Book excerpt: "Ice crystals, with their myriad shapes, sizes and densities, play an important role in the formation, evolution and subsequent impact of ice and mixed-phase clouds on weather and climate. There are numerous pathways through which ice crystals nucleate, grow and dissipate. Although many of these are understood theoretically and have been simulated in the laboratory and cloud chambers, they are less well documented in natural clouds. The challenges of making measurements from moving platforms in an environment that is spatially inhomogenous and temporally unsteady, as well as sometimes at high altitudes and in clouds with icing potential makes these clouds difficult to observe. Nevertheless, the importance of ice clouds on climate and the hydrological cycle compels us to better understand ice processes through improved measurements over as broad of a temporal and geographical scale as possible. This monograph represents a collection of articles that do exactly that."-- Book jacket.
