Book Description
Abstract: The supersaturation of water vapor required for spontaneous formation of nuclei was measured in the temperature range between +35° and -75° C. The influence of the presence of ions on the condensation process was found to disappear and a break in the critical supersaturation as a function of temperature curve was sound at -62° C. In addition, the condensate particles were observed to scintillate at -62° C or lower. A modified form of the Volmer and the Becker-Döring equations for rate of nuclei formation is presented and compared with the experimental data. The temperature range of droplet-nucleus formation and crystal-nucleus formation are considered as two distinct (not overlapping) temperature regions separated by the melting point (-62° C) of a two-dimensional surface phase.

Book Description
Principles of Snow Hydrology describes the factors that control the accumulation, melting and runoff of water from seasonal snowpacks over the surface of the earth. The book addresses not only the basic principles governing snow in the hydrologic cycle, but also the latest applications of remote sensing, and techniques for modeling streamflow from snowmelt across large mixed land-use river basins. Individual chapters are devoted to climatology and distribution of snow, snowpack energy exchange, snow chemistry, ground-based measurements and remote sensing of snowpack characteristics, snowpack management, and modeling snowmelt runoff. Many chapters have review questions and problems with solutions available online. This book is a reference book for practicing water resources managers and a text for advanced hydrology and water resources courses which span fields such as engineering, earth sciences, meteorology, biogeochemistry, forestry and range management, and water resources planning.

Book Description
Topics in Current Aerosol Research deals with the fundamental aspects of aerosol science, with emphasis on experiment and theory describing highly dispersed aerosols (HDAs) as well as the dynamics of charged suspensions. Topics covered range from the basic properties of HDAs to their formation and methods of generation; sources of electric charges; interactions between fluid and aerosol particles; and one-dimensional motion of charged cloud of particles. This volume is comprised of 13 chapters and begins with an introduction to the basic properties of HDAs, followed by a discussion on the formation of condensation HDAs. Some of the methods of generation of HDAs are considered, including atomization, physical condensation of vapor, and chemical reactions in the gas phase are considered. A ""transport"" model for electrically charged aerosols is described. Subsequent chapters explore methods of investigation of HDAs in suspended state and based on particle precipitation; transfer processes in HDAs, including mass transfer, charge transfer, momentum transfer, and heat transfer; and charging of particulate matter by collection. This book will be a useful resource for practicing scientists and graduate students in such widely diverse fields as physics, physical chemistry, meteorology, geophysics, astronomy, chemical engineering, mechanical engineering, aerospace engineering, environmental sciences, and medicine.
