Download or read book Microphysical Impact of Cloud Seeding on Winterime Orographic Clouds Observed During SNOWIE written by Melinda Hatt and published by . This book was released on 2019 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water supplies in the western U.S. rely heavily on mountain snowpack. Winter orographic cloud seeding is one potential approach to alleviate increasing demands on water supplies by increasing the amount of snowfall in mountain regions. The hypothesis behind glaciogenic cloud seeding is that by introducing an ice nucleating particle, in this case silver iodide (AgI), into a cloud containing supercooled liquid water, ice crystals will form and grow to sizes large enough to fall as precipitation, thus increasing the amount of precipitation fallout. SNOWIE, a recently completed field measurements campaign, provides the first-ever direct, unambiguous observations confirming this chain of events following the introduction of AgI into a supercooled orographic cloud. The analysis presented here investigates four cases during SNOWIE and analyzes in-situ measurements taken within seeded and non-seeded regions of cloud to evaluate the microphysical impact of cloud seeding, and examines the evolution of these characteristics within seeded plumes. A simple advection model is developed and used to predict the location of AgI plumes downwind of the release location. The model output is overlaid on flight tracks from the University of Wyoming King Air (UWKA) to determine when the aircraft likely passed through seeded plumes. Each of the cases presented show indication of seeding impact from radar reflectivity measurements by the Wyoming Cloud Radar and in-situ measurements from instruments on board the UWKA. An increase 10 L−1 or more of ice crystal concentration, or 0.1 g/m3 of ice water content, was measured within regions where the AgI plumes were expected to be located based on the advection model compared to the natural cloud, giving indication that ice was produced as a result of cloud seeding. Many of these regions also displayed an increase in ice content by roughly 0.1 g/m3 over the 40- to 90-minute observation period, along with an increase in particle size, suggesting that these ice crystals grew in size after their initial formation. In many instances, decreasing liquid water measurements to near zero imply that the liquid within these regions was depleted by the growing ice crystals through riming and deposition. Radar measurements showing an increase in reflectivity near the surface in these regions over time indicate that these large ice crystals fell toward the surface. These observations together imply that the ice crystals that were formed as a result of cloud seeding grew to sizes large enough to fall as snow.

Available in PDF, EPUB and Kindle. Book excerpt: The growing problem of changing environmental conditions caused by climate destabilization is well recognized as one of the defining issues of our time. The root problem is greenhouse gas emissions, and the fundamental solution is curbing those emissions. Climate geoengineering has often been considered to be a "last-ditch" response to climate change, to be used only if climate change damage should produce extreme hardship. Although the likelihood of eventually needing to resort to these efforts grows with every year of inaction on emissions control, there is a lack of information on these ways of potentially intervening in the climate system. As one of a two-book report, this volume of Climate Intervention discusses albedo modification - changing the fraction of incoming solar radiation that reaches the surface. This approach would deliberately modify the energy budget of Earth to produce a cooling designed to compensate for some of the effects of warming associated with greenhouse gas increases. The prospect of large-scale albedo modification raises political and governance issues at national and global levels, as well as ethical concerns. Climate Intervention: Reflecting Sunlight to Cool Earth discusses some of the social, political, and legal issues surrounding these proposed techniques. It is far easier to modify Earth's albedo than to determine whether it should be done or what the consequences might be of such an action. One serious concern is that such an action could be unilaterally undertaken by a small nation or smaller entity for its own benefit without international sanction and regardless of international consequences. Transparency in discussing this subject is critical. In the spirit of that transparency, Climate Intervention: Reflecting Sunlight to Cool Earth was based on peer-reviewed literature and the judgments of the authoring committee; no new research was done as part of this study and all data and information used are from entirely open sources. By helping to bring light to this topic area, this book will help leaders to be far more knowledgeable about the consequences of albedo modification approaches before they face a decision whether or not to use them.

This book was released on 2004-01-16 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The weather on planet Earth is a vital and sometimes fatal force in human affairs. Efforts to control or reduce the harmful impacts of weather go back far in time. In this, the latest National Academies' assessment of weather modification, the committee was asked to assess the ability of current and proposed weather modification capabilities to provide beneficial impacts on water resource management and weather hazard mitigation. It examines new technologies, reviews advances in numerical modeling on the cloud and mesoscale, and considers how improvements in computer capabilities might be applied to weather modification. Critical Issues in Weather Modification Research examines the status of the science underlying weather modification in the United States. It calls for a coordinated national research program to answer fundamental questions about basic atmospheric processes and to address other issues that are impeding progress in weather modification.

Available in PDF, EPUB and Kindle. Book excerpt: Mountain Geography is a comprehensive resource that gives readers an in-depth understanding of the geographical processes that occur in the world's mountains and the impact of these regions on culture and society. The volume begins with an introduction that defines mountains, followed by a comprehensive treatment of their physical geography, including origins, climatology, snow and ice, landforms and geomorphic processes, soils, vegetation, and wildlife. The concluding chapters discuss the human geography of mountains and our attitudes toward them, populations in the mountain regions and their livelihoods and interactions within dynamic environments, the diversity of mountain agriculture, and the challenges of sustainable mountain development. -- Book Jacket.
