Prepared by the Task Committee on Urban Aerodynamics of the Environmental Wind Engineering Committee of the Technical Council on Wind Engineering of ASCE. Urban Aerodynamics: Wind Engineering for Urban Planners and Designers introduces the basic tools and technology used by engineers to determine the effects of wind on city streets and structures. Familiarity with the fundamentals of urban aerodynamics offers many advantages to city planners and urban designers, most especially the opportunity to incorporate quantitative techniques into the design and development process. This volume traces the historical development of wind engineering techniques leading up to today's use of boundary layer wind tunnel studies and computational fluid dynamics assessments. Examples show the application of wind engineering to address urban issues such as pedestrian-level wind control, design for hurricane shelter, urban summer breeze penetration, winter wind shielding, the natural ventilation of buildings, and dispersion of airborne pollutants. Current tools and techniques for both qualitative and quantitative assessment of urban wind effects are reviewed, and an extensive list of references is included. This book is a compact essential reference for city planners, urban designers, and architects, as well as structural and wind engineers.

According to the United Nations, three out of five people will be living in cities worldwide by the year 2030. The United States continues to experience urbanization with its vast urban corridors on the east and west coasts. Although urban weather is driven by large synoptic and meso-scale features, weather events unique to the urban environment arise from the characteristics of the typical urban setting, such as large areas covered by buildings of a variety of heights; paved streets and parking areas; means to supply electricity, natural gas, water, and raw materials; and generation of waste heat and materials. Urban Meteorology: Forecasting, Monitoring, and Meeting Users' Needs is based largely on the information provided at a Board on Atmospheric Sciences and Climate community workshop. This book describes the needs for end user communities, focusing in particular on needs that are not being met by current urban-level forecasting and monitoring. Urban Meteorology also describes current and emerging meteorological forecasting and monitoring capabilities that have had and will likely have the most impact on urban areas, some of which are not being utilized by the relevant end user communities. Urban Meteorology explains that users of urban meteorological information need high-quality information available in a wide variety of formats that foster its use and within time constraints set by users' decision processes. By advancing the science and technology related to urban meteorology with input from key end user communities, urban meteorologists can better meet the needs of diverse end users. To continue the advancement within the field of urban meteorology, there are both short-term needs-which might be addressed with small investments but promise large, quick returns-as well as future challenges that could require significant efforts and investments.

For advanced undergraduate and beginning graduate students in atmospheric, oceanic, and climate science, Atmosphere, Ocean and Climate Dynamics is an introductory textbook on the circulations of the atmosphere and ocean and their interaction, with an emphasis on global scales. It will give students a good grasp of what the atmosphere and oceans look like on the large-scale and why they look that way. The role of the oceans in climate and paleoclimate is also discussed. The combination of observations, theory and accompanying illustrative laboratory experiments sets this text apart by making it accessible to students with no prior training in meteorology or oceanography. * Written at a mathematical level that is appealing for undergraduates and beginning graduate students * Provides a useful educational tool through a combination of observations and laboratory demonstrations which can be viewed over the web * Contains instructions on how to reproduce the simple but informative laboratory experiments * Includes copious problems (with sample answers) to help students learn the material.

Inhaltsangabe:Einleitung: In jüngster Vergangenheit werden in den verschiedenen Planungsdisziplinen wieder umweltrelevante Planungsdaten als Entwurfsparameter in den Vordergrund gerückt. Diese Entwicklung ist zu begrüßen und findet ihren Ursprung in der Energiekrise, die uns die Grenzen der Verfügbarkeit von Energie aufzeigte. Zunehmend wird wieder mit den natürlichen Kreisläufen geplant und nicht gegen sie. Die Berücksichtigung von Wind in der Gestaltung von Siedlungsraum stellt keine Errungenschaft unserer Zeit dar, sondern wurde bereits in der Vergangenheit vielfach angewendet. SCHÖNFELD spricht an, dass die Menschen der früheren Kulturen, aufgrund ihrer eingeschränkten Mittel keine andere Möglichkeit hatten, als mit ihren Bauten auf das Klima zu reagieren (sich sozusagen dem Klima baulich anzupassen) und mit Hilfe dieser Strategie ungünstige Bedingungen zu vermeiden. Richtet man einen Blick zurück in die Geschichte und vergleicht diese mit den aktuellen Tendenzen in der Stadtplanung, Architektur und Landschaftsarchitektur, so scheint es fast, als sei dieses Wissen, das man sich heute wieder aneignet, in Ansätzen schon seit Hunderten von Jahren vorhanden und nur durch die grenzenlose Verfügbarkeit von Energie in Vergessenheit geraten. So zeigt sich, dass in China Kao Gong Ji bereits um 500 v. Chr. ein Buch veröffentlichte, in dem er die Relevanz des Klimas für die Planung ansprach. Als Folge dieses Buches, das leider verloren ging, oder aufgrund anderer Erkenntnisse besitzt keine chinesische Stadtmauer eine Öffnung in Richtung der Wintermonsune nach Norden. PLATE verweist auf den Städteplaner und Architekt Hippodamus, der die Stadt Milet, nachdem sie während der Regentschaft von Perikles zerstört worden war, nach der Hauptwindrichtung orientiert wieder aufbaute. Dabei wurden die Straßen so angelegt, dass Winde von den Bergen und von der See frei in die Stadt einfließen konnten und somit für Kühlung sorgten. In seinen 23 v. Chr. veröffentlichten Büchern De architectura libri decem riet Vitruv, tiefliegende und nebelreiche Gebiete von der Bebauung auszuschließen und den Einfluss des Windes zu berücksichtigen. In welcher Weise dies jedoch geschehen sollte, verschwieg er. Laut FEZER handelt es sich bei der 1823 vom Arzt Bernhard Christoph Faust entworfenen Stadt um die erste, die nach klimatischen Idealvorstellungen konzipiert wurde. Wichtig war neben der Ost-West- Orientierung der Gebäude, um eine hohe Besonnung zu erhalten, dass Nord-Süd [...]

Urban Remote Sensing is designed for upper level undergraduates, graduates, researchers and practitioners, and has a clear focus on the development of remote sensing technology for monitoring, synthesis and modeling in the urban environment. It covers four major areas: the use of high-resolution satellite imagery or alternative sources of image date (such as high-resolution SAR and LIDAR) for urban feature extraction; the development of improved image processing algorithms and techniques for deriving accurate and consistent information on urban attributes from remote sensor data; the development of analytical techniques and methods for deriving indicators of socioeconomic and environmental conditions that prevail within urban landscape; and the development of remote sensing and spatial analytical techniques for urban growth simulation and predictive modeling.

This is the first in a new series of publications arlslng out of the work of the Committee on Challenges of Modern Society of the North Atlantic Treaty Organization. The CCMS was established in 1969 with a mandate to examine practical ways of improving the exchange of experience among mem ber nations of the Alliance in the task of creating a better envir onment for their societies. It was charged with considering "spe cific problems of the human environment with the deliberate objec tive of stimulating action by member governments". It may come as a surprise to some that NATO - generally thought of as being an organization devoted solely to matters of defence - should concern itself with the environment at all. But this is to overlook Article 2 of the North Atlantic Treaty of 1949, which expressly provides that member count ries should contribute towards the furt her development of peaceful and friendly internat ional relations by promoting conditions of stability and well being. This concern is reflected in many non-military areas, in addition to the environmental one. I wish the present volume, which has been edited by the Bel gian Prime Minister's Office for Science Policy Programming, every success.

Increasing urbanization throughout the world, the depletion of fossil fuels and concerns about global warming have transformed the city into a physical problem of prime importance. This book proposes a multi-disciplinary and systematic approach concerning specialities as different as meteorology, geography, architecture and urban engineering systems, all surrounding the essential problem of solar radiation. It collects the points of view of 18 specialists from around the world on the interaction between solar energy and constructions, combining territorial, urban and architectural scales to better regulate energetic efficiency and light comfort for the sustainable city. The main subjects covered are: measures and models of solar irradiance (satellite observations, territorial and urban ground measurements, sky models, satellite data and urban mock-up), radiative contribution to the urban climate (local heat balance, radiative-aerodynamics coupling, evapotranspiration, Urban Heat Island), light and heat modeling (climate-based daylight modeling, geometrical models of the city, solar radiation modeling for urban environments, thermal simulation methods and algorithms) and urban planning, with special considerations for solar potential, solar impact and daylight rights in the temperate, northern and tropical climates, and the requirement of urban solar regulation.

The first dealt with the nature debate for a complex of industrial and environ mental phenomena. Among these, Acid Rain in the of the problem, and culminated in the publication straightforward meaning of the words-rain and of Watt Committee Report No. 14 in 1984. That perhaps snow having a significantly high level of Report was divided into four sections, each of acidity-is of only limited importance. To represent which was prepared by a sub-group of the working this perspective, therefore, the Watt Committee Ex group: they dealt respectively with the fate of air borne pollution, vegetation and soils, fresh water ecutive decided that the study leading to the present Report should be entitled 'Air Pollution, Acid Rain and remedial strategy. In the second phase, these and the Environment'. sub-groups have brought their sections up-to-date The Watt Committee's interest in Acid Rain and a fifth sub-group was appointed to study arises from the fact that, among its causes, the buildings and non-living materials.
