This book was released on 2018 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid expansion of urbanization has drastically changed regional landscapes around the globe. While only a small percentage of the Earth's surface is covered by cities, more than half of the world's population resides within their boundaries. Urban climate studies have documented temperature, precipitation, and aerosol anomalies near cities. Consequently, cities are simultaneously vulnerable to and the cause of shifts in climate regimes. Urban climate research, however, has largely ignored the aggregate effects of urban clusters, or multiple adjacent cities, on weather and climate at a regional scale. Research shows that cities may impact atmospheric circulation outside of city boundaries as well as precipitation type during winter weather events. Understanding how and where these impacts are prone to occur is valuable in helping communities prepare for weather events and the development of mitigation strategies during continued growth. This dissertation investigates how urban clusters impact regional climate, particularly how winter precipitation type is modified by cities. The overarching goal is to determine, not only these effects but, whether the current observational network, numerical modeling tools, and postprocessing techniques are viable in assessment of urban-scale processes during transitional precipitation events. Results show that urban environments increase hydrometeor exposure to above freezing temperatures causing increased melting, mixed precipitation events are more likely to occur within cities than in rural areas, and the existence of nearby, but non-adjacent, cities is a factor in the magnitude of other urban heat islands.

Available in PDF, EPUB and Kindle. Book excerpt: Urban Climates is the first full synthesis of modern scientific and applied research on urban climates. The book begins with an outline of what constitutes an urban ecosystem. It develops a comprehensive terminology for the subject using scale and surface classification as key constructs. It explains the physical principles governing the creation of distinct urban climates, such as airflow around buildings, the heat island, precipitation modification and air pollution, and it then illustrates how this knowledge can be applied to moderate the undesirable consequences of urban development and help create more sustainable and resilient cities. With urban climate science now a fully-fledged field, this timely book fulfills the need to bring together the disparate parts of climate research on cities into a coherent framework. It is an ideal resource for students and researchers in fields such as climatology, urban hydrology, air quality, environmental engineering and urban design.
Download or read book The Urban Climate written by Helmut E. Landsberg and published by Academic Press. This book was released on 1981-08-28 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Urban Climate aims to summarize analytical studies directed toward physical understanding of the rural-urban differences in the atmospheric boundary layer. Attempts to quantify conditions have met with some success. There is certainly a clear understanding of the physical relations that create the climatic differences of urbanized areas. Although some of the earlier classical studies are cited here, the emphasis is on the work done during the last decade and a half. This volume comprises 11 chapters, beginning with an introductory chapter discussing the literature surrounding the topic, its historical development, and the problem of local climate modification. The second chapter presents an assessment of the urban atmosphere on a synoptic and local scale, and examines the observational procedures involved. The following chapters then go on to discuss urban air composition; urban energy fluxes; the urban heat island; the urban wind field; models of urban temperature and wind fields; moisture, clouds, and hydrometeors; urban hydrology; special aspects of urban climate; and finally, urban planning. This book will be of interest to practitioners in the fields of meteorology, urban planning, and urban climatology.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Impacts of Land Cover Change on Climate Over China written by Liang Chen and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: China has experienced substantial land cover changes for hundreds of years, such as deforestation, agricultural expansion, and urbanization. These land cover changes can modify the physical and thermodynamic characteristics of the land surface, thereby influencing climate at regional or broader scales. In this dissertation, I first examine the performance of state-of-the-art general circulation models to assess their ability to skillfully simulate climate in China. Then, the CESM and WRF models are used to investigate specific biogeophysical effects of land cover changes-including vegetation changes and urbanization. Multimodel ensembles of CMIP5 models are found to well capture the spatial patterns of seasonal and annual temperature and precipitation. However, they contain substantial cold biases over the Tibetan Plateau especially in the cold season, and overestimate precipitation in most regions of China, especially along the eastern edge of the Tibetan Plateau. Four CMIP5 models are identified due to their better simulation of historical surface air temperature variability over China: MPI-ESM-LR, CanESM2, MIROC-ESM, and CCSM4. Focusing on CCSM4, a subset of CESM, sensitivity analyses indicate that, for historical vegetation changes, summer temperatures are regulated by evapotranspiration, which can decrease the diurnal temperature range. Decreases in winter temperature over northern China are mainly influenced by surface albedo changes. Vegetation changes do not exhibit significant impacts on summer precipitation or the East Asian summer monsoon, but could strengthen East Asian winter monsoon and decrease winter precipitation in southern China. When urbanization is included, there are more significant and extensive impacts on temperature and precipitation in China, including greatly increased minimum temperatures and influences on East Asian Monsoon. Future climate projection reveals that urbanization produces strong warming effects, up to 1.9°C at local scales, which is comparable to the magnitude of greenhouse gas forcing under the RCP 4.5 scenario. The impacts of urbanization on precipitation show a combined effect from local moisture deficits and large-scale circulation changes. In summation, land cover changes play an important role in climate over China. Not only vegetation changes, but urbanization also should be included in model simulations to provide realistic and complete climatic impacts of land cover changes.

Download or read book Regional scale Land climate Interactions and Their Impacts on Air Quality in a Changing Climate written by Xiaoyan Jiang (doctor of geological sciences.) and published by . This book was released on 2010 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land surface areas, which represent approximately 30% of the Earth's surface, contribute largely to the complexity of the climate system by exchanging water, energy, momentum, and chemical materials with the overlying atmosphere. Because of the highly heterogeneous nature of the land surface and its rapid transformation due to human activities, future climate projections are less certain on regional scales than for the globe as a whole. The work presented in this dissertation is focused on a better understanding of regional-scale land--atmosphere interactions and their impacts on climate and air quality. Specifically, I concentrate my research on three typical regions in the United States (U.S.): 1) the Central U.S. (representing transition zones between arid and wet climates); 2) the Houston metropolitan region (representing a major urban area); and 3) the eastern U.S. (representing temperate forested regions). These regions are also chosen owing to the consideration of data availability. The first study concerns the roles of vegetation phenology and groundwater dynamics in regulating evapotranspiration and precipitation over the transition zones in summer months. It is found that the warm-season precipitation in the Central U.S. is sensitive to latent heat fluxes controlled by vegetation dynamics. Groundwater enhances the persistence of soil moisture memory from rainy periods to dry periods by transferring water to upper soil layers through capillary forces. Enhancement in soil moisture facilitates vegetation persistence in dry periods, producing more evaporation to the atmosphere and resulting in enhanced precipitation, which then increases soil moisture. The second study compares the impacts of future urbanization and climate change on regional air quality. The results show that the effect of land use change on surface ozone (O3) is comparable to that of climate change, but the details differ across the domain. The third study deals with the formation and distributions of secondary organic aerosols (SOA) -- a largely overlooked but potentially important component in the climate system. Under future different climate scenarios, I found that biogenic emissions -- an important precursor of SOA -- are expected to increase everywhere over the U.S., with the largest increase found in the southeastern U.S. and the northwestern U.S., while changes in SOA do not necessarily follow those in biogenic emissions. Other factors such as partitioning coefficients, atmospheric oxidative capability, primary organic carbon, and anthropogenic emissions also play a role in SOA formation. Direct and indirect impacts from climate change complicate the future SOA formation.

Download or read book Urbanization under a Changing Climate written by Jianxun He and published by MDPI. This book was released on 2021-06-18 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to the increasing urbanization, advances in the science of urban hydrology have improved urban water system management, creating more livable cities in which public safety and health, as well as the environment, are protected. The ultimate goal of urban water management is to mimic the hydrological cycle prior to urbanization. On top of urbanization, climate change, which has been demonstrated to alter the hydrological cycle in all respects, has introduced additional challenges to managing urban water systems. To mitigate and adapt to urbanization under a changing climate, understanding key hydrologic components should expand to include complex issues brought forth by climate change. Thus, effective and efficient measures can be formulated. This Special Issue of Water presents a variety of research papers that span a range of spatial and temporal scales of relevance in different societies’ efforts in adapting to the eminent changes in climate and the continuous changes in the landscape. From mitigating water quality in permeable pavements and bioretention swales to understanding changes in groundwater recharge in large regions, this Special Issue examines the state-of-the-art in sustainable urban design for adaptation and resiliency.
Download or read book Attribution of Extreme Weather Events in the Context of Climate Change written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-07-28 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: As climate has warmed over recent years, a new pattern of more frequent and more intense weather events has unfolded across the globe. Climate models simulate such changes in extreme events, and some of the reasons for the changes are well understood. Warming increases the likelihood of extremely hot days and nights, favors increased atmospheric moisture that may result in more frequent heavy rainfall and snowfall, and leads to evaporation that can exacerbate droughts. Even with evidence of these broad trends, scientists cautioned in the past that individual weather events couldn't be attributed to climate change. Now, with advances in understanding the climate science behind extreme events and the science of extreme event attribution, such blanket statements may not be accurate. The relatively young science of extreme event attribution seeks to tease out the influence of human-cause climate change from other factors, such as natural sources of variability like El Niño, as contributors to individual extreme events. Event attribution can answer questions about how much climate change influenced the probability or intensity of a specific type of weather event. As event attribution capabilities improve, they could help inform choices about assessing and managing risk, and in guiding climate adaptation strategies. This report examines the current state of science of extreme weather attribution, and identifies ways to move the science forward to improve attribution capabilities.
