Download or read book Aerosol Cloud Interactions from Urban Regional to Global Scales written by Yuan Wang and published by Springer. This book was released on 2015-05-05 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The studies in this dissertation aim at advancing our scientific understandings about physical processes involved in the aerosol-cloud-precipitation interaction and quantitatively assessing the impacts of aerosols on the cloud systems with diverse scales over the globe on the basis of the observational data analysis and various modeling studies. As recognized in the Fifth Assessment Report by the Inter-government Panel on Climate Change, the magnitude of radiative forcing by atmospheric aerosols is highly uncertain, representing the largest uncertainty in projections of future climate by anthropogenic activities. By using a newly implemented cloud microphysical scheme in the cloud-resolving model, the thesis assesses aerosol-cloud interaction for distinct weather systems, ranging from individual cumulus to mesoscale convective systems. This thesis also introduces a novel hierarchical modeling approach that solves a long outstanding mismatch between simulations by regional weather models and global climate models in the climate modeling community. More importantly, the thesis provides key scientific solutions to several challenging questions in climate science, including the global impacts of the Asian pollution. As scientists wrestle with the complexities of climate change in response to varied anthropogenic forcing, perhaps no problem is more challenging than the understanding of the impacts of atmospheric aerosols from air pollution on clouds and the global circulation.

Download or read book Handbook of Air Quality and Climate Change written by Hajime Akimoto and published by Springer Nature. This book was released on 2023-10-29 with total page 1532 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook covers the air quality/air pollution from the viewpoints of causing impacts on human/ecosystem health and climate change. Traditionally, air pollution has been a concern mainly in terms of its impacts on human health, and it is still an immediate public and governmental concern in most Asian countries. However, in recent years so-called extreme weather events, such as stronger tropical cyclones, flooding, drought, and other phenomena, have been manifested causing tremendous losses of human lives and properties. Importantly, climate models tell us that such extreme weather events are actually induced by anthropogenic global warming. It has been pointed out that mitigation or alleviation of such climate change leading to the extreme weather events in the next 30 years can be possible only by reducing air pollutants with positive radiative forcing such as ozone or methane, which are called short-lived climate pollutants (SLCPs). Here, concerns about mitigation of air pollutants from the points of human health and climate change have merged. This book covers different kinds of air pollutants and radiative forcers and how they can be measured. It also mentions the situation of air pollutants in different continents and their regional impacts to human health, environment and economy as well as their link to extreme weather events. The book presents how the air pollution and climate change can be mitigated and how clean air technologies and international initiatives for co-controlling air pollution and climate change have been developed.

Download or read book Modeling of Regional Atmospheric Pollution written by Laurent Menut and published by John Wiley & Sons. This book was released on 2024-05-21 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the main concepts used to develop and implement chemistry-transport models to calculate the evolution of regional air pollution. Since physico-chemical principles are already widely presented in various works, the perspective chosen for this book concerns the modeling of these processes. As modeling can be a simplification of reality in a particular study framework, we will try to show whether the processes represented are well modeled or not. For each process, we will discuss the simplifying assumptions that have been made, the various possible ways for improvement and the impact of these simplifications on the desired results. General information on pollution is presented, followed by observations, legislation, modeling of meteorology and then chemistry-transport, anthropogenic and natural emissions, depots, validation of calculations, optimization and data assimilation.

Download or read book Urban Meteorology written by National Research Council and published by National Academies Press. This book was released on 2012-06-13 with total page 190 pages. 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.
