Download or read book Modern Climatology written by Shih-Yu (Simon) Wang and published by IntechOpen. This book was released on 2012-03-09 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climatology, the study of climate, is no longer regarded as a single discipline that treats climate as something that fluctuates only within the unchanging boundaries described by historical statistics. The field has recognized that climate is something that changes continually under the influence of physical and biological forces and so, cannot be understood in isolation but rather, is one that includes diverse scientific disciplines that play their role in understanding a highly complex coupled "whole system" that is the earth's climate. The modern era of climatology is echoed in this book. On the one hand it offers a broad synoptic perspective but also considers the regional standpoint, as it is this that affects what people need from climatology. Aspects on the topic of climate change - what is often considered a contradiction in terms - is also addressed. It is all too evident these days that what recent work in climatology has revealed carries profound implications for economic and social policy; it is with these in mind that the final chapters consider acumens as to the application of what has been learned to date.

Download or read book Influence of the Sea Surface Temperature Decadal Variability on Tropical Precipitation: West African and South American Monsoon written by Julián Villamayor and published by Springer. This book was released on 2019-07-05 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the Sea Surface Temperature (SST) patterns of decadal-to-multidecadal variability observed and simulated by 17 general circulation models (GCMs) are analyzed. Furthermore, their impact on precipitation in West Africa and South America and the atmospheric mechanisms involved are assessed. Through this analysis, the effect of external forcings on these impacts and the relative contribution of decadal-to-multidecadal variability patterns of SST to precipitation are presented in depth. Finally, a humid period in the West African region of the Sahel during the 19th century, previously little documented, is analyzed using an atmospheric GCM. The monsoons of West Africa and South America have shown changes in the timescales of a few decades. Previous work suggests a relationship with patterns of decadal-to-multidecadal variability of SST, such as global warming and the Atlantic and Pacific variability. However, the dynamics underlying this relationship and its simulation by current GCMs had not been addressed in a consistent manner. This is the main motivation of this book. The results of this book not only represent a great step forward in our understanding of the changes in the precipitation regimes of the studied regions, but they can also be of great help for the improvement of decadal prediction systems and the associated social consequences.

This book was released on 2011 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Atmospheric conditions during the dry season of the South American monsoon are instrumental in the initiation of convection during the wet season and are strongly correlated to SSTs within the Atlantic Warm Pool. Subsequently, accurate seasonal prediction of temperature and rainfall during the dry season has the potential to improve our understanding of and the predictability of these variables during future seasons. In this study, we review the fidelity of South American dry season (June-July-August) reforecasts from one global climate model (GCM), and one downscaled regional climate model (RCM). Additionally, we evaluate a second integration of the RCM that uses a bias correction method called anomaly nesting, which is designed to remove the bias of the GCM before the downscaling process is performed. The models are integrated for seven dry seasons (2001-2007), and each season consists of six ensemble members. For this study, we focus on two primary regions: the Amazon River Basin (ARB) and the subtropical region (ST). There are three objectives of this research. The first is to locate regions of model bias for two-meter air temperature and for precipitation within the ARB and the ST using NCEP Climate Forecast System Reanalysis (CFSR) as a comparison dataset.

Download or read book Past Climate Variability in South America and Surrounding Regions written by Francoise Vimeux and published by Springer. This book was released on 2009-09-08 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: South America is a unique place where a number of past climate archives are ava- able from tropical to high latitude regions. It thus offers a unique opportunity to explore past climate variability along a latitudinal transect from the Equator to Polar regions and to study climate teleconnections. Most climate records from tropical and subtropical South America for the past 20,000 years have been interpreted as local responses to shift in the mean position and intensity of the InterTropical Conv- gence Zone due to tropical and extratropical forcings or to changes in the South American Summer Monsoon. Further South, the role of the Southern Hemisphere westerly winds on global climate has been highly investigated with both paleodata and coupled climate models. However the regional response over South America during the last 20,000 years is much more variable from place to place than pre- ously thought. The factors that govern the spatial patterns of variability on millennial scale resolution are still to be understood. The question of past natural rates and ranges of climate conditions over South America is therefore of special relevance in this context since today millions of people live under climates where any changes in monsoon rainfall can lead to catastrophic consequences.

This book was released on 2008-01-29 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally formed around a set of lectures presented at a NATO Advanced Study Institute (ASI), this book has grown to become organised and presented rather more as a textbook than as a standard "collection of proceedings". This therefore is the first unified reference ‘textbook’ in seasonal to interannual climate predictions and their practical uses. Written by some of the world’s leading experts, the book covers a rapidly-developing science of prime social concern.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monsoons supply the majority of annual rainfall to land regions across the tropics and play a prominent role in global climate. Despite this, we lack a complete mechanistic understanding of monsoon characteristics and how they might change with warming. This dissertation draws on theory and a range of climate models to elucidate the physics governing monsoon circulations.First, we investigate the seasonally dependent responses of the South American monsoon to warming. In the latest Geophysical Fluid Dynamics Laboratory Atmospheric Model (AM4), uniform 2-K sea surface temperature warming reduces precipitation by 11%, and precipitation minus evaporation by 40%, in the monsoon onset season, producing a more severe dry season. A column-integrated moist static energy budget analysis helps elucidate the drying mechanism. By comparing the response across seasons we identify two necessary conditions for a region to exhibit a substantial drying response to warming.To better understand the seasonal and global variations in monsoon circulations, Chapter 3 utilizes an idealized modeling framework. We systematically vary the moisture and albedo parameters over an isolated South American continent with reduced heat capacity, but no topography. Irrespective of the local moisture availability, the seasonal cycles of precipitation and circulation over the monsoon sector are distinctly monsoonal with the default surface albedo, but with differing characteristics and dynamical mechanisms. The analysis supports that when the land-ocean thermal contrast is strong enough, inertial instability is sufficient for producing a shallow but vigorous circulation and converging a large amount of moisture from the ocean. Once the land is sufficiently moist, convective instability takes hold and the shallow circulation deepens. Chapter 4 investigates the monsoonal precipitation over a dry continent on synoptic timescales, and provides additional evidence for the importance of inertial instability.In Chapter 5, we utilize an Earth System Model (ESM4.1) to investigate changes in precipitation and aridity over the South American monsoon sector in future emissions scenarios. The projected runoff reductions have implications for energy system planning in Brazil, where 60-80% of monthly power generation comes from hydropower. The possibility of seasonal power generation deficits underscores the importance of climate risk management in the energy sector.

This book was released on 2010-09-08 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: More accurate forecasts of climate conditions over time periods of weeks to a few years could help people plan agricultural activities, mitigate drought, and manage energy resources, amongst other activities; however, current forecast systems have limited ability on these time- scales. Models for such climate forecasts must take into account complex interactions among the ocean, atmosphere, and land surface. Such processes can be difficult to represent realistically. To improve the quality of forecasts, this book makes recommendations about the development of the tools used in forecasting and about specific research goals for improving understanding of sources of predictability. To improve the accessibility of these forecasts to decision-makers and researchers, this book also suggests best practices to improve how forecasts are made and disseminated.
