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 2018 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sahel is the semiaridWest African region between the Sahara desert andthe wet tropical savanna. The Sahel rainfall depends on the West AfricanMonsoon (WAM) system and peaks between July and September. The rainfallregimes of the Amazonia and Northeast regions, located in northernBrazil, depend on the South American Monsoon system. The Amazonia isthe region covered by the Amazon River basin, where heavy rains occurthroughout the year but with a rainier season extending from December toMay. The Northeast is a semiarid region with a short rainy season betweenMarch and May.Precipitation regimes in these three regions have undergone changes overtime with important humanitarian, environmental and economic consequencesand have been a major topic of study (e.g. Rodríguez-Fonseca et al., 2015;Zhou and Lau, 2001; Marengo et al., 2016). At decadal-to-multidecadal timescales, these changes have been mainly associated with the global sea surfacetemperature (SST) variability. Particularly, the Sahel precipitation hasbeen associated with the global warming (GW), the Atlantic MultidecadalVariability (AMV) and the Interdecadal Pacific Oscillation (IPO) modes ofdecadal-to-multidecadal SST variability (e.g. Mohino et al., 2011a). The Amazoniaand Northeast rainfall changes have been related to the Pacific and theAtlantic SST variability at decadal time scales (e.g. Grimm and Saboia, 2015),which is led by the AMV and IPO...
Download or read book Interdecadal Changes in Ocean Teleconnections with the Sahel written by Roberto Suárez Moreno and published by Springer. This book was released on 2018-11-27 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: In tropical latitudes, monsoons trigger regimes of strong seasonal rainfall over the continents. Over the West African region, the rainfall has shown a strong variability from interannual to decadal time scales. The atmospheric response to global sea surface temperatures is the leading cause of rainfall variability in the West African Sahel. This thesis explores changes in the leading ocean forcing of Sahelian rainfall interannual variability. It anaylzes the dynamical mechanisms at work to explain the non-stationary sea surface temperature-forced response of anomalous rainfall. The underlying multidecadal sea surface temperature background is raised as a key factor that favors some interannual teleconnections and inhibits others. Results of this thesis are relevant for improving the seasonal predictability of summer rainfall in the Sahel.

Download or read book Wet and Dry Periods in Regions Surrounding the Atlantic Ocean Basin written by Anita Drumond and published by Frontiers Media SA. This book was released on 2016-05-20 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atlantic Ocean is the second-largest of the world's oceanic divisions. It is bounded by the continents of America, Europe and Africa and at its pole wards margins by the Arctic and the Southern Oceans. Different climatic patterns can be observed along its large latitudinal domain, which extends from the equator to sub-polar regions. Thus, different tropical and extra-tropical meteorological systems may have some influence on the characterization of precipitation regimes observed surrounding the basin, such as the Intertropical Convergence Zone (ITCZ), tropical monsoon systems, westerly storm tracks and atmospheric rivers. The subtropical regions of the Azores and South Atlantic high pressure systems are large evaporative areas which act as important moisture sources for the adjacent continents. Variations in the oceanic characteristics may influence the moisture transport towards the neighboring landmasses and alter the precipitation. The influence of climatic variability modes manifest not only over the Atlantic Ocean, but also over other oceanic regions, may also interact with the regional hydrological budget, thereby generating long periods of drought or excessive precipitation over the Atlantic rim landmasses. This Research Topic intends to highlight the advances of the scientific community in investigating the continental precipitation surrounding the Atlantic Ocean and its variability on various temporal and spatial scales.

Download or read book Tropical Climatology written by Glenn R. McGregor and published by John Wiley & Sons. This book was released on 1998-04-22 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical Climatology Second Edition Glenn R. McGregor, The University of Birmingham, UK Simon Nieuwolt (deceased) Formerly Adjunct Professor, University of Guelph, Canada Climatology, the scientific study of climate, is not only concerned with explaining why a location's or region's climate is like it is but also with describing the nature and availability of the climate resource for a wide range of human activities. This subject is of great relevance to the tropics as climate in many ways controls the lives and economic activities of the approximately 2400 million people living in tropical regions. Tropical climates also have effects that reach far beyond the limits of the regions where they actually prevail: the global general circulation is largely driven by the export of considerable amounts of heat energy from tropical to extratropical latitudes: a large part of all atmospheric water content originates from the tropics, and intermittent tropical phenomena, like El Nino Southern Oscillation (ENSO), not only influence the climates over extensive tropical areas but many parts of the extratropics. The climate sensitivity of populations and economic production in the tropics also makes these regions especially vulnerable to any negative impacts arising from human-induced climate change. Tropical Climatology aims to provide a geographical viewpoint on the physical processes in the tropical atmosphere: to offer explanations of how a location's climate is a product of these processes and to highlight the implications of tropical atmospheric behaviour and climate change for those living in the tropics. This is the second edition of the book and reflects the substantial developments in the field of tropical climatology which have taken place over the two decades since the publication of the first edition. New and updated material has been included on the nature of the general tropical circulation, the monsoons, the quasi-biennial oscillation, the 40-50 day tropical circulation, the El Nino Southern Oscillation phenomenon and its climatic impacts, tropical disturbances, the characteristics of regional tropical climates and climate change in the tropics. The readership of the book remains essentially the same as that for which the first edition was intended; second to third year students in geography and the environmental sciences who have some background in climatology. The updated reference list will, however, provide an entry point for non-specialist postgraduates into the field of tropical climatology.

Download or read book The Global Monsoon System written by Chih-Pei Chang and published by World Scientific. This book was released on 2011 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a current review of the science of monsoon research and forecasting. The contents are based on the invited reviews presented at the World Meteorological Organization's Fourth International Workshop on Monsoons in late 2008, with subsequent manuscripts revised from 2009 to early 2010. The book builds on the concept that the monsoons in various parts of the globe can be viewed as components of an integrated global monsoon system, while emphasizing that significant region-specific characteristics are present in individual monsoon regions. The topics covered include all major monsoon regions and time scales (mesoscale, synoptic, intraseasonal, interannual, decadal, and climate change). It is intended to provide an updated comprehensive review of the current status of knowledge, modeling capability, and future directions in the research of monsoon systems around the world.
Download or read book The Indian Ocean and its Role in the Global Climate System written by Caroline C. Ummenhofer and published by Elsevier. This book was released on 2024-04-18 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Indian Ocean and its Role in the Global Climate System provides an overview of our contemporary understanding of the Indian Ocean (geology, atmosphere, ocean, hydrology, biogeochemistry) and its role in the climate system. It describes the monsoon systems, Indian Ocean circulation and connections with other ocean basins. Climatic phenomena in the Indian Ocean are detailed across a range of timescales (seasonal, interannual to multi-decadal). Biogeochemical and ecosystem variability is also described. The book will provide a summary of different tools (e.g., observations, modeling, paleoclimate records) that are used for understanding Indian Ocean variability and trends. Recent trends and future projections of the Indian Ocean, including warming, extreme events, ocean acidification and deoxygenation will be detailed. The Indian Ocean is unique and different from other tropical ocean basins due to its geography. It is traditionally under-observed and understudied, yet plays a fundamental role for regional and global climate. The vagaries of the Asian monsoon affect over a billion people and a third of the global population live in the vicinity of the Indian Ocean. It is also particularly vulnerable to climate change, with robust warming and trends in heat and freshwater observed in recent decades. Advances have recently been made in our understanding of the Indian Ocean's circulation, interactions with adjacent ocean basins, and its role in regional and global climate. Nonetheless, significant gaps remain in understanding, observing, modeling, and predicting Indian Ocean variability and change across a range of timescales. As such, this book is the perfect compendium to any researcher, student, teacher/lecturer in the fields of oceanography, atmospheric science, paleoclimate, environmental science, meteorology and geology, as well as policy managers and water resource managers. - Provides interdisciplinary content with a comprehensive overview for students and practitioners from a wide range of disciplines as well as for stakeholders - Presents a broad overview and background on the current state of knowledge of the variability, change, and regional impacts of the Indian Ocean - Includes links to animations, slideshows, and other educational resources

Available in PDF, EPUB and Kindle. Book excerpt: Climate change is emerging as one of the most important issues of our time, with the potential to cause profound cascading effects on ecosystems and society. However, these effects are poorly understood and our projections for climate change trends and effects have thus far proven to be inaccurate. In this collection of 24 chapters, we present a cross-section of some of the most challenging issues related to oceans, lakes, forests, and agricultural systems under a changing climate. The authors present evidence for changes and variability in climatic and atmospheric conditions, investigate some the impacts that climate change is having on the Earth's ecological and social systems, and provide novel ideas, advances and applications for mitigation and adaptation of our socio-ecological systems to climate change. Difficult questions are asked. What have been some of the impacts of climate change on our natural and managed ecosystems? How do we manage for resilient socio-ecological systems? How do we predict the future? What are relevant climatic change and management scenarios? How can we shape management regimes to increase our adaptive capacity to climate change? These themes are visited across broad spatial and temporal scales, touch on important and relevant ecological patterns and processes, and represent broad geographic regions, from the tropics, to temperate and boreal regions, to the Arctic.
