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.

Описание: Covering the years of Japanese invasion during World War II from 1937 to 1945, this essay collection recounts Chinese experiences of living and working under conditions of war. Each of the regimes that ruled a divided China—occupation governments, Chinese Nationalists, and Chinese Communists—demanded and glorified the full commitment of the people and their resources in the prosecution of war. Through stories of both everyday people and mid-level technocrats charged with carrying out the war, this book brings to light the enormous gap between the leadership’s demands and the reality of everyday life. Eight long years of war exposed the unrealistic nature of elite demands for unreserved commitment. As the political leaders faced numerous obstacles in material mobilization and retreated to rhetoric of spiritual resistance, the Chinese populace resorted to localized strategies ranging from stoic adaptation to cynical profiteering, articulated variously with touches of humor and tragedy. These localized strategies are examined through stories of people at varying classes and levels of involvement in living, working, and trying to work through the war under the different regimes. In less than a decade, millions of Chinese were subjects of disciplinary regimes that dictated the celebration of holidays, the films available for viewing, the stories told in tea houses, and the restrictions governing the daily operations and participants of businesses—thus impacting the people of China for years to come. This volume looks at the narratives of those affected by the war and regimes to understand perspectives of both sides of the war and its total outcomes. Living and Working in Wartime China depicts the brutal micromanaging of ordinary lives, devoid of compelling national purposes, that both undercut the regimes’ relationships with their people and helped establish the managerial infrastructure of authoritarian regimes in subsequent postwar years.
Описание: From the ancient origins of the proboscideans to the present-day crisis of the living elephants, this volume synthesizes the behavior, ecology and conservation of elephants, while covering also the history of human interactions with elephants, all within the theoretical framework of evolutionary biology. The book begins with a survey of the 60-million year evolutionary history of the proboscideans emphasizing the role of climate and vegetation change in giving rise to a bewildering array of species, but also discussing the possible role of humans in the late Pleistocene extinction of mastodons and mammoths. The latest information on the molecular genetics of African and Asian elephants and its taxonomic implications are then presented. The rise of the elephant culture in Asia, and its early demise in Africa are traced along with an original interpretation of this unique animal-human relationship. The book then moves on to the social life of elephants as it relates to reproductive strategies of males and females, development of behavior in young, communication, ranging patterns, and societal organization. The foraging strategies of elephants, their impact on the vegetation and landscape are then discussed. The dynamics of elephant populations in relation to hunting for ivory and their population viability are described with the aid of mathematical models. A detailed account of elephant-human interactions includes a treatment of crop depredation by elephants in relation to their natural ecology, manslaughter by elephants, habitat manipulation by humans, and a history of the ivory trade and poaching in the two continents. The ecological information is brought together in the final chapter to formulate a set of pragmatic recommendationor the long-term conservation of elephants. The broadest treatment of the subject yet undertaken, by one of the leading workers in the field, Raman Sukumar, the book promises to bring the understanding of elephants to a new level. It should be of interest not only to biologists but also a broader audience including field ecologists, wildlife administrators, historians, conservationists and all those interested in elephants and their future.
