Sst Anomalies

Abstract An atmospheric general circulation model (AGCM) is used to examine the role of Indian Ocean sea surface temperature (SST) anomalies in regional climate variability. In particular, the authors focus on the effect of the basinwide warming that occurs during December through May after the mature phase of El Niño. To elucidate the relative importance of local and remote forcing, model solutions were sought for experiments where SST anomalies are inserted in the (i) tropical Indo-Pacific Oceans, (ii) tropical Pacific Ocean, and (iii) tropical Indian Ocean. A 10-member ensemble simulation is carried out for each of the three forcing scenarios. The model solutions demonstrate that precipitation variations over the southwest Indian Ocean are tied to local SST anomalies and are highly reproducible. Changes in the Indian Ocean–Walker circulation suppress precipitation over the tropical west Pacific–Maritime Continent, contributing to the development of a low-level anticyclone over the Philippine and South China Seas. Our model results indicate that more than 50% of the total precipitation anomalies over the tropical west Pacific–Maritime Continent is forced by remote Indian Ocean SST anomalies, offering an additional mechanism for the Philippine Sea anticyclone apart from Pacific SST. This anticyclone increases precipitation along the East Asian winter monsoon front from December to May. The anomalous subsidence over the Maritime Continent in conjunction with persistent anomalies of SST and precipitation over the Indian Ocean in spring prevent the northwestward migration of the ITCZ and the associated deep moist layer, causing a significant delay in the Indian summer monsoon onset in June by 6–7 days. At time scales of 5 days, however, the reproducibility of the northward progression of the ITCZ during the onset is low. Results indicate that Indian Ocean SST anomalies during December through May that develop in response to both atmospheric and oceanic processes to El Niño need to be considered for a complete understanding of regional climate variability, particularly around the Indian Ocean rim.

The Individual

In this paper we investigate how well residents of the Andaman coast in Phang Nga province, Thailand, are prepared for earthquakes and tsunami. It is hypothesized that formal education can promote disaster preparedness because education enhances individual cognitive and learning skills, as well as access to information. A survey was conducted of 557 households in the areas that received tsunami warnings following the Indian Ocean earthquakes on 11 April 2012. Interviews were carried out during the period of numerous aftershocks, which put residents in the region on high alert. The respondents were asked what emergency preparedness measures they had taken following the 11 April earthquakes. Using the partial proportional odds model, the paper investigates determinants of personal disaster preparedness measured as the number of preparedness actions taken. Controlling for village effects, we find that formal education, measured at the individual, household, and community levels, has a positive relationship with taking preparedness measures. For the survey group without past disaster experience, the education level of household members is positively related to disaster preparedness. The findings also show that disaster related training is most effective for individuals with high educational attainment. Furthermore, living in a community with a higher proportion of women who have at least a secondary education increases the likelihood of disaster preparedness. In conclusion, we found that formal education can increase disaster preparedness and reduce vulnerability to natural hazards.

Until fairly recently, histories of European imperial expansion in the Indian Ocean region have been written largely in terms of the endeavours of Europeans in creating and controlling empire. Only in the last couple of decades has recognition been given slowly to the role of the indigenous economic and political compradors, both large and small, who were vital to the evolution and sustenance of European colonial empires.

This chapter considers the role of family networks, both French and Tamil, in the development of French empire in India. It charts how two Tamil dynasties drew on their kinship ties to create commercial networks that spanned the Indian Ocean, and highlights the involvement of of one local woman in the relationship between French colonists and local familial institutions.

The Relationship

This chapter provides a historical overview of ambivalent encounters between Indonesia and the Arab world through findings that show the relationship between Indonesia and the Middle East. It recounts the Indonesians' earliest encounters with Arab traders in the seventh century, from confrontations with Indo Persian Sufi up to the current democratization process that have been marked by contradictory dynamics. It also explains how Arabs have been acknowledged as teachers of Islam and allies in the postcolonial nonbloc movement. The chapter describes the gloomy counterimage of the Arab world against which Indonesian officials and religious leaders drew the picture of a tolerant, pluralist Indonesian Islam. It mentions the key role of the mobility across the Indian Ocean in the formation of Islamic culture in Indonesia.

Western Scholarship

AbstractThis preface introduces the five essays that comprise this special issue of JESHO. The author provides a synoptic overview of western scholarship on the Indian Ocean and on trade diasporas in order to situate the papers. This scholarship has only recently begun to recognize the important role of the Indian Ocean in early modern history, a change that the author traces to the work of K.N. Chaudhuri, Janet Abu-Lughod, and Philip Curtin. He concludes that the five papers in this special issue collectively mark an important step forward in the historiography of the Indian Ocean. Les cinq articles qui font partie du numéro du JESHO sont précedés d'une préface ou l'auteur donne une vue d'ensemble du travail scientifique occidental qui parle de l'océan Indien et des diasporas mercantiles. D'après l'auteur, le role capital de l'océan Indien au début de l'époque moderne commence à être mieux connu grace aux publications de K.N. Chaudhuri, de Janet Abu-Lughod et de Philip Curtin. Les cinq articles ci-compris représentent, donc, un pas en avant pour l'historiographie de l'océan Indien, selon cet auteur.

AbstractThe role of commodities from the Indian Ocean is at the centre of this study of Roman imperial worldviews (c. 1st to 6th century). It begins by surveying the various kinds of objects brought to the Mediterranean from South Asia, e.g. spices and fabrics, and their routes, and then examines the ways in which Romans thought about them, both moralising and more strictly economic. This affords the chance to assess the notion of the exotic in Roman culture. Le rôle des marchandises venant de l'Océan Indien se retrouve au centre de cette étude des visions romaines impériales du monde (1er au 6e siècles). Ce travail commence par une étude générale des objets variés importés à la région méditerranéenne de l'Asie du Sud, par exemple des épices et des tissus, et de leurs itinéraires, et examine par la suite ce que les Romains peuvent en avoir pensé du point de vue moralisant et plus strictement économique. Ceci permet d'évaluer la notion de l'exotisme dans la culture romaine.
