Availability of these data has opened up a new possibility to examine the impact of these data in the operational NWP system of India Meteorological Department (IMD). In this paper, impact of KALPANA-1 CMV  data in the  NWP  system  of IMD has been presented based on the experiments carried-out for the monsoon 2003.  The impact of additional wind data in the model is found to be significant and beneficial.

The Impact

The Indian Ocean Region (IOR) has become one of the main economic forces globally, and countries within the IOR have attempted to promote their intra-regional trade. This study investigates the spatiotemporal evolution of the community structures of the intra-regional trade and the impact of determinant factors on the formation of trade community structures of the IOR from 1996 to 2017 using the methods of social network analysis. Trade communities are groups of countries with measurably denser intra-trade ties but with extra-trade ties that are measurably sparser among different communities. The results show that the extent of trade integration and the trade community structures of the IOR changed from strengthening between 1996 and 2014 to weakening between 2015 and 2017. The largest explanatory power of the formation of the IOR trade community structures was the IOR countries’ economic size, indicating that market remained the strongest driver. The second-largest explanatory power was geographical proximity, suggesting that countries within the IOR engaged in intra-regional trade still tended to select geographically proximate trading partners. The third- and the fourth-largest were common civilization and regional organizational memberships, respectively. This indicates that sharing a common civilization and constructing intra-regional institutional arrangements (especially open trade policies) helped the countries within the IOR strengthen their trade communities.

Cultural Interactions

AbstractThis article examines the consequences of the Ming maritime expeditions led by Admiral Zheng He (1371–1433) in the early fifteenth century on Indian Ocean diplomacy, trade, and cross-cultural interactions. The presence of the powerful Ming navy not only introduced an unprecedented militaristic aspect to the Indian Ocean region, but also led to the emergence of state-directed commercial activity in the maritime world that extended from Ming China to the Swahili coast of Africa. Additionally, these expeditions stimulated the movement of people and animals across the oceanic space and might eventually have facilitated the rapid entry of European commercial enterprises into the Indian Ocean region during the second half of the fifteenth century.

The Asymmetry

This chapter examines Indian and Chinese perspectives of each other as major powers and their respective roles in the Indian Ocean. It focuses on the following elements: (a) China’s strategic imperatives in the Indian Ocean Region, (b) India’s views on its special role in the Indian Ocean and the legitimacy of the presence of other powers, (c) China’s strategic vulnerabilities in the Indian Ocean and India’s wish to leverage those vulnerabilities, (d) the asymmetry in Indian and Chinese threat perceptions, and (d) Chinese perspectives of the status of India in the international system and India’s claims to a special role in the Indian Ocean. The chapter concludes that even if China were to take a more transparent approach to its activities, significant differences in perceptions of threat and over status and legitimacy will produce a highly competitive dynamic between them in the maritime domain.

The conference was sponsored by the African Research Committee and was held at the Minnowbrook Conference Center of Syracuse University from October 30 to November 2, 1965. The disciplines represented were social and cultural anthropology, musicology, sociology, social psychology, political science, and history. Participants included Philip Allen (Department of State); Frederick Burke (Syracuse University); Remi Clignet (Northwestern University); L. Gray Cowan (Columbia University); Norma McCloud (Tulane University); John Middleton (Northwestern University); Allen Rawick (Library of Congress); Aidan Southall, Chairman (Syracuse University); and Peter Wilson (Yale University). The conference concentrated its efforts on seeking and sharing a common understanding of the social background of the diverse ocean and island region that includes Madagascar, the Comoros, Mauritius, Réunion, and the Seychelles and on exploring precisely the extent to which linked interdisciplinary and comparative studies would be fruitful. The conference came to a strong and unanimous conclusion that the Western Indian Ocean Region offers the challenging possiblity of a real breakthrough in a number of dissimilar but closely interlocking research interests. The main recommendations of the conference are as follows: 1. That a rather informal clearinghouse should be established which would institute and maintain contact between social scientists interested in the region and keep them up to date on all relevant plans and work in progress. 2. That a careful and detailed application should be drawn up to obtain funds for carrying out a series of well-balanced and integrated studies, attracting graduate students and training them for further work, securing library resources, and forming appropriate ties with interested scholars and academic institutions overseas.
