Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of a Symposium held at the University of Kiel, Germany, from 31 March to 6 April, 1971. The Symposium was organized by the Scientific Committee on Oceanic Research (SCOR) and the Marine Productivity section of the International Biological Programme (IBPIPM) with the assistance of the United Nations Educational, Scientific and Cultural Organization (UNESCO), the Food and Agriculture Organization (FAO), and the International Association of Biological Oceanography (IABO). The aim of the Symposium was to summarize present knowledge of the biology of the Indian Ocean. Twenty-two presentations by invited speakers reviewed the research work carried out during the International Indian Ocean Expedition (lIOE) 1959 -1965, the first cooperative project coordinated by the Intergovernmental Oceanographic Commission (IOC). In addition, reports were presented of postexpedition examination of material and of more recent investigations relevant to the aims of the lIOE. In keeping with the aims of "Ecological Studies", the present volume contains much new information and some synthesis, all directed towards obtaining an understanding of the functioning and organization of the ecosystem of the Indian Ocean. The plan of the Symposium was to present the relevant meteorological, physical, chemical and geological background and to follow this with the various aspects of biological oceanography. Because of the uneven stage of development of the different disciplines, the papers included in this volume vary in their analytical level.

Download or read book Climate and circulation of the tropics written by S. Hastenrath and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical atmosphere and ocean are receiving increased attention in relation to the functioning of the global climate system, the remarkable climatic variability in low latitudes, and the associated manifold environmental and societal consequences. Beyond the traditional emphasis of meteor ology on weather analysis and forecasting, there is a growing interest in the climate and large scale circulation of the tropics. This book may serve as a text for graduate and upper-division undergraduate students in meteorology, and is also intended as a reference work for practicing meteorologists, and researchers in the atmospheric, oceanic, and other environmental sciences. I began writing this book in 1979, but the roots reach further back. Early experiences in North Africa fuelled my curiosity about the low latitudes. In 1960 I seized the opportunity to work in the National Meteorological Service of El Salvador in Central America. My interest in the tropics continued after joining the University of Wisconsin in 1963. Field research brought me to the equatorial Pacific, and many times to the tropical Americas and Africa. This involved visits and correspondence with many weather services. My acquaintance with Australasia and South Asia is limited to short study visits, but includes continuous contacts with colleagues at key research institutions in India, namely the India Meteorological Department, the Indian Institute of Tropical Meteorology, and Andhra University. A guest semester at the University of the Witwatersrand in 1971 and related travels provided a perspective on the problems of Southern Africa.

Available in PDF, EPUB and Kindle. Book excerpt: This study focuses on the zonal weakening, eastern termination and seasonal variations of the Atlantic equatorial undercurrent (EUC). The main and most original contribution of the dissertation is a detailed analysis of the Atlantic EUC simulated by Philander and Pacanowski's (1986)general circulation model (GCM), which provides a novel description of the dynamical regimes governing various regions of a nonlinear stratified undercurrent. Only in a narrow deep western region of the simulation does one find an approximately inertial regime corresponding to zonal acceleration. Elsewhere frictional processes cannot be ignored. The bulk of the mid-basin model EUC terminates in the overlying westward surface flow while only a small fraction (the deeper more inertial layers) terminates at the eastern coast. In agreement with observations, a robust feature of the GCM not present in simpler models is the apparent migration of the EUC core from above the thermocline in the west to below it in the east. In the GCM, this happens because the eastward flow is eroded more efficiently by vertical friction above the base of the thermocline than by lateral friction at greater depths. This mechanism is a plausible one for the observed EUC. A scale analysis using a depth scale which decreases with distance eastwards predicts the model zonal transition between western inertial and eastern inertio-frictional regimes. Historical and recent observations and simple models of the equatorial and coastal eastern undercurrents are reviewed, and a new analysis of current measurements in the eastern equatorial Atlantic is presented. Although the measurements are inadequate for definitive conclusions, they suggest that Lukas' (1981) claim of a spring surge of the Pacific EUC to the eastern coast and a seasonal branching of the EUC into a coastal southeastward undercurrent may also hold for the Atlantic Ocean. To improve the agreement between observed and modelled strength of the eastern undercurrent, it is suggested that the eddy coefficient of horizontal mixing should be reduced in future GCM simulations.

Available in PDF, EPUB and Kindle. Book excerpt: The first edition of my book "Climate and Circulation of the Tropics" was reasonably up to date to the middle of 1985. In a second printing in 1988 it was possible to complete a few literature references and to correct some misprints. However, vigorous research has taken place over the past five years in various areas of tropical climate dynamics, especially in the atmosphere-ocean mechanisms of climate anomalies, climate prediction, ocean circulation, and paleoclimates. Promising progress has also been made in the application of general circulation modelling to tropical climate problems. In the present second edition, named "Climate Dynamics of the Tropics", I have attempted to incorporate much of the recent work to late 1990. Chapters 8 and 9 have been essentially re-written, and major additions have been made to Chapters 4 and 12 in particular. I would like to acknowledge the continued support by the U.S. National Science Foundation over the past five years. B. Parthasarathy, Poona, and H. Lessmann, San Salvador, sent me updates of data series not easily accessible. I have benefitted from discussions with numerous colleagues in the United States and overseas. In the preparation of this second edition, Marilyn Wolff patiently transferred my illegible hand-written drafts onto word processor. Dierk Polzin and Dan Skemp assisted me with the creation of the page masters and the subject index and Christopher Collimore with the author index.

This book was released on 1981 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The changes occurring in the temperature field in the Somali Basin and off the Arabian coast have been monitored from October 1975 through December 1979 by a time series of temperature sections obtained along the tanker sea lane offshore between 2 S and 22 N. The development and decay of the large eddy (up to roughly 600 km in diameter) in the northern Somali Basin and its smaller associated eddies were observed each southwest monsoon. Strong horizontal thermal gradients particularly in the upper 200 m occur at the eddy boundaries, and currents in this region can attain velocities of up to 7 knots. Monthly wind stress contoured for the western Indian Ocean clearly shows the southwest monsoon from May through September (with values over 4 dynes/sq. cm during July) to be considerably stronger than the northeast monsoon with a maximum in January. Maps of wind stress curl during the southwest monsoon show a large region of negative curl (over -4 x 10 to the-8th dynes/cc) to the northeast off the somali coast, whereas a region of a high positive curl occurs off the Arabian peninsula and in a small band off the Somali east coast north of 5 N. Sverdrup mass transports of up to 40 x 10 to the -12th g/sec to the north off the Somali coast are in rough agreement with observed values. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The International Indian Ocean Expedition (1960-65) has for the first time provided a sufficiently complete data set to support an investigation of the oceanographic and climatic seasonal influence on Indian Ocean thermal structure in the upper 500 m and north of 40 degrees S lat. Analysis of 23,847 bathythermograph and Nansen Cast measurements form the basis for a division of the Indian Ocean into 32 separate Primary Areas with distinct thermal features. The basic thermal parameters considered in the analysis and depicted graphically in this report include mixed-layer depth, maximum thermal gradient, five parameters of the permanent thermocline, and 2C-interval isotherm depths to 500 m. The thermal structure within each oceanographic region is qualitatively evaluated in terms of the relative effects of net surface heat exchange, heat advection, and circulation dynamics. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Equatorial ocean dynamics are investigated using analytical and simple numerical models. The steady circulation is first examined using a linear equatorial beta-plane formulation in which continuous density stratification is a key element. The basin is horizontally unbounded and forced by either winds or a surface temperature boundary condition. Two vertically diffusive models are proposed to examine the effects of different turbulence parameterizations. One is characterized by temperature dissipation proportional to temperature itself, the other has biharmonic friction proportional to a fourth derivative of velocity. Both lead to equations for the steady state that are in many ways analogous to the well-known equations governing equatorial wave motion. The analogies are exploited both in obtaining analytical solutions and in describing the flow dynamics.
