"Variability of Coastal Current" is a comprehensive book written by D Soum, which provides an in-depth analysis of the coastal current and its variability. The book covers various aspects of oceanography, including the continental slope and shelf, thermocline, and water masses. The author examines the influence of monsoon winds on the coastal currents, eddies, upwelling, and water properties such as temperature and salinity. The book explores the dynamics of the coastal current and its circulation within the Arabian Sea, Bay of Bengal, and the Indian Ocean. The author describes the physical processes, mesoscale and submesoscale features, and the impact of coastal upwelling, cyclonic, and anticyclonic eddies on the current. The book also discusses the use of remote sensing and satellite observations in studying the variability of the current and the seasonal changes. The author highlights the importance of understanding the variability of the Bay of Bengal coastal current in the coastal zone and its impact on sea level, winds, currents, and tides. The book also draws comparisons with other eastern boundary currents such as the Benguela Current, Brazil Current, California Current, Canary Current, Somali Current, Leeuwin Current, and Agulhas Current. Overall, "Variability of Coastal Current" provides a comprehensive overview of the variability of the Bay of Bengal coastal current and its significance in oceanography. The book is an excellent resource for researchers, students, and professionals interested in coastal oceanography and the dynamics of eastern boundary currents.
