Indian Ocean Tropical Cyclones And Climate Change

Tropical cyclones are topic that is not appropriately known to the public at large, but climate change has been on the public’s mind since the last decade and a concern that has peaked in the new millennium. Like the television programs of Jean Yves Cousteau the ‘plight of the oceans’, have recent documentaries nurtured a conscio- ness that major climatological changes are in the offing, even have started to develop. The retreat of glaciers on mountain tops and in Polar Regions is ‘being seen’ on ‘the small screen’ and has favored an environmental awareness in all populations that are enjoying an average well-being on Planet Earth. The vivid images on screen of storms, floods, and tsunamis share the fear provoking landscapes of deforestation, desertification and the like. Watching such as this one is seen are voices warning of what over is ‘in store’ if the causative problems are not remedied. Talking and d- cussing are useful, but action must follow. Understanding the full ramifications of climate change on tropical cyclones is a task that will takes several decades. In Climate Change 2007, the Fourth Assessment Report of the United Nations Intergovernmental Panel on Climate Change (IPCC) a high probability of major changes in tropical cyclone activity across the various ocean basins is highlighted.

This book deals with recent advances in our understanding and prediction of tropical cyclogenesis, intensification and movement as well as landfall processes like heavy rainfall, gale wind and storm surge based on the latest observational and numerical weather prediction (NWP) modeling platforms. It also includes tropical cyclone (TC) management issues like early warning systems, recent high impact TC events, disaster preparedness, assessment of risk and vulnerability including construction, archiving and retrieval of the best tracking and historical data sets, policy decision etc., in view of recent findings on climate change aspects and their impact on TC activity. The chapters are authored by leading experts, both from research and operational environments. This book is relevant to cyclone forecasters and researchers, managers, policy makers, graduate and undergraduate students. It intends to stimulate thinking and hence further research in the field of TCs and climate change, especially over the Indian Ocean region and provides high-quality reference materials for all the users mentioned above for the management of TCs over this region.

Essay from the year 2011 in the subject Geography / Earth Science - Meteorology, Aeronomy, Climatology, grade: 11.0, University of Exeter, language: English, abstract: Since tropical cyclones(TCs) are one of the major geophysical cause of loss of life and property, it is important to understand if there is any change in the frequency and intensity of TCs due to anthropogenic climate change. IPCC considers 0.25-0.5 C increase in warming over tropical oceans over the past few decades due to increase in greenhouse gas concentration over past 50years. During 6th International Workshop on Tropical Cyclones, a statement was released on the connection between the TCs and anthropogenic climate change. The statement was in response to the increase in number of recent high-impact TC events which includes, 10 land falling Tcs in Japan in 2004, 5 TCs affecting the Cook island in a five week period during 2005, cyclone Gafilo in Madagascar in 2004, cyclone Larry in Australia in 2006, typhoon Saomai in China in 2006, and violently active Atlantic TC season during the period of 2004 to 2005, including the catastrophic socioeconomic impact of Hurricane Katrina. A few recent articles [1] have noted a large increase in TC’s intensity, frequency and wind-speeds in some regions during past 5 decades, which could be attributed to the increase in the concentration of green house gases in past 50years. However, other studies explain this noticed increase as a result of better observations made and instruments used, making it easier to detect TCs. Consensus statement by the International workshop on TC-6 reported uncertain conclusions about the influence of climate change on TC after taking into account evidence both for and against. It was concluded that no TC could be solely attributed to the anthropogenic climate change. Model and theory predicts 3-5% increase in wind speed per degree C increase in SST. But, there is inconsistency between the small change in wind speed projected by theory and modelling versus large variations reported by some observational studies. Significant limitation of measurements over some regions make detection of trends difficult. It was suggested that if increase in SST continues, susceptibility to TC storm surge flooding would strengthen.

A comprehensive guide to managing and mitigating natural disasters Recent years have seen a surge in the number, frequency, and severity of natural disasters, with further increases expected as the climate continues to change. However, advanced computational and geospatial technologies have enabled the development of sophisticated early warning systems and techniques to predict, manage, and mitigate disasters.Techniques for Disaster Risk Management and Mitigation explores different approaches to forecasting disasters and provides guidance on mitigation and adaptation strategies. Volume highlights include: Review of current and emerging technologies for disaster prediction Different approaches to risk management and mitigation Strategies for implementing disaster plans and infrastructure improvements Guidance on integrating artificial intelligence with GIS and earth observation data Examination of the regional and global impacts of disasters under climate variability

This open access book discusses the impact of human-induced global climate change on the regional climate and monsoons of the Indian subcontinent, adjoining Indian Ocean and the Himalayas. It documents the regional climate change projections based on the climate models used in the IPCC Fifth Assessment Report (AR5) and climate change modeling studies using the IITM Earth System Model (ESM) and CORDEX South Asia datasets. The IPCC assessment reports, published every 6–7 years, constitute important reference materials for major policy decisions on climate change, adaptation, and mitigation. While the IPCC assessment reports largely provide a global perspective on climate change, the focus on regional climate change aspects is considerably limited. The effects of climate change over the Indian subcontinent involve complex physical processes on different space and time scales, especially given that the mean climate of this region is generally shaped by the Indian monsoon and the unique high-elevation geographical features such as the Himalayas, the Western Ghats, the Tibetan Plateau and the adjoining Indian Ocean, Arabian Sea, and Bay of Bengal. This book also presents policy relevant information based on robust scientific analysis and assessments of the observed and projected future climate change over the Indian region.

This book deals primarily with understanding, monitoring and prediction of Tropical Cyclones (TCs) over the North Indian Ocean (NIO). There is special emphasis on TC genesis, intensification, movement and associated adverse weather like heavy rainfall and gale winds. It highlights the current state of research on TCs over the NIO and recent improvements in early warning systems due to advances in observational, analytical and numerical weather prediction techniques. The chapters in the book are authored by leading experts from research and operational environments.The chapters presented in the book intend to stimulate thinking and hence further research in the field of TCs, especially over the NIO region. They provide high quality reference material for all experts working in the field of TC related disaster management. This book is relevant to TC forecasters and researchers, managers, policy makers, graduate and undergraduate students.

The subject of tropical cyclones in Southern Africa, also known as hurricanes or typhoons in other regions of the world, has been growing over the past few decades. However, there is still limited literature on foundational and fundamental topics on the matter. To this end, this book addresses this gap, citing some examples from both historic and recent tropical cyclones. The book presents meteorological and climatic aspects of tropical cyclones, including reviews on forecasting, warning message dissemination and public response aspects of early warning systems with a focus on the Tropical Cyclones Idai and Kenneth. Fundamentals in disaster risk reduction (DRR) are also discussed moving from the provisions of the Hyogo Framework for Action (2005–2015), to the Sendai Framework for Disaster Risk Reduction (2015–2030). Climate change issues are central to the publication, as well as the role of information and communication technologies in DRR and management. The book also tackles some challenges and opportunities associated with the implementation of regional legal and institutional frameworks on DRR. The book comes as part of a series with three volumes. The other volumes include “Cyclones in Southern Africa Vol. 1: Interfacing the Catastrophic Impact of Cyclone Idai with SDGs in Zimbabwe” and “Cyclones in Southern Africa Vol 3: Implications for the Sustainable Development Goals”. To this end, this book is suitable as a read for several professionals and disciplines such as tourism and hospitality studies, economics, sustainable development, development studies, environmental sciences, arts, geography, life sciences, politics, planning and public health.
