The book is about climate change and tropical cyclones, with an emphasis on the Indian Ocean. It highlights a probability of major changes in tropical cyclone activity across the various ocean basins. The Indian Ocean including the Arabian Sea and the Bay of Bengal are of particular concern because of the high population density along their coastlines. The book aims to reveal the scientific bases of the extreme events and the complexities inherent in combating their hazardous impact. The chapters are authored by leading experts, both from research and operational meteorological environments. The book is intended to be a first step towards an ongoing international focus on potential impact of climate change in the Indian Ocean. Topics are related to current status of operational tropical cyclone forecasting and early warning systems, tropical cyclone genesis, assessment of risk and vulnerability from tropical cyclones and disaster preparedness, management and reduction.
