Building a Global Knowledge Base of Lessons Learned from Good Practices in Multi-Hazard Early Warning Systems -- The Tropical Cyclone Early Warning System of Cuba -- The Bangladesh Cyclone Preparedness Program -- The French Vigilance System -- The Warning Management of the Deutscher Wetterdienst -- Multi-hazard Early Warning System of the United States National Weather Service -- The Shanghai Mult-hazard Early Warning System -- Multi-hazard Early Warning System in Japan -- Synthesis of Seven Good Practices in Mult-hazard Early Warning Systems. This book documents seven examples of Early Warning Systems for hydrometeorological and other hazards that have proven effective in reducing losses due to these hazards. The cases studied encompass a variety of climatic regimes and stages of economic development, raging across the industrialized countries of Germany, France, Japan and the United States, to Bangladesh, the island nation of Cuba and the mega-city of Shanghai. Demonstrated characteristics of these exemplary cases are synthesized into ten guiding principles for successful early warning systems that will, it is hoped, prove useful to countries seeking to develop or strengthen such systems within their own borders.
