Global Cyclone Mortality Risks and Distribution

The Global Cyclone Mortality Risks and Distribution is a 2.5 minute grid of global cyclone mortality risks. Gridded Population of the World, Version 3 (GPWv3) data provide a baseline estimation of population per grid cell from which to estimate potential mortality loss. Mortality loss estimates per hazard event are calculated using regional, hazard-specific mortality records of the Emergency Events Database (EM-DAT) that span the 20 years between 1981 and 2000. Data regarding the frequency and distribution of cyclone hazard are obtained from the Global Cyclone Hazard Frequency and Distribution data set. In order to more accurately reflect the confidence associated with the data and procedures, the potential mortality estimate range is classified into deciles, 10 classes of an approximately equal number of grid cells, providing a relative estimate of cyclone-based mortality risks. This data set is the result of collaboration among the Columbia University Center for Hazards and Risk Research (CHRR), International Bank for Reconstruction and Development/The World Bank, and Columbia University Center for International Earth Science Information Network (CIESIN).

《全球台风死亡率风险及其分布》是一项基于2.5分钟网格的全球台风死亡率风险数据集。世界人口网格化数据集，第三版（GPWv3）提供了每个网格单元人口基线的估计值，据此估算潜在的死亡率损失。针对每个灾害事件的死亡率损失估算，采用1981年至2000年间的区域特定于灾害的死亡率记录，这些记录来源于紧急事件数据库（EM-DAT）。关于台风灾害的频率和分布的数据，来源于全球台风灾害频率和分布数据集。为了更精确地反映数据和方法相关的置信度，潜在的死亡率估算范围被划分为十等分，即约等数量的网格单元的10个类别，从而提供基于台风的死亡率风险的相对估算。该数据集是哥伦比亚大学灾害与风险研究中心（CHRR）、国际重建与发展银行/世界银行以及哥伦比亚大学国际地球科学信息网络中心（CIESIN）之间合作的成果。
