Global Cyclone Hazard Frequency and Distribution

The Global Cyclone Hazard Frequency and Distribution is a 2.5 minute grid based on more than 1,600 storm tracks for the period 1 January 1980 through 31 December 2000 for the Atlantic, Pacific, and Indian Oceans that were assembled and modeled at UNEP/GRID-Geneva PreView. Windspeeds around storm tracks were modeled using Holland's model (1997) to assess the grid cells likely to have been exposed to high wind levels. Post-modeling, the cells were divided into deciles, 10 classes consisting of approximately equal number of grid cells. The higher the value of the grid cell, the higher the decile ranking and the greater the frequency of the hazard relative to other cells. 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, United Nations Environment Programme Global Resource Information Database Geneva (UNEP/GRID-Geneva), and Columbia University Center for International Earth Science Information Network (CIESIN).

《全球气旋灾害频次与分布》数据集，基于超过1600条风暴路径，以2.5分钟网格为单位，对1980年1月1日至2000年12月31日期间大西洋、太平洋和印度洋的气旋灾害进行了汇编和建模，该工作由联合国环境规划署/日内瓦网格预览中心（UNEP/GRID-Geneva PreView）完成。利用Holland模型（1997年）对风暴路径周围的风速进行了模拟，以评估可能遭受高风速的网格单元。建模完成后，网格单元被划分为十等分，即包含约等数量网格单元的10个类别。网格单元的数值越高，其十等分排名越高，相对于其他单元而言，灾害发生的频次也越大。本数据集是哥伦比亚大学灾害与风险研究中心（CHRR）、国际复兴开发银行/世界银行、联合国环境规划署全球资源信息数据库日内瓦（UNEP/GRID-Geneva）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。
