| Abstract | Global Cyclone Hazard Frequency and Distribution is a 2.5 by 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. The dataset is the result of collaboration among the 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 the Columbia University Center for International Earth Science Information Network (CIESIN). The source of the data is Center for Hazards and Risk Research (CHRR) at Columbia University, (http://www.ldeo.columbia.edu/chrr/research/hotspots/) and Center for International Earth Sciences Information Network (CIESIN) at Columbia University (http://www.ciesin.columbia.edu). |
