Global Cyclone Hazard Frequency and DistributionEntry ID: CIESIN_CHRR_NDH_CYCLONE_HFD
Abstract: 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 dataset 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).
The data in American Standard Code for Information Interchange (ASCII) format and a map in Portable Document Format (PDF) and Portable Network Graphics (PNG) formats are available from the NASA Socioeconomic Data and Applications Center (SEDAC).
Purpose: To provide a means of assessing the relative distribution and frequency of global cyclone hazard.

Quality Various sources of tropical storms were organized into GIS coverages by Pascal Peduzzi and Christian Herold of UNEP/GRID-Geneva. Each storm track was buffered using Holland's asymmetrical wind speed profile model. These buffered areas represent the areas exposed to cyclones.
The different wind speed buffers were translated into six categories using the Saffir-Simpson Hurricane scale. Overlaying a 1 km resolution grid produced a surface representing how often a grid cell is hit by a hurricane and the associated wind speed, a measure of severity.
The final surface classified the range of frequency into deciles, 10 classes of approximately an equal number of grid cells. Ten represents cells that are the most hazardous, while 1 denotes the least hazardous. Note that areas of no data are not necessarily areas without hazard, but rather that a mask was used to exclude from analysis those areas that had a population density less than 5 persons per square kilometer and without significant agriculture.
