Technical Description

The Extreme Wind Historical Risk product captures the recent near-historical risk of extreme wind events across the globe using historical wind speed reanalysis data. This extreme wind product seeks to identify areas across the globe where historically observed extreme wind events have posed risks to the built environment and human life. This product can be used to assess the frequency of extreme wind at different locations, or to identify relative risk across different regions at a single time horizon.

This dataset contains the following fields:

  • extreme_wind_probability: Probabilities (or alternatively frequencies) of extreme wind occurrence at pixel locations over the historical period of record used for calculation. Technically unitless but represents counts of extreme wind occurrences divided by the total number of data points. This is a value between 0-1.
  • avg_extreme_wind_days_per_year: The average number of days per year over the historical period of record used for calculation that are classified as extreme wind days. This is a value between 0-365.
  • extreme_wind_index: The extreme wind probabilities but rescaled to between 0 and 100 based on the minimum and maximum values in the map. This allows for a simple relative scoring between pixel locations based on their historical extreme wind risk values.
