Technical Description

The global Extreme Wind Risk Projection products capture projected risk of extreme wind across the globe using simulated future surface wind speed data. These risk maps reflect the future risk from extreme wind in global land regions at decadal time steps for Shared Socioeconomic Pathway SSP5-8.5. These maps use future CMIP6-based projections of wind speed to calculate likely changes to extreme wind conditions into the future. The spatial scale for this dataset is 11 km/pixel and data is available for the years 2030 - 2090 (where windows centered around the year are used to calculate the projected extreme wind conditions). Extreme wind probabilities (between 0-1), expected number of extreme wind days per year (out of 365), and rescaled extreme wind index values (between 0-100) are provided for the combinations of SSP and time horizon.

This dataset contains the following fields:

  • extreme_wind_probability: Probabilities (or alternatively frequencies) of extreme wind occurrence at pixel locations over the future decadal 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. For instance, a 0.5 score for 2050 would indicate that half of the days between 2045 and 2055 were over extreme wind conditions for that location. In other words, there is a 50% probability that the location would be in extreme wind conditions on any given day in that decade.
  • 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 projected extreme wind risk values. This is a value between 0-100.
