Technical Description

The Climate Engine Historical Tornado Risk dataset is a raster dataset that captures the near-historical risk from tornadoes across the US and Canada, based on observed/confirmed records of tornadoes. This dataset is based on measuring the frequency of 'tornado days per year' at locations across the US and Canada, using a harmonized record of tornado observations from both the NOAA Storm Prediction Center and the Canadian National Tornado Database from Environment and Climate Change Canada. This dataset's extents are limited to areas in which there was at least a single tornado observed over the course of the analysis period (1980-2010). Tornadoes were not observed at high latitudes (above ~61 degrees North).

This dataset contains the following fields:

  • tornado_days_per_yr_25_mi: the number of days per year that at least one tornado was observed within a 25 mile radius of a given location over the course of the analysis period.
