Tornado tracks

Posted by Kim Rees on May 26, 2012

John Nelson of IDV Solutions put 56 years worth of tornadoes on a map. John plotted each tornado’s path and used brightness for its F-scale (level of intensity). He also added secondary charts for deaths and injuries and frequency by F-scale.

It makes a gorgeous map. I would love to see the data incorporated into the wind map.

So… practically speaking, if you live in the Midwest or Southern US, you should probably put this on your reading list.

  • Excellent choice with the dark background and lightness by F scale. The blue is gorgeous and the symbolization very effective.
    A few things that would make this even better – use a map projection that does not cause excessive E-W distortion in the northern part of the country. The relative density and intensity of Tornadoes is diminished in the northern section of the country making it extremely difficult to compare to the southern section. The hillshade base is also distracting. Cheers, Karen

  • are tornado tracks really that straight?

  • Are tornado tracks really that long? Are these rather the tracks of the storm systems that spawned the tornadoes?

  • We’ve recently made an interactive version of this map, where you can navigate the geography and time of this data and filter by attributes like severity, magnitude, loss, and cost -if you are so inclined.

Think Like a Statistician – Without the Math

I call myself a statistician, because, well, I’m a statistics graduate student. However, the most important things I’ve learned are less formal, but have proven extremely useful when working/playing with data.

Reviving the Statistical Atlas of the United States with New Data

Due to budget cuts, there is no plan for an updated atlas. So I recreated the original 1870 Atlas using today’s publicly available data.

A Day in the Life of Americans

I wanted to see how daily patterns emerge at the individual level and how a person’s entire day plays out. So I simulated 1,000 of them.
