What’s in a name of a hurricane?

A few months ago, a study came out in PNAS that sparked a lot of media interest: Female hurricanes are deadlier than male hurricanes. The idea is not that the most severe hurricanes happen to have female names, but instead that more people die in hurricanes that have female names than in those with male names.

For hurricanes that had greater damage, however, the number of fatalities was substantially higher for female-named storms than for male-named ones. Further, they classified names for how masculine or feminine they are (referred to as the Masculinity-Femininity Index, or MFI). For example, a highly feminine name would be “Eloise,” (with a score of 8.944) while the female name “Charley” was rated as much less feminine (MFI = 2.889). The researchers found that even within feminine-named hurricanes, the more feminine a name was (the greater the MFI score), the higher the number of fatalities. Specifically, their data suggest that if a severe hurricane’s name is Eloise, it will kill 3 times as many people as if it’s named Charley. The explanation for the correlation between might seem intuitive and surprising at the same time: we have gender-based expectations that females are less aggressive. This unconscious bias seems to invoke a lower perceived risk for female hurricanes, so people take fewer precautions like evacuating. In light of these findings, The World Meteorological Organization (WMO), the group who names the storms, might want to reevaluate its naming practices to avoid names that might encourage dismissal of a hurricane’s danger. In case they’re looking for inspiration, I have a few suggestions. What NOT to name a female hurricane:

  • Any flower name: this includes Daisy, Petunia, Lilly, and sadly, Rose
  • Pooh Bear (imagine the reactions if meteorologists announced that Hurricane Pooh Bear was headed for the coast)
  • Any name that has repeated syllables: can we expect people to take Coco or Fifi seriously?
  • Any name that’s shared with a Barbie doll, like Skipper, Stacie, and certainly Barbie
"Hurricane Barbie is on her way!"

Hurricane Barbie is on her way!

And some names that people might take more seriously:

  • Names that invoke big, tough women you wouldn’t want to mess with: Bertha, Agnes, or Madea
  • Gender-neutral names, like Alex, Casey, or Jamie
  • Non-human names: names like PX-750 or The Hulk might do the job
If you heard "Hurricane Madea is heading for the coast," what would you do?

Don’t mess with Hurricane Madea.
