Wizard of Oz

Dorothy’s tame tornado quickly got wicked

When Dorothy gets whisked away in “The Wizard of Oz,” the focus is on the magical world she lands in. But what about her transportation?

Even the Scarecrow’s brains could tell you there was a tornado — a strong one.

Using the Enhanced Fujita Scale and a bit of Kansas intuition, David Rahn, an atmospheric science professor at the University of Kansas, helped determine just how powerful it was.

A twister’s rating ranges from EF0 (light damage) to EF5 (incredible damage or total destruction). Dorothy’s farm provides some key clues to what movie-makers had in mind.

As everyone scrambles for shelter, a tree snaps and blows away. And even though Dorothy appears planted firmly on the ground, the scene indicates winds of about 100 mph, or an EF1, Rahn said.

Dorothy runs inside as a screen door flies off its hinges, searching for Auntie Em to no avail. A window blows out, shattering as it hits her. She’s conked out, thus beginning her fantastical trip to Oz. Still, Rahn insists, this damage still only corresponds to an EF1.

An EF1? This storm took Dorothy all the way to Oz at an EF1?

Not quite. As her head spins, so does the twister. When Dorothy begins to dream, the house is lifted off its foundation.

“I think it is pretty safe to bump up the tornado rating to an EF5,” Rahn said. “And commend whoever built the house, since it’d get ripped apart.”

CYCLONE VS. TORNADO: THE TWISTS OF A LABEL

There’s nary a mention of a tornado in the 1939 movie “The Wizard of Oz.” Twister, yes. Cyclone, yes.

And in L. Frank Baum’s book “The Wonderful Wizard of Oz,” published in 1900, Chapter 1 is titled “The Cyclone”:

Suddenly Uncle Henry stood up.

“There’s a cyclone coming, Em,” he called to his wife. “I’ll go look after the stock.” …

The north and south winds met where the house stood, and made it the exact center of the cyclone. In the middle of a cyclone the air is generally still, but the great pressure of the wind on every side of the house raised it up higher and higher, until it was at the very top of the cyclone; and there it remained and was carried miles and miles away as easily as you could carry a feather.

“Cyclone” is an old-fashioned word for tornado. Before 1950 or so, “tornado” was considered a term that could cause public panic, says Jim Keeney, severe weather program manager for the National Weather Service in Kansas City.

Meteorologically, a cyclone “encompasses all cyclonically rotating — counterclockwise in the Northern Hemisphere — storms, which includes most tornadoes,” Keeney says.

According to the true definition, cyclones are much larger. Tornadoes are smaller, localized events.

The government first issued a tornado warning in 1948.
