How the Totable Tornado Observatory Worked
Totable Tornado Observatory: Cheat Sheet
Stuff You Need to Know
- Because of an unusual phenomenon known as dryline, the United States is nearly the exclusive setting for tornado activity in the world.
- In 1979, two NOAA scientists stuffed a 55-gallon (208-liter) steel drum with thermometers, pressure gauges, an anemometer and a dew point sensor. This was the first TOTO.
- TOTO weighed 400 pounds (181 kilograms) but could be deployed in 30 seconds.
- After six years of near-misses and one bull's eye, TOTO was retired from service and sits in the lobby of the National Weather Service building in Norman, Okla.
