Mobile scientific laboratory
Doppler on Wheels is an advanced mobile scientific laboratory. Along with hundreds of twisters, it has also chased several hurricanes, expanding what we know about those storms.
Positioned on the Louisiana coast for Hurricane Gustav in 2008, the fleet captured high resolution measurements as the hurricane came ashore. The images show winds in surprising corkscrew rolls.
“And that corkscrewing motion does two things," Wurman said. "One, it brings strong winds down to the surface and those stronger winds have a much greater potential to cause damage. But in addition, on the way back up, those winds are carrying heat and moisture from the ocean, which is basically the food, the fuel for a hurricane.”
For tornados, the false alarm forecast rate has hovered around 75 percent for decades. Looking at those winds could give forecasters a better idea of the intensity of the storm, which could translate into more accurate forecasts. And that, Wurman says, can save lives.
