...closer to 2000, the stock-taking increases. As mille.org, a millennial watch Web site, points out: "Millennialism operates...like a Doppler effect: at the approach of a given date or time: it crescendos with accelerating intensity, and, the moment passed, fades rapidly...

...hours, a legion of twisters--more than 40, coming so fast that the exact count is uncertain--scourged the region. One, a behemoth originating near Chickasha, may be historic. Not for the width of its funnel--although at nearly a mile across, that was extraordinary--but a mobile Doppler radar from the University of Oklahoma clocked its peak wind speed at 318 m.p.h., which would make it the strongest wind recorded on Earth...

...never indifferent to a passing fire truck. My head would follow the Doppler effect, twisting around to see the pulsating lights disappear off to perform acrobatic feats of heroism about which I could only imagine...

...these high-tech times, ranchers had used cell phones to call in warnings to their families as others watched Doppler Radar reports on Austin and Waco television stations. Al Clawson, the owner of a small recycling plant, was at home when the tornado siren went off. "I seen the tornado on TV, and I called my wife and daughters at the plant and told them to get in their cars and run," he says. And run they did. The twister was a malignantly playful one, first appearing as a single funnel, drawing back and then suddenly combining at least three...

...provide what radar meteorologists refer to as "ground truth." At the time, the NSSL was developing a radar capable of detecting areas of strong rotation inside big tornado-producing storms. The chasers provided visual proof that particular radar signatures did indeed precede the formation of tornadoes. The new radar, Doppler radar, made use of the fact that radio waves shift frequency depending on whether the objects they bounce off are advancing or receding. In this case, the objects that create the Doppler shift are water droplets inside storm clouds. As the winds inside these clouds begin to spin, the droplets...
