...speeders approach. Then they're captured -- in a flash. A combination cameraradar-computer unit snaps the car's license number and the driver's frequently startled face, as well as the date, time, speed and location. Since May, some 1,200 drivers have been nailed by the high-tech Doppler radar system.The film is developed, the license plate number matched to the car owner, and then the offenders are notified by mail. Only clearly photographed drivers are fined...
...paintings inspired by a Fiat speeding down the Via Veneto, the game gets more complex. Nearly all of this series is assembled at Palazzo Grassi, culminating in Balla's Abstract Speed, 1913, one of the few large futurist paintings that can be called a pictorial masterpiece, a thundering black Doppler-effect image in which the shapes of wheel, mudguard and driver dissolve in and out of the shuttling buildings...
...annual trial by tornado during the next two months, this scenario is likely to be repeated at the National Severe Storms Laboratory in Norman, Okla. The lab operates two new research radars that could be the prototypes for a tornado early-warning system. A sophisticated offspring of the familiar Doppler radar used by police to nab highway speeders, these electronic marvels for the first time are letting scientists peer into the very heart of storm systems in which tornadoes are born. Forecasters figure that should allow them to predict, more than 20 minutes in advance, when and where the terrifying...
That toll could be sharply reduced if enough Doppler weather radar stations are built in the tornado-prone regions. In fact the Norman lab's Doppler, propitiously located in the heart of the tornado belt, has already shown its future value. On April 10 last year, the radar spotted the evolving tornado-producing storm that devastated Wichita Falls, Texas...
Conventional radar stations on which Tornado Alley still depends are capable of picking up certain telltale signs that can presage tornadoes, including so-called hook echoes-reflections from areas of heavy precipitation surrounding a rotating parcel of air. But they cannot detect actual movement within the storm. By contrast, Doppler radar not only measures the direction of air flows, but actually clocks the speeds of raindrops and ice particles as they are whirled about in a brewing tornado...
