問題詳情

＜B＞ In the Hollywood film Twister (1996), a group of scientists chased tornados close enough to drop a“Dorothy” device, which scattered sensors into the heart of twisters to measure their power. The film was looselybased on a real, far less successful, science project.But next month the biggest tornado-chasing project in history will go much farther than Twister. Dozens ofscientists will be armed with an array of instruments – radar mounted on trucks, lasers, unmanned flying drones,mobile weather stations, weather balloons and much else. They will venture out across a broad swath of TornadoAlley, the heart of the US where powerful tornados most often strike, and surround thunderstorms with theirinstruments to find out how tornados form.The basics are known. A clash of warm, humid air and cool air erupts into violent thunderstorms. If thewinds high up in the storm blow at different speeds or from different directions, they can send the storm spinninglike a whirling top, and a funnel of spinning air drops to the ground as a tornado.The most powerful tornados come from thunderstorms called supercells, which also have the power tounleash torrents of rain, huge hailstones and violent gusts of wind. But crucial questions remain – why do so few6supercells spawn tornados? And why do apparently similar storms produce weak or strong tornados? Theanswers will help to improve tornado warnings and save lives.
