A few years ago, Cornman found a way around the problem. In the U.S., commercial flights served by air-traffic control—some twenty-seven thousand a day—are required to transmit their position, altitude, and velocity. By tracking those transmissions and the planes’ motions over time, a new program that Cornman developed at NCAR can create a moment-by-moment snapshot of turbulence as it’s happening. The F.A.A. is planning to test the program this year. Together with NCAR’s earlier software, Sharman’s forecasting models, and data from radar arrays on the ground, this system could start to give pilots the advance warning they need. “That is the future for me,” Cornman said. “All these operations get integrated in a seamless network. The pilots don’t have to talk to air-traffic control and say, ‘Should I go up or down?’ They just get a display with a color-coded flight track on it. And they see that it looks better a few thousand feet up.”
当然，不用说，我中华也艰难，也受尽磨砺，甚至于稼轩的大宋也有悲催与深憾，有懦弱与腐败，等等。“靖康耻，犹未雪。臣子恨，何时灭”（岳飞词），辛稼轩自己更多写下的是“醉里挑灯看剑”“可怜白发生”“西北望长安，可怜无数山”。，推荐阅读体育直播获取更多信息
