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.”

随着霍尔木兹海峡的航运明显受阻，全球航运业已遭受明显冲击。有航运业分析人士将现在霍尔木兹海峡附近的情况，形容是：规模巨大的海上交通拥堵。国际石油经纪公司Oil Brokerage表示，根据他们的最新统计，目前至少有100艘油轮被困在霍尔木兹海峡内侧，无法驶出。同时，还有100多艘船只能在海峡外等待进入。此外，目前还很难准确评估从海湾地区运输石油的真实成本。相关油轮运费出现飙升。DBRS晨星还预计，今年大型航运企业的盈利将出现下滑。在当前冲突中，专注于原油运输的油轮公司受到的波动影响最大；相比之下，业务更加多元化的企业，例如拥有位于受影响地区以外收入来源的公司，在应对冲击方面更具韧性。（央视财经）
