摘要
冬季辐射雾是成都双流机场影响航行的严重问题。1985—1987年冬季在机场进行了辐射雾的宏微观探测,将取得的资料进行了分析,井选用热力动力方法进行消雾试验。试验结果表明:喷气发动机开始工作2分钟后,在影响区内雾滴蒸发了,消雾面积为6000m^2,能见度由试验前30m改善到260m。 1.雾的气侯特征 雾的观测场地距成都市约15km,北面有九顶山,西面有邛崃山,东面有龙泉山,南面有牧马岴,并处于盆地中心位置。这个地区终年日照少,阴天日多,雨量充沛,湿度较大。每年雾日出现机率最多集中在11月至次年2月。
The radiation fog is a serious problem to aviation at Shuangliu airport in Chengdu in winter time. A project of field observation on the micro-physics of fog were carried out at this airport during the winters of 1985-1987. After the analyses of field observation data a set of fog dissipation experiments was performed using a thermo-dynamic method. The results show that all the fog droplets are evaporated in the target area only two minutes after the jet engine working. The cleanout area is about 6000m2 and the visibility is improved from 30m before the experiment to 260m.
