| 1. | However , in this case , it was a little unusual that lenticular clouds were observed on a summer day
在清凉季节，空气比较稳定，荚状云较为常见，在夏天出现的机会不大。 |
| 2. | Lenticular clouds are evident of wave motions in the airflow over and to the lee of mountains , where moisture in the air condenses into water droplets as a result of the upward motions
当气流攀山时，空气内的水分会凝结成云。荚状云是印证气流在经过山时或在山背地方出现波浪似的运动。 |

| 4. | Since lenticular clouds look like one or more convex lens , they could sometimes be misinterpreted as flying saucers or unidentified flying objects , and so they are commonly known as " flying saucer clouds "
由于这类荚状云形状像一块或多块凸透镜，有时候被误会为飞碟或不明飞行物体，所以亦俗称飞碟云。 |
| 5. | I took the first photograph below at 10 a . m . , 8 february 2006 near the observatory s headquarters in tsim sha tsui , showing clouds over kowloon which resemble a pair of flying saucers . these clouds are called " lenticular clouds "
以下第一张相片是我在2006年2月8日早上10时在尖沙嘴天文台总部附近拍摄，可见九上空出现两团类似飞碟的云，我们称这种云为荚状云。 |
| 6. | However , in this case , it was a little unusual that lenticular clouds were observed on a summer day . it is believed that a weak stable layer ( an inversion in weathermen s terminology ) at around the hilltop level might have contributed to the cloud formation
如果我们将图中ab线作一垂直切面，便可清楚见到风力随高度的转变(图20 ) ，即较强烈但浅薄的偏西气流集中在地面附近，而在上空的风则较弱。 |
