| 1. | The swirls system developed by hko was highly regarded by the experts in the workshop
天文台的小涡旋临近预报系统得到与会专家一致的高度评价。 |
| 2. | It sends out pulses of radio waves and measures the frequency of waves reflected by small eddies in the atmosphere
它发射无线电波脉冲，并量度电波被大气的小涡旋反射后的频率。 |
| 3. | The shift in frequency from transmitted waves gives the velocity of the eddies , which move along with the wind
电波经反射后的频率偏移，可测定小涡旋的移动，亦即是风向和风速。 |
| 4. | The detachment of ring - like vortex from hair - pin vortex induces the breakdown of the head of hair - pin vortex . then the broken small vortex structures move towards the wall
环形涡的形成会引发发卡涡头部的破碎，破碎的小涡结构向壁面运动。 |
| 5. | These small vortices brought significant changes to the headwind locally , as amply demonstrated in the accompanying figure which shows the headwind changes between the weather buoy and the anemometer near the 07l touchdown zone
这些小涡旋令飞机感受的逆风产生显著变化，这点从浮标气象站及07l跑道陆区风速表的逆风变化图可清楚看出来。 |

| 7. | This successive change in wind direction at the buoy , against rather steady winds in the background , suggests the existence of small vortices one by one , over the western part of the airport , and their subsequent movement to the northwest
浮标气象站在背景风稳定的情况下出现以上的风向转变，显示在机场以西有些小涡旋一个接一个移向西北。 |

| 9. | The effects of jet velocity ratio and skew angle were addressed . several co - rotating minute vortexes on the turbulence boundary layer would coalesce together that leaded to a big vortex . the effect of the big vortex was greater than a single minute one
单排多个同向射流与主流作用所产生的独立小涡旋将在流向下游发生合并，形成大涡旋，大涡旋对边界层的作用效果要强于单个独立小涡旋。 |
