| 1. | Impact of windshear on ascending or descending air crafts
风切变对升降中航机造成的影响 |
| 2. | The descending air is cool and dense , and spreads out on hitting the ground
下沉的空气较冷和密度高，在接触到地面时会向外扩散。 |

下沉的空气较冷和密度高，在接触到地面时会向外扩散。 |
| 4. | The " eye " is typically of the order of tens of kilometres in diameter . it is essentially a core of descending air where clouds are relatively broken and winds are relatively calm
典型的风眼直径大约有数十公里，实质上是下降气流构成的核心，该区云层稀薄，风力微弱。 |

| 7. | Due to the sun radiation , the heated and expanded surface air ascends and meets the cold descending air , this air convection causes the turbulence which is obvious at noon
这是因为太阳光的照射，使地面的空气受膨胀上升，冷空气下降补充，形成空气对流而引起的颠簸，中午飞行尤为明显。 |
