| 5. | Occasionally , a microwave pulse reflected from a distant rain area may arrive at the radar after the radar has emitted the next pulse of microwave 有些时候,当从遥远的雨区反射回来的微波到达雷达时,雷达已经再次发出脉冲。 |

| 7. | However , as the plane approached the intense rain area , winds abruptly backed to northerlies coupled with a rapid increase in downdraught to over 30 knots 但是当航机接近大雨区时,风向突然转为北风,并出现急剧加速的下沉气流,时速超过30海里。 |
