| 2. | The explosive expansion of the surrounding air produces the rolling sound of thunder . as a rule of thumb , if the sound of thunder reaches an observer three seconds after a lightning flash , the thunderstorm is about one kilometre away from the observer 简单来说,在看见闪电后三秒才听到雷声,表示雷暴距离观察者约一公里,真正的距离依时间长短按比例计算。 |

| 4. | When the electric field arising from the piling up of charges reaches a certain breakdown value , lightning discharges take place between clouds or between cloud and the earths surface . the explosive expansion of the surrounding air produces the rolling sound of thunder 当电荷累积而形成的电压过大时,云与云之间或云与地之间就会出现闪电放电现象,放电通道周围的空气会急剧膨胀而产生隆隆雷声。 |
