在每年的春末到秋初这一段时间,无论是大雨倾盆,还是小雨淅淅沥沥,都会伴随着闪电.那么,闪电究竟是怎样产生的呢?下面我们就一起来探讨这个有趣的问题.一、闪电是怎样产生的当冷空气与暖湿空气汇合时,暖空气迅速上升形成云雨.在出现暴风雨时,雨滴与冰晶互相摩擦、碰撞,产生强大的空气流,使云中静电荷增加.云层的顶层带正电,底层带负电,同时底层的负电在地面
In the late spring and early autumn this year, both the heavy rain and the drizzle are accompanied by lightning, so what exactly is lightning? Now let’s explore this interesting issue. First, How Lightning Can Occur When the cool air meets the warm and wet air, the warm air rapidly rises to form cloud rain. In the event of a storm, raindrops and ice crystals rub against each other and collide with each other to create a powerful air flow that increases the electrostatic charge in the cloud. The top is positively charged, the bottom is negatively charged, while the bottom negative is on the ground
