Lightning⚡️闪电是怎么形成的

Lightning is electricity and electricity involves tiny particles. Some particles have a positive charge and some have a negative charge. The two opposite charges pull towards each other like the north and south ends of magnets. Usually electric charges are fairly balanced, but the turbulent winds of a storm cause electric charges to separate within the cloud. Lightning starts with negative charges moving from the clouds towards the ground. Scientists call it a stepped leader. Meanwhile an upward leader forms as positive charges move up from the ground, usually from tall objects. when a stepped leader and an upward leader meet, it makes a path for a much larger and brighter electric current to shoot up into the cloud. This is what we see in the sky as lightning. 闪电是电，而电涉及到微粒子。一些粒子含有正电荷，一些含有负电荷。两种相反的电荷会彼此吸引，就像磁铁的南北两极。 通常，电荷是相当均衡的，但是一场暴风雨引起的紊流风会导致云朵内的（正负）电荷分离。闪电的形成以负电荷从云朵移向地面为开始。科学家们称之为梯级先导。 同时，当正电荷从地面，一般会从高物体，向上移动时会形成一个上行先导。当梯级先导和上行先导相遇，会形成一个可供更大和更亮的电流射到云层中的通道。这就是我们在天空中看到的闪电。
