It was a really stormy night last night. The lighning went on all night till the morning. It was like back home. The aftermath in the morning was quite disastrous. By 7 am, two main motorways leading to Amsterdam and The Hague were jam locked a distance of 30 km. Broken trees and branches were everywhere on the road.On the subject, I learnt something new from Zimah. She said lightning comes from the ground. I was 100% sure that lightning comes from the cloud until I saw this answer
Does lightning travel from the ground up or from the cloud down?
A: The short answer is from the ground to the cloud, but it's a complicated process. When too much negative charge builds up in a cloud, a bundle of charge moves from the cloud toward the ground in the form of a "stepped leader." As a stepped leader nears the ground, it attracts a surge of positive charge that streams skyward from the tallest nearby objects. The stepped leader and "streamers" typically meet around 100 to 300 feet above the Earth, forming a path for the lightning stroke. As electrons race from cloud to ground, a return stroke of current shoots up from the ground. It is this surge of current that we see as lightning.
