Cumulonimbus. big billowing clouds that look like mushrooms.
cirrus clouds
I'm pretty sure that's the only kind of lightning.
Cumulonimbus clouds form lightning
Cumulonimbus clouds are clouds that produce lightning.
Clouds that produce lightning have electrical energy. This energy is generated by the separation of positive and negative charges within a cloud, which results in the discharge of lightning as a way to balance these charges.
One kind of lightning is a connection between two charged clouds. But you asked where it "lands", so you must be thinking about the other kind. Lightning is a connection between a charged cloud and the Earth. If there are objects around that can provide an easy path to the Earth, like trees, houses, skyscraper buildings, or steel radio towers, then lightning will take advantage of them and use them for part of its path. But even if there's nothing around that's any higher than the ground, and the lightning is forced to make the entire trip through air, it'll do that, and eventually connect the charged cloud to the Earth. I've written this carefully, to avoid any reference to one direction or the other, because lightning can travel up, from the ground to the cloud, just as easily as it can travel down, from the cloud to the ground.
That's how you spell it. The kind in the sky during a storm...
Lightning is a common noun.
cumulonimbus
Lightning is a form of electrical energy caused by the build-up and discharge of electricity in the atmosphere during thunderstorms.
No type of cloud is associated with tusnamis, as a tsunami is not a weather-related phenonomenon. A tsunami can occur during absolutely any type of weather.
the charge of a lightning is positive and negative. The positive is on the top of a lightning cloud and the negative is surrounded on the bottom. As it flashes down it is a negative. However, the ground is a positive charge so as it reaches down, it turns into a positive charge. I hope this will answer you question
