Formation and anatomy of a severe, tornado-producing thunderstorm.

I think you all know what it is. So how does it work? What happens is that the sun begins to warm the ground at morning. By late morning the sun has heated the earth and air enough to evaporate the water out of them. As the moisture starts to rise up it starts to condense into a thick fog once it gets up into the sky. That fog is the cloud. As the sun starts to warm the cloud which by now is a cumulus cloud, the cloud grows even bigger cloud, the type called culomonimbus. This is the thunderstorm cloud. As the heat inside the cloud builds up, it causes the cloud to expand upward. If it extends upward enough you can see its tip being blown to the side by high altitude winds, making it look like an anvil. And inside the cloud there is huge friction created between the water droplets and ice particles at top of cloud. This friction inside the cloud causes static electricity. This electricity is then discharged to the ground in the form of lightning.


Now if the storm gets very severe, the energy within it will cause some of its bottom to rotate. This causes the air under the funnel to rotate a well, causind a tornado. A tornado picks up things because of the vacuum within the tornado. This suction is caused because of the rotating funnel. As air spins around it expands outward. This means there is little air inside the tornado, causing the tornado to suck objects up. Now there is more to this type of storm than just a tornado. You will also notice ice pellets falling from the sky. These ice pellets are called hail. These are formed because of when raindrops inside the cloud get pulled up to the top of the cloud they freeze up. Than they go back to the bottom of the cloud again where they will stick to more raindrops. And then they will go to the cloud top again where they will freze again. So the hail pellets start out as raindrops pulled to the cloud top where they freeze, then fall to the bottom of the cloud sticking to more raindrops, forming a bigger pellet, then up and down again. So they rotate up and down within the cloud getting bigger. Then once the pellet of hail attracts enough rain drops to it, it becomes too heavy to stay floating inside the cloud and gets pulled down and falls to the ground as hail pellets. Well I think that's all there is to know about severe thunderstorms. If I come up with more I will post it here. If you need more help understanding this, ask me.
