1.A tornado (龙卷风) is a violently turning column of air that is in contact with both the surface of the earth and a cumulonimbus cloud (积雨云).Tornadoes come in many shapes and sizes,but they are typically in the form of a visible condensation funnel (漏斗).Most tornadoes have wind ...
A fire tornado in California was likely formed by miles-high heat plumes that crashed into the higher atmosphere. True fire-caused tornadoes are very rare, with just a few documented instances before this year. Compounding climate-change factors have likely increased the number of fire tor...
Tornadoes are extremely devastating, as they can cause serious damage to homes, structures, and the environment. How Tornadoes are Formed Tornadoes are formed when warm air collides with the cold and dry air. The temperature difference creates atmospheric instability, which leads to the formation of...
3.Whirling dust debris above the ground (similar to a ‘dust devil’ but bigger).If you notice this beneath a large storm cloud base, it may be a tornado sign that one may have already formed but is still up in the cloud. It’s strong updraft is pulling air up into it which is r...

Learn about how tornadoes are formed with this simple tornado in a bottle activity. My son enjoys checking the weather and temperature every day! We recently checked out the book Otis And The Tornado from the library, and he inquired about a homemade tornado bottle we had previously made. He...
How a tornado is formed: A tornado is a violently rotating column of air extending from a thunderstorm to the Earth's surface. Scientists have yet to fully resolve the mystery of how a tornado is formed, but usually, it generates from thunderstorms. The most violent tornadoes come from super...
You can learn more about tornadoes and how they're rated in How Tornadoes Work. So if a tornado can fling a car and turn a house into toothpicks, how in the world can anyone survive standing in the eye of the beast and what's it like in there? We'll get two firsthand accounts ...
Tornado - read about tornadoes, how they form, preparing for a tornado, surviving one, and the end of the storm.
How tornadoes form Tornadoes are formed from large thunderstorms called supercells or rotating thunderstorms. A supercell contains a rotating updraft called a mesocycle. The mesocycle draws in warm air from the thunderstorm, causing it to build speed. When the warm air mixes with cool air, the ...
