Humans do not cause tornadoes. While climate change may affect tornadoes, it is still uncertain how exactly this will play out.
Ultimately, the two primary causes of tornadoes are convective instability, which leads to thunderstorms, and wind shear, which gives those storms the rotation they need to produce tornadoes.
Tornadoes come in all seasons but are most common in spring and summer.
Humans have no control where and if tornadoes occur.
Tornadoes are natural events caused by the right setup of weather conditions. Human-caused climate change may affect where and when tornadoes are most likely to occur, but tornadoes remain a primarily natural phenomenon.
Tornadoes form in the southern hemisphere for the same reason they form in the northern hemisphere. The mechanics are the same. See the related question for what causes tornadoes
I think it's human nature to be fascinated by them.
No. Humans cannot create tornadoes.
No, not withing human means anyway.
Condensation and wind shear are both needed for tornadoes to form. Tornadoes can form along stationary fronts as well.
The winds in tornadoes are extremely fast. The winds can push against and tear away at objects. Winds in tornadoes often carry flying debris that causes damage on impact.
Damage to property, crops, andresources.
It is during the spring that there are may collisions between warm air and cold air. This causes thunderstorms which in turn can produce tornadoes.
