A tornado is a microscale weather pattern, meaning that in weather terms its is very small and fairly short lived, and so it can be influenced by small-scale and short lived factors. These factors interact in complex ways. What causes a tornado or its parent thunderstorm to go through one place and not another is influenced by differences in temperature, humidity and wind too subtle to even detect on the long term, especially considering that we cannot take measurements at every single location. It is only when the direct precursors to the tornado, which typically gather together in a matter of minutes, can we say that a specific location is at risk.

That said, a less definite sort of prediction can be made on more long term. Many tornadoes, especially the strong ones, tend to occur in outbreaks. In these circumstances large-scale weather patterns have to have a favorable setup for tornadoes across a region. Such large scale patterns are easier to work with. With this we can often tell that a tornado outbreak is likely across a region three days in advance, sometimes more. However, such forecasts cover broad areas such as a state or two and cannot predict if any specific location will be hit, or exactly how strong the tornadoes will be.

When will be the next quiet tornado?

First of all, tornadoes are not quiet. It may be quiet before a tornado hits, but not in the tornado itself. Second, it is impossible to predict when or where the next tornado will hit.

How do earthquakes work?

It is not possible to predict an earthquake yet. But many scientists believe animals can predict earthquakes. Before the 2004 earthquake (that trigged the massive tsunamis) reports of elephants becoming restless and running to high ground came about, and pets refusing to go outside, etc. If a major earthquake happens, aftershocks can occur for months, but still scientists cannot predict when or how strong or even where the exact location of the aftershock will be.

What can scientist do to understand the mechanisms of how a tornado froms?

Scientists study tornadoes by scanning them with Doppler radar, measuring conditions near and before a tornado with instruments, and deploying probes inside a tornado. The last approach has met with little success.


What means predicting?

The verb predict means: to tell that something will or won't happen in the future.To 'predict' is to foretell - to say that something WILL happen before it happens.


What happens before a tornado strikes?

It varies but most often it stops raining a few minutes beforehand. A break in the clouds may be seen, a sign of a downdraft that helps the tornado form. A number of tornado survivors recall it being unusually quite just before the tornado hits.


Can scientists predict volcanic eruptions?

Yes, scientists can predict volcanic eruptions, but only to a certain extent of accuracy. One method is to use earthquakes. Earthquakes usually increase and become more violent before a volcanic eruption
