Because its always changing and there are too many possible factors to make an accurate prediction.
We can, to a limited degree. Tornadoes develop rapidly from relatively small-scale weather systems and are sensitive to small changes in the atmosphere that are difficult to detect. This makes them hard to predict.
Pretty much yes it is difficult because it is impossible to predict weather because we don't know what will happen next because we don't know the future.
Overall it is extremely difficult to predict tornadoes. By weather standards tornadoes are small and form quickly, usually occurring on a time scale of minutes or seconds. Additionally, how a tornado works is still largely unknown.
Doppler radar is used to predict tornadoes when they're already occurring.But aside from that tornado predictions are very uncertain and difficult to make. The durations of tornado warnings are counted in minutes and even then there are many false alarms.
They send space people go into space and predict.
difficult
The future is difficult to predict accurately (but very easy to predict inaccurately) so allow me to predict that Africa is facing a difficult future.
it is so difficult to predict becuz sometimes the storm may be gone, weaken, or strengthen.
No, it is not
No Aristotle did not predict the end of the world.
Cobalt is difficult to predict the most probable ionic charge due to the fact that it has various oxidation states.
No, Pope Leo X did not predict the end of the world for 2014. There are no recorded predictions made by Pope Leo X regarding the end of the world.
The more difficult it is to identify and predict
a hail storm or tornado.
It can be difficult to predict what the stock market will do in the future.
According to the Mayan calendar, it is thought to end at the year 2012. -As we are now in January of 2013, it proves that the future is difficult to predict, at best.
Tsunamis are difficult to predict because the earthquakes that cause them are difficult to predict. It takes a massively powerful earthquake to displace the amount of water needed to cause a tsunami.
