Since tornadoes are a form of weather, they would be predicted by a meteorologist.
Droughts can be predicted up to a point. Meteorologists can use current and past weather patterns and climate trends to determine whether or not these meteorological influences will result in reduced rain in a particular region. The El Nino weather pattern, for example, brings dry conditions to Australia which invariably result in drought in many areas of the country. El Nino is known to occur on average every 2-7 years, and oceanographers and meteorologists watching the Southern Oscillation Index (SOI) can determine whether the region is entering an El Nino phase.
The Eyjafjallajokull volcano was predicted because the only way was to see if there were any earthquakes or tremors or magma.
Not very. I was once a professional Vietnamese weather forecasting team's lead meteorologist, when, I spotted a pretty particular set of clouds descending towards a local canyon. I predicted that the shower would not only produce rain of "Cat's and Dog's" but horses as well. Much to my surprise, there were no horses, because, as we all know, horses don't swim.
Weather is predicted at the scene of were it happens, or at a weather station.
Can't prevent them but they are predicted by weather observations. This is called meteorology. Tornados can be predicted but what can't be predicted is how they move or where they will go next.
