What is the most effective tool for predicting tornadoes?
Doppler radar indicates the presence of mesocyclones, or rotating wind fields that are likely to produce tornadoes. When combined with reports of actual tornadoes, Doppler radar provides valuable measurements that meteorologists can use to make their future predictions more accurate.

What data do scientists collect on tornadoes?
Data is collected from a number of sources — radar, observation stations, weather balloons, planes and satellites, and a network of 290,000 volunteer storm spotters — and then fed into vast mathematical simulations that churn out detailed local forecasts of what may happen in a few hours’ time.

Why do tornadoes not hit big cities?
First, since urban areas only cover 3% of America’s land surface, it’s more difficult for a tornado to strike a city because 97% of the nation is not urbanized (which is likely why many people believe cities are protected from twisters).
What should you not do during a tornado?
