<human>:  Can you explain the differences between a hurricane and a tornado?
<bot>: A hurricane is a large, rotating storm system that typically forms over oceans in the tropical regions and moves toward land. Hurricanes usually have sustained wind speeds of 74 mph or higher and intense rainfall. Tornadoes, on the other hand, are small, intense rotating columns of air that form when large thunderstorms develop in the middle latitudes and move towards land. They usually have peak wind speeds of around 110 mph, and often don’t bring much in the way of rain.
