Hurricanes are Earth's strongest tropical cyclones.
A distinctive feature seen on many hurricanes and are unique to them is the dark spot found in the middle of the hurricane. This is called the eye . Surrounding the eye is the region of most intense winds and rainfall called the eye wall . Large bands of clouds and precipitation spiral from the eye wall and are thusly called spiral rain bands . Hurricanes are easily spotted from the previous features as well as a pronounced rotation around the eye in satellite or radar animations.
