How Do the Deadliest Storms in the World Form?

Hurricanes are similar to tornadoes, but they form over water. While the official name for these types of storms is tropical cyclones, they are also called typhoons or cyclones, depending on where they occur. They cause damage to coastal cities and can kill thousands of people, and leave thousands of others homeless.

Hurricanes usually form in a tropical place when the sun heats the water, which then evaporates and cools into clouds. As the hot air rises, cold air rushes in to fill the space. Next, the clouds and warm air begin to spin and grow from the ocean's heat and surface water evaporation. The middle of the storm is called the eye.

These storms mostly hit Texas and the southeast coast of the United States and weaken after hitting land. In 2010, a Category 3 Hurricane hit Ireland and the United Kingdom. The hurricane first hit the United Kingdom with 100 mile-per-hour winds. Then, when it hit Ireland, the hurricane underwent a transition that slowed the winds down to 80 miles per hour.

While Wisconsin doesn’t get hit by hurricanes, the effects of the strong hurricanes can still be felt here. When hurricanes hit land, it can turn into a thunderstorm, cause strong floods, and spawn tornadoes.
