| Hurricane description | Its winds are at least 119 miles per hour |
| Energy for a tropical storm | comes from warm ocean currents |
| Damage from a storm surge | increased flooding |
| Conditions in the eye of a hurricane | The winds are gentle and there is no rain |
| Average wind speed about 190 to 200 km. | Weather data during a tornado |
| Hurricane models | predict the path of a hurricane |
| Information predicted by hurricane models | a hurricane's strength, direction, & speed |
| vertex | an area where air and liquid spins in a circle |
| storm surge | a rise in sea level caused by a storm's winds |
| tropical depression | storm winds increase and begin to swirl |
| tropical storm | Winds in a tropical depression blow at speeds faster than 62 kph |
| tornado | a funnel cloud that comes down out of a thunderstorm & touches the ground |
| Data scientists use to classify tornados on the Fujita Scale | amount of damage & wind speed |
| Action to take when a tornado warning is given | Immediately take cover in a safe space, such as a basement |
| Ways a tornado & hurricane are similar | They both have dangerous winds |
| Stages of hurricane development | tropical depression, tropical storm, hurricane |
| Stage 1 Tropical depression | low pressure system forms over warm ocean water-thunderstorms form, winds up to 61 km per hour |
| Stage 2 Tropical storm | Thunderstorms move in spiral bands towards an area of low pressure-winds exceed 62 kph |
| Stage 3 Hurricane forms | when the winds exceed 119 km per hour |
| Hurricane damage | Severe flooding, storm surges, & mudslides |
| Tornado damage | Anything in its path can be picked up and thrown |
| Data gathered by scientist | how heat moves, computer models, wind speeds, paths of a hurricane |
