Weather Part 1
| Term | Definition |
|---|---|
| Hurricane | Low pressure tropical storm that starts in the western Atlantic and reaches winds above 74mph |
| Hurricane Statistics | Largest of all storms, approximately 10 per year, nearly 400 deaths per year |
| Saffir-Simpson Scale | System for classifying hurricanes by using wind speed and storm surge |
| Hurricane Dangers | Severe winds from 74-155mph, wind direction is counter clockwise and inwards |
| Storm Surge | A dome of water 40 to 60 miles long that moves onto shore near the land fall point of the hurricane |
| Hurricane Formation 1) | The sun heats up ocean water (especially near the equator) |
| Hurricane Formation 2) | By the end of the summer, ocean temperatures reach into the 80's |
| Hurricane Formation 3) | A thunderstorm moves westward off of Africa and into the Atlantic Ocean |
| Hurricane Formation 4) | When upper wind velocities are low, thunderstorms are given a chance to gain strength |
| Hurricane Formation 5) | The fast rising air (supplied by the warm ocean) allows the thunderstorm to gain strength |
| Hurricane Formation 6) | As it grows, Earth's rotation causes it to spin counterclockwise (Coriolis effect) |
| Hurricane Formation 7) | As they build thunderstorms change to tropical depression, then a tropical storm, and finally a hurricane |
| Tornado | A rotating column of air ranging in width form a few yards to move than a mile and whirling at destructively high winds |
| Tornado Statistics | Most violent storms, approximately 1000 per year |
| Tornado Dangers | Sever winds fro 250 mph and above |
| Tornado Formation 1) | Develop from an intense thunderstorm |
| Tornado Formation 2) | Heating is very intense and warm air rises in strong convection currents |
| Tornado Formation 3) | The rising causes a low pressure center |
| Tornado Formation 4) | As air rushes into the center it starts to spin upward |
