Across
- 2. violent downdrafts that are concentrated in local area
- 4. extended period of below-average temperatures caused by a large, high pressure system of continental polar or arctic origin
- 7. type of thunderstorm caused by and advancing cold front
- 9. occurs when an air mass air rises from orographic lifting
- 11. caused by shifts in global wind patterns, allowing high-pressure systems to remain for weeks or months over continental areas
- 13. extended period of above-average temperatures caused by large, high-pressure systems that warm by compression and block cooler air masses
- 15. extremely powerful, self-sustaining thunderstorm characterized by intense, rotating updrafts
Down
- 1. channel of partially charges air; the breakdown in charges in between positive and negative regions
- 3. occurs when powerful, hurricane-force winds drive a mound of ocean water toward shore, where it washes over the land, often causing enormous damage
- 5. air rises because of unequal heating of Earth's surface within a single air mass
- 6. a branch channel of positively charged ions that rushes upward from the ground to meet the stepped leader
- 8. violent, whirling column if air in contract with the ground
- 10. band where the strongest winds in a hurricane are usually concentrated, surrounding the eye
- 12. large,low-pressure, rotating tropical storm that get its energy from the evaporation of warm ocean water and release heat
- 14. calm center of a tropical cyclone that develops when the winds around it center reach
