5. streamer = currents of positive charge moving upwards from the ground, up elevated objects like trees
8. a localized and violently destructive windstorm occurring over land characterized by a funnel-shaped cloud extending toward the ground
10. a long period without rain
11. violent downdrafts that are concentrated in a local area
12. band where the strongest winds in a hurricane are usually concentrated, surrounding the eye
13. Measures the windchill factor, by estimating the heat loss from human skin caused by a combination of wind and cold air
14. Classifies tornadoes according to their destruction and estimated wind speed on a scale ranging from EF0 to EF5
15. violent thunderstorms that can spawn tornadoes
16. A dome of water that sweeps across the coast where a hurricane lands
17. A prolonged period of extensively hot weather.
18. a branch channel of positively charged ions that rushes upward from the ground to meet the stepped leader
19. Type of thunderstorm in which air rises because of unequal heating of Earth's surface within a single air mass and is most common during the afternoon and evening

1. Classifies hurricanes according to wind speed on a scale ranging from Category 1 to Category 5
2. local air-mass thunderstorm that commonly occurs along a coastal area because land and water store and release thermal energy differently
3. The channel of partially charged air; the breakdown in charges in between positive and negative regions
4. thunderstorms caused by advancing cold fronts.
6. Calm center of a tropical cyclone.
7. a wave of unusually cold weather
9. occurs when an air mass rises from orographic lifting, which involves air moving up the side of a mountain
