Weather Forecasting

3. rotating funnel cloud with extremely high winds that grows downward from a cumulonimbus cloud
6. large storm with high winds and heavy rains that forms from a tropical cyclone
7. line on a weather map that connects points with the same air pressure
9. boundary that forms where two air masses with different characteristics meet
10. front that forms when a cold front overtakes a warm front, so a warm air mass is trapped between two cold air masses
11. cluster of water droplets or ice crystals that have condensed in the atmosphere
12. line on a weather map that connects points with the same temperature
15. weather instrument that measures air pressure
17. large body of air with about the same temperature and humidity throughout (2 words)
19. front that forms at the boundary between air masses that are stalled in the same place
20. storm caused by upwelling air and characterized by cumulonimbus clouds, lightning, and thunder

1. large snowstorm with cold temperatures, high winds, and reduced visibility because of wind-blown snow
2. instrument that measures temperature
4. group of instruments that measure atmospheric characteristics, such as temperature and humidity, as they move through the air
5. wind system that rotates around a high-pressure center
8. loud noise produced by lightning because the discharge of electricity causes the air to heat and expand so quickly that it explodes
13. huge discharge of static electricity that typically occurs during a thunderstorm
14. line on a weather map that connects points with the same wind speed
16. radio detection and ranging device that emits radio waves and receives them after they reflect from the nearest surface, including water droplets in the atmosphere
18. wind system that rotates around a low-pressure center
