Chapter 20: Storms and Weather Prediction

4. A strong cyclonic storm with winds at least 63 km/h
6. A warm air mass that originates that originates in the tropics
9. an immensive cyclonic storm that forms over tropical or subtropical oceans
11. a destructive localized rapidly rotating windstorm forming a tunnel
12. A symbolic representation of data from a weather station on a weather map each number and symbol and their locations in the model provide specific weather information
13. The lifting of a warm air mass above above a cool air mass acting as a wedge
14. A weather map that presents a summary or synopsis of weather data for a given time frame there are four synoptics weather maps the Surface Weather ,ap the highest and lowest temperatures map the precipitation areas and amounts maps and the 500 Millibar Height Contours map.
18. A cool or cold air mass that originates over upper latitudes
20. A higher than normal local sea level caused by seawater flowing towards the lower air pressure under a hurricane
21. The boundary where at least two different air masses meet

1. A frigid air mass that originates over the poles
2. A low humidity air mass that originates over land
3. A high humidity air mass that originates over the oceans
5. The upward movement of air masses as they flow over mountains
7. A huge body of air in the troposphere with similar temperature and humidity throughout
8. a rainstorm that produces lighting Thunderstorms may include hail, bursts of strong wind and even tornadoes
10. the low pressure center of a hurricane containing relatively clear calm rising air
15. A sever weather disturbance involving high winds heavy precipitation and other conditions
16. The lifting of air when horizontal air currents from opposite directions collide and rise into the atmosphere
17. A storm that brings heavy snow or sleet high winds or unusually cold weather
19. An atmospheric electrical discharge that occurs either between clouds or between cloud and the ground
