Weather Study Guide Part 2
1.______is large body of air when temperature and moisture content are similar throughout. / Air Masses2.The region over which air masses form. / Source Regions
3. Complete the chart and write description for each air mass.
A-Continental Polar (cP)- Cold and Dry-forms over land
B-Continental Tropical (cT)- Warm and Dry-forms over land
C-Maritime Tropical (mT)- Moist(Wet/Humid) and warm- forms over warm water
D- Maritime Polar (mP)- Moist (Wet/Humid) and Cold-forms over cold water /
4. Which type of air mass affects the weather in Georgia? / Maritime Tropical (mT)
5.The boundary between air masses of different densities and usually different temperatures. This is where weather occurs! / Front
6. Diagram and explain how a cold front forms. Include the weather that results from the front and the symbol. /
• Cold air mass meets a warm air mass and pushes the warm air mass out of its way.
• Bring thunderstorms, rain or snow.
• Most tornadoes develop from thunderstorms on the edge of a cold front.
• Cold front followed by cooler drier air.
7. Diagram and explain how a warm front forms. Include the weather that results from the front and the symbol. /
• Warm air mass meets a cold air mass and pushes the cold air mass out of the way.
• Brings drizzly precipitation.
• Clouds, Storms, and rain accompany
• Followed by clear warm weather
8. Diagram and explain how an occluded front forms. Include the weather that results from the front and the symbol.
/
• Warm air caught between two cold air masses.
• Brings cool temperatures with large amounts of rain or snow
•
9. Diagram and explain how an stationary front forms. Include the weather that results from the front and the symbol.
/ · Cold air meets warm air.
• Not enough force to move either front.
• Many days of cloudy, wet weather.
• Unlike a fast-moving front, Stationary fronts often bring several days of cloudy, wet weather that can last a week or more.
10. What type of weather can cause property damage and sometimes death? / Severe Weather (Thunderstorms, Flooding, Tornadoes, Hurricanes)
11. ______are usually brief, heavy storm that consists of rain, strong winds, lightning, and thunder / Thunderstorm
12. ______an electric discharge that takes place between two oppositely charged surfaces, such as between a cloud and the ground, between two clouds, or between two parts of the same cloud / Lightning
13. The sound caused by the rapid expansion of air along an electrical strike. / Thunder
14. What is a tornado? / A destructive, rotating column of low pressure air that has very high wind speeds, is visible as a funnel shaped cloud, and touches the ground
15. What is a funnel cloud? / A spinning column of air at the bottom of a cumulonimbus cloud
16. ______a severe storm that develops over tropical oceans and whose strong winds of more than 120 km/h spiral in toward the intensely low-pressure storm center / Hurricane
17. What is the most powerful storm on Earth? / Hurricane
18. A hurricane begins as a group of ______moving over tropical ocean waters. / Thunderstorms
19. A hurricane gets it energy from the ______of water vapor. / Condensation of warm moist air
20. Hurricanes continue to grow as long as it is over its source of ______, ______air. / Warm, moist air
21. When the hurricane moves into ______waters or over ______, it begins to die because it has lost its source of energy. / Cooler or land
22. ______a core of warm, relatively calm air with low pressure and light winds / Eye
23. Thunderstorms, Tornados, and Hurricanes form at …. / Low pressure systems
