Weather Review

2. an _______ front forms when a warm air mass gets caught between two cold air masses. Can cause strong winds and heavy precipitation.
6. any form of liquid that falls from the sky to the ground
9. water gains thermal energy, turns into vapor, and rises into the air
11. air masses that form near the poles; cold air masses
12. lines on a weather map that represent changes in air pressure
15. this type of system brings overcast, cloudy skies with possible precipitation (lousy weather)
17. a large body of air with a consistent temperature and moisture content
20. the boundary between air masses of different densities
21. water does this when the temperature is 32 degrees or lower
22. tool for measuring wind speed
23. the amount of water vapor in the air
24. the condition of the atmosphere at a specific place and time

1. tool used to measure air pressure
3. temperature at which the atmosphere cannot hold anymore water vapor
4. the average or typical weather condition of a region year after year
5. a ______ front forms when a cold air masses pushes under a warm air mass, causes the warm air to rise quickly. Typically causes thunderstorms followed by cooler temperatures
7. water vapor cools and changes back into liquid form
8. determines whether precipitation will fall as rain or snow
10. air masses that form near the equator; warm air masses
13. a ______ front forms when a warm air mass slides over a cold air mass. Typically causes gentle precipitation followed by warmer temperatures
14. air masses that form over land; dry air masses
16. this type of system brings fair weather and clear skies (happy weather)
18. a _______ front forms when a warm and cold air mass meet and neither has the force to push the other out of the way. Can cause steady rain for several days.
19. air masses that form over water; wet/moist air masses
