Across
- 3. A body of circulating air with low pressure at its center and higher pressure outside the system. It brings clouds and precipitation.
- 4. Air masses can be classified by this factor (and moisture).
- 8. A boundary where two air masses of different temperature and moisture content meet and weather occurs.
- 10. This front forms when a cold air mass meets a warm air mass but neither has the force to move the other. The weather is often cloudy along the front line and rain or snow often falls especially if the front is an area of low atmospheric pressure.
- 11. The state of the atmosphere at a place and time like heat, dryness, sunshine, wind, and or rain over a short period of time.
- 13. Cold air moves under warm air forcing warm air up.
- 14. Masses formed over water.
- 15. Warm air masses.
- 16. A large body of circulating air with high pressure at its center and lower pressure outside the system. It brings sunshine and good weather.
Down
- 1. Masses formed over land.
- 2. This front forms when the warm air mass is caught between two cool air masses. The warm air mass rises as the cool air masses push and meet the middle. The temperature drops as the warm air mass is occluded.
- 5. A layer of the Earth's atmosphere that weather can occur.
- 6. What moves air masses in the Continental US (Also can be prevailing westerlies)>
- 7. These fronts move slowly and bring warm humid air. At constant atmospheric pressure, warm air is less dense than cold air, so it tends to override rather than displace the cold air.
- 9. Cold air masses.
- 12. A body of air with a relatively constant temperature and moisture content over a significant altitude. Air masses typically cover hundreds, thousands, millions of square kilometers.
