  1. Fronts

  2. When 2 ____________ air masses meet, density differences usually keep them separate--________________________ • The boundary between air masses is called a_______________

  3. For a front to form, one air mass must __________________________________ • The kind of front depends on ___________ ___________________________________

  4. Cold Front • A ____ air mass overtakes a _____ air mass • The moving cold air lifts the warm air • If the warm air is moist, _______________.

  5. A line of heavy storms called a ______________ may occur ahead of a fast-moving cold front

  6. A slow-moving cold front produces ___________________________________

  7. Warm Front • Warm air mass overtakes a cooler air mass • ___________________________________

  8. The slope of a warm front is _________, so clouds may extend far ahead of the front • Warm fronts generally produce __________ _____________________________________

  9. Stationary Front • Two air masses move ____________to the front between them • The front ______________________ • These type of conditions can last for days, producing nothing but Altocumulus clouds. Temperatures remain stagnant and winds are gentle to nil.

  10. Occluded Front • A fast-moving cold front overtakes a slow-moving warm front and ___________________________ ________________________________________ • The cold air comes in contact with cool air beneath the warm air • The warm air is completely cut off, or _________ from the ground • Weather is similar to that produced by a warm front

  11. Wave Cyclones: Low-pressure Storm Centers • Winds blow in ________________ circular paths spiraling upward around the __________________region at the center • ___________________________________ • b/c rising air allows for condensation

  12. Anticyclones: High-pressure Centers • The air sinks and flows ________________ outward from a center of _______________ • Bring _________ weather • Sinking air does not promote cloud formation ***the sinking air could cause a temperature inversion
