Presentation Transcript

  1. DO NOW! • What are the 4 layers of the atmosphere and on what basis are they divided? • In which layers does temperature increase/decrease with altitude? • Which type of air is more dense, warm air or cold air? • Complete the boxes below by drawing particles for the different air temperatures using your answer from #1 • If you are fighting on the frontline of battle, where are you? Cold Air Warm Air

  2. Big Goal • We will become informed, global citizens, prepared to excel at the college level • We will be able to independently score 80% or Higheron all assessments

  3. Objective • We will be able to describe the weather patterns associated with warm and cold fronts

  4. Agenda • Do Now! • Air Front Guided Notes & Questions • Air Front Foldable • Weather Word Search + Definitions • Missing Assignments • Exit Ticket

  5. Quote of the Day “The difference between a successful person and others is not a lack of strength, not a lack of knowledge, but a lack of will.” ~Vincent T. Lombardi

  6. Air Masses Notes • Air mass: • a large body of air with similar temperatures and amount of moisture • As it moves, the characteristics of the air mass change and so does the weather in the area

  7. Air Masses • Moisture of source • Continental: formed over land (DRY) • Maritime: formed over water (HUMID) • Temperature of source • Polar: formed over polar area (COLD) • Tropical: formed over tropical area (WARM)

  8. Where would the 4 different air masses originate? mT, mP, cP, cT

  9. Fronts • Form when two air masses meet • They are the boundary that separates the two air masses • There are 4 types of fronts…

  10. WHY YOU BE FRONTIN’?! • Use your textbook to complete your worksheet: • Warm Fronts: pg. 565 • Cold Fronts: pg. 566 • Stationary Fronts: pg. 566 • Occluded Fronts: pg. 567

  11. Warm Fronts • Warm air mass meets and rises above cold air mass • Associated with slow and steady rain, followed by hot, humid weather • gentle slope

  12. Cold Fronts • Cold air masses overtake and pushes under warm air mass forms faster • Heavy rains and violent thunderstorms, followed by fair, cool weather • Steeper slope

  13. Stationary Fronts • Front does not move b/c air flows parallel to front line • Gentle to moderate precipitation

  14. Whats the difference between a warm front and a cold front? • Which forms faster, a warm front or a cold front?

  15. Occluded Fronts • Cold fronts move faster than warm fronts they can catch up to and overtake a warm front, wedging the warm air upward • Complex; Heavy rains followed by light precipitation for several days

  16. Exit Ticket __1. What type of front occurs when warm air moves into an area where cooler air was? a. warm front c. stationary front b. occluded front d. cold front __2. When two air masses meet, what is going to occur depending on air temperature? a. cooler air will move on top of warm air b. warm and cool air will flow evenly throughout c. warm air will move on top of cooler air d. medium temperature air will occur __3. During a warm front, what type of weather are you most likely to experience? a. Clear, sunny skies c. Steady, but light precipitation b. High winds d. Thunderstorms

  17. Exit Ticket __4. If a cold front just passed through Charlotte, what type of weather was experienced while the cold front was occurring? a. Clear, sunny skies c. No precipitation but high winds b. Thunderstorms d. Light precipitation for a few days 5. Using the picture below, what type of front is occurring and what type of weather will be experienced in the area? Front: ___________________________________ Weather: _________________________________
