  1. Warm Up 1. Which front moves through an area faster: Cold or Warm? 2. Which property of this front explains this rate? 3. What type of snow storm would a warm front likely bring? What is the moisture content and temperature of an air mass that formed in: 4. Maritime Polar - mP 5. Continental Arctic - cA Hint: wet or dry? cold or warm?

  2. Agenda & Objective SWBAT describe the formation of cyclonic storms • Objective • Weather Tracker • Yesterdays Exit Ticket • Textbook search • Venn Diagram • STORM CHASERS • RAGING PLANET Video • Independent Work Time • Unit 8 Exit Ticket • Unit 8 Study Guide • -Due FRI 1/9 • Tutoring @ thurs 2:30

  3. Warm Up 1. Which front moves through an area faster: Cold or Warm? 2. Which property of this front explains this rate? 3. If a warm front occurs in the winter, what type of snow storm would it likely bring? What is the moisture content and temperature of an air mass that formed in: (hint: wet or dry? cold or warm?) 4. Maritime Polar - mP 5. Continental Arctic - cA

  4. Warm Up 1. Which front moves through an area faster: Cold or Warm? Cold front because warm air is easy to push 2. Which property of this front explains this speed? Cold is the “boss” = dense Warm air is less dense So the moving cold air controls what the warm air does

  5. Warm Up 1. Which front moves through an area faster: Cold or Warm? 2. Which property of this front explains this rate? 3. If a warm front occurs in the winter, what type of snow storm would it likely bring? What is the moisture content and temperature of an air mass that formed in: (hint: wet or dry? cold or warm?) 4. Maritime Polar - mP 5. Continental Arctic - cA

  6. Warm Up 3. If a warm front occurs in the winter, what type of snow storm would it likely bring? Light snow & long duration – same effect as rain, its just a cooler temp.

  7. Warm Up What is the moisture content and temperature of an air mass that formed in: 4. Maritime Polar - mP 5. Continental Arctic - cA

  8. Warm Up What is the moisture content and temperature of an air mass that formed in: 4. Maritime Polar - mP moisture = wet temp = cold 5. Continental Arctic - cA

  9. Warm Up What is the moisture content and temperature of an air mass that formed in: 4. Maritime Polar - mP moisture = wet temp = cold 5. Continental Arctic - cA moisture = dry temp = cold

  10. Where would the 6 different air masses originate? mA, mT, mP, cP, cT, cA mP mP cA cP mT cT mT

  11. Let’s update our Weather Tracker Sheet!Inches of mercury and centimeters of mercury measure how high the pressure pushes the mercury in a barometer. http://www.intellicast.com/Local/Weather.aspx?location=USN0121

  12. 2.5 Understand the structure of and processes within our atmosphere. 2.5.1 Summarize the structure and composition of our atmosphere. Learning through textbook comprehension importance of yellow atmosphere assignment

  13. 2.5.2 Explain the formation of typical air masses and the weather systems that result from air mass interactions. Learning via instruction & notes Practice through questions & exit ticket Explain how air masses move (pressure differentials).  Explain how interactions of air masses form frontal boundaries, clouds, and affect wind patterns.

  14. 2.5.3 Explain how cyclonic storms form based on the interaction of air masses. Write three key words from the following: Explain factors that affect air density and understand their influence on winds, air masses, fronts and storm systems. 􏰁Use data for explanations and provide evidence of various air mass interactions. Address precautions for severe cyclonic storms to preserve life and property.

  15. History of Katrina • http://www.youtube.com/watch?v=7unlPvNxLLA

  16. Hurricane Katrina Damage

  17. HURRICANE KATRINA…7 years later • http://projects.usatoday.com/news/katrina/#/prologue/the-storm/the-storm

  18. Hurricane and Tornado SEARCH • You may choose one partner & move once • Textbook pages: 573-577 • everything can be found within these pages. • Stay seated, Talk quietly, Face forward • If you finish early, work on 1. venn diagram 2. unit 8 study guide

  19. Transition with a partner • 90 seconds to do the following: • Partner • Textbook • Seat

  20. Hurricanes Tornadoes

  21. Comparing and Contrasting Tornadoes and Hurricanes • Spinning systems of low pressure • High speed winds

  22. What is a Tornado?

  23. How Do Tornadoes Form? Warm, humid air collides with cold, dry air The warm air rises up through the cold air creating an updraft because of a LOW PRESSURE SYSTEM If this updraft begins spinning, it can turn into a tornado

  24. Damage Caused by Tornadoes Extremely high winds can tear buildings apart, slip cars, and even suck the water out of a riverbed Most likely during the months of April, May & June

  25. Wait…how exactly does it form? • http://news.bbc.co.uk/2/hi/science/nature/7533941.stm • Animation

  26. Check point #1 • What type of pressure systems are tornadoes associated with? • What causes the most damage during a tornado? • What is the intensity ranking for tornadoes?

  27. Hurricane

  28. FAST FACT • In the Atlantic and Northeast Pacific, the term “hurricane” is used. • The same type of disturbance in the Northwest Pacific is called a “typhoon” • In the South Pacific and Indian Ocean “cyclones” occur

  29. Damage Caused by Hurricanes Most from the storm surge and flooding!! Most likely to occur in Late Summer to Early Fall

  30. FAST FACT The word “hurricane” comes from the Taino Native American word, Hurucane, meaning “evil spirt of the wind.” The first time anyone flew into a hurricane happened in 1943 in the middle of WWII.

  31. Wait…how exactly does it form? • http://news.bbc.co.uk/2/hi/science/nature/7533909.stm

  32. Checkpoint #2 • What produces the most damage during a hurricane? • What must be true of ocean temperatures in order for a strong hurricane to form? • What is the intensity ranking scale for hurricanes? • What happens when a hurricane hits land? • What is the eye of the hurricane and what are the winds like IN the eye of the storm?

  33. Raging Planet: Hurricanes 10:35-19:00 25:46-31:15 Storm Chasers, Take 2! Answer the questions and fill in the blanks on the worksheet provided while you watch

  34. Independent Practice Apply your knowledge & show learning Stay in assigned seat, talking quietly, responsible phones • If you finish early, work on: 1. unit 8 study guide 2. yellow atmosphere sheet 3. late work

  35. Preparation for End of Class • Clear desk • Unit 8 Study Guide is due FRI 1/9 • Guided Notes = study tool so keep in BINDER

  36. Unit 8 Exit Ticket • Return to Assigned seat • Clear desk • Only need something to write with

  37. Testing Expectations & DIRECTIONS • Clear your desk • Place this SYMBOL in box • No talking at ALL When finished, flip paper over @ the bell hand in – 1. scantron to exit ticket box 2. question sheet to box

  38. Preparation for End of Class • When you are FINISHED • Hand in the following near textbooks: • Scantron • Pen • Question Sheet • Return to your seat and work on Knowledge Café independently • Knowledge Café is due THURS 5/15

  39. 1. What type of air pressure system is associated with hurricanes and tornadoes? 2. What is the intensity ranking scale for hurricanes? 3. What is a key difference between tornadoes and hurricanes? 4. What produces the most damage during a hurricane? 5. What produces the most damage during a tornado?
