  2. Question # 1 • What happens to air as the lower layers are warmed? • The air rises

  3. Question # 2 • What’s an air mass? • A large body of air throughout which temperature and moisture content are similar

  4. Question # 3 • Name the four types of air masses and give their symbols. • Continental polar (cP) • Continental tropical (cT) • Maritime polar (mP) • Maritime tropical (mT)

  5. Question # 4 • If a tornado were to touch down, what’s the path it would take? • Not predictable

  6. Question # 5 • What’s an anticyclone? • A weather event in which the air sinks and flows outward from a center of high pressure, and that brings dry weather.

  7. Question # 6 • Why would a scientist want to study upper atmospheric conditions? • In order to track global weather patterns

  8. Question # 7 • What do the H’s and L’s represent? • Air pressure centers

  9. Question # 8 • What’s a midlatitude cyclone? • When a bend forms in a cold front, it begins the process of creating an area of low pressure with rotating wind that moves toward the rising air of the central low-pressure region

  10. Question # 9 • What happens with the information that weather centers collect? • They exchange them with other centers

  11. Question # 10 • How is the information conveyed on a weather map? • Colors and symbols

  12. Question # 11 • What are the characteristics of a warm front? • Produce precipitation over a large area and are sometimes violent

  13. Question # 12 • What’s a radiosonde? • An instrument package that is carried high into the atmosphere by a helium-filled balloon to measure relative humidity, air pressure, and air temperature

  14. Question # 13 • What’s a front that forms when a cold air mass overtakes a warm air mass and lifts the warm air mass off the ground and over another air mass? • A cold front

  15. Question # 14 • Fill in the chart below Polar regions in Canada Cold & Dry Warm & Dry U.S. Southwest Polar Pacific & Polar Atlantic Cold & Moist Tropical Pacific & Tropical Atlantic Warm & Moist

  16. Question # 15 • What’s a hurricane? • A severe storm that develops over tropical oceans, whose strong winds spiral in toward the low-pressure storm center

  17. Question # 16 • A destructive, rotating, funnel-shaped column of air with high wind speeds is known as what? • A tornado

  18. Question # 17 • What’s a brief, heavy storm with rain, wind, lightning, and thunder called? • A thunderstorm

  19. Question # 18 • What’s a front that forms when a cold air mass overtakes a warm air mass and lifts the warm air mass off the ground and over another air mass? • Occluded front

  20. Question # 19 • What’s a stationary front? • A front of air masses that moves either very slowly or not at all.

  21. Question # 20 • What causes the different air pressures on Earth? • The unequal heating of the Earth’s surface.
