  43. What is the dew point?
    The temperature at which air is completely saturated.
  44. What is a front?
    boundary between 2 air masses.
  45. Describe a warm front
    • Warm air is replacing cold air.
    • Poor visibility
    • Moves at slow speed.
    • Slope of a warm front is very gradual and may extend up over cool air for several hundred miles ahead of the front.
  46. Describe a cold front
    • Cold air is moving to displace warmer air
    • Dense and stable air moves along surface and forces less dense, warm air upward.
    • Showers and poor visibility
  47. Describe a stationary front
    • No movement
    • Opposing forces of two masses are relatively balanced
  48. Describe an Occluded front
    • Cold fronts are usually fast moving ad often catch up to and merge w/ a slower moving warm front
    • When cold and warm fronts merge they create an occluded front (temp in each front influences which type of front and weather are created.
  49. How do Cold front occlusions develop?
    Fast-moving cold front is colder than the air ahead of the slow-moving warm front
  50. How is a warm front occlusion develop?
    The air ahead of the slow-moving warm front is colder than the air within the fast-moving
  51. What conditions are required for thunderstorms to form?
    • Unstable conditions
    • a lifting force
    • high moisture levels
  52. What are the stages and their characteristics of thunderstorms?
    • Cumulus - lifting action initiates the vertical movement of air, continuous updrafts
    • Mature - greatest intensity and precipitation begins
    • Dissipating - downdrafts that eventually weaken the storm
  53. What often exist in cumulonimbus clouds?
    • Severe turbulence
    • lightning
    • hail
    • tornadoes
