  1. A secondary discontinuity when crossing a front is what?
    A temperature change
  2. What type of front produces the most hazardous weather?
    Fast moving cold front
  3. How far in front of a front can squall lines form?
    50-300 miles
  4. Stationary fronts develop when the cold and warm fronts slow to what speed?
    Less than 5 knots
  5. What is an occlusion?
    When a fast moving cold front totally lifts a warm front off of the ground.
  6. What forms with the temperature and dew point are equal?
    Clouds and fog
  7. On clear nights the heat of the earth quickly radiates off into space. As the ground cools off the air just above it fog is formed. What is this kind of fog called?
    Radiation fog
  8. When warm air flows over a cold surface fog can form. What is this type of fog called?
    Advection Fog
  9. When air is forced to rise up a mountain slope fog can form. What kind of fog is this?
    Upslope fog
  10. Cold air from land moving over warmer water can cause what type of fog?
    Steam Fog
  11. What kind of clouds are thunderclouds?
    Cumulonimbus
  12. What is the first stage of a thunderstorm?
    Cumulus stage which has continuous updrafts
  13. What is the second stage of the thunderstorm?
    Mature stage is when the rain begins to fall. It is the MOST DANGEROUS and is characterized by a cauliflower shape.
  14. What is the third stage of a thunderstorm?
    The dissipating stage characterized by the anvil shaped cloud.
  15. What severe wind conditions are associated with thunderstorms?
    Severe up and down drafts, wind sheer.
  16. Where are the most intense thunderstorms found?
    In squall lines.
  17. Gust fronts lead what type of storm?
    Thunderstorms
  18. What is a reasonable safe distance to stay away from thunderstorms?
    20 miles
  19. What weather convective activity causes both horizontal and vertical wind sheer?
    Microburst
  20. What visual clue is there for a microburst when there is little or no precipitation?
    A ring of blowing dust.
  21. Do microbursts happen singularly or in groups?
    multiple microburst typically happen
  22. A weather factor that causes a momentary change in altitude and or attitude is called what?
    Light turbulence
  23. Large and abrupt changes in altitude and or attitude, along with large variations in airspeed is called what?
    Severe turbulence
  24. Moderate turbulence is similar but has greater intensity than what?
    Light turbulence
  25. What is necessary for ice to form on an airplance?
    Visible moisture.
