Questions and Answers

If a parcel of air is described as having a higher density than its surroundings, what can be inferred about the air's temperature?

  • The air is the same temperature as its surroundings
  • The air is warmer than its surroundings.
  • The air is colder than its surroundings. (correct)
  • The temperature is irrelevant to the density comparison.
  • What type of weather is most closely associated with an occluded front?

  • Heavy precipitation and strong winds. (correct)
  • Clear skies and calm conditions.
  • Slowly changing conditions and light showers.
  • Extended periods of consistent, moderate temperature.
  • Which of the following best describes the general direction that a cold front symbol is considered to indicate?

  • The direction of the low-pressure zone.
  • The direction of the high-altitude winds.
  • The direction the front is moving from.
  • The direction the front is moving towards. (correct)

    Cold Front

    A front where cold air mass pushes up a warm air mass.

    Warm Front

    A front where warm air mass slowly pushes up a cold air mass.

    Polar Winds

    Winds closer to the poles are colder and denser, leading to higher pressure.

    Equatorial Winds

    Winds closer to the equator are warmer and less dense, leading to lower pressure.

    Study Notes

    Atmospheric Layers & Properties

    • Letters represent different atmospheric layers.
    • Lower pressure is found in a specific layer.
    • Lower temperature is found in a specific atmospheric layer.
    • Higher density is found in a specific atmospheric layer.
    • Higher temperature is found in a specific atmospheric layer.
    • Coldest layer is a specific atmospheric layer.
    • Ozone layer is in a specific atmospheric layer.
    • All weather occurs in a specific atmospheric layer.
    • Hottest layer is a specific atmospheric layer.

    Wind Types

    • Oceanic winds occur from the ocean/sea.
    • Land winds occur from land areas.
    • Winds closer to the poles are a specific type.
    • Winds near the equator (middle of the Earth) are a specific type.
    • The global wind system significantly impacts weather conditions in places like Pennsylvania (PA).

    Fronts & Weather

    • Different types of fronts (cP pushing up mT, warm, cold, occluded, stationary) exist.
    • Warm air has lower density than cool air.
    • Cold air is denser than warm air.
    • Specific weather-related symbols denote different front types.
    • Cold fronts produce specific weather conditions.
    • Warm fronts produce specific weather conditions.
    • Occluded fronts produce specific weather conditions.
    • Stationary fronts produce specific weather conditions.
    • Front symbols show movement direction for weather prediction.
