  1. Describe the Polar High Pressure area.
  2. Describe the Coriolis Effect.
  3. How is air pressure measured?
  4. What four factors affect atmospheric circulation?
  5. Describe land-sea breezes.
  1. a
    Land-sea breezes are driven by the thermal inertia of water. When land and sea receive the same amount of insolation, the land heats up faster than the water. This temperature gradient causes winds to blow. At night, radiational cooling cools the land faster than the water so that the temperature gradient makes a wind blow from land to sea. These breezes also occur for large bodies of water, such as the Great Lakes.
  2. b
    The Coriolis Effect deflects winds fro ma straight line in relation to the Earth's rotating surface. Earth's rotation adds the Coriolis Effects and a "twist" to air movements. In the Northern Hemisphere, winds are deflected to the right, or the east. In the Southern Hemisphere, winds are deflected to the left, or the west.
  3. c A barometer can measure changes in air pressure. The two types of barometers are the mercurial barometer, which is more accurate but less easily transportable, and the aneroid barometer, which is less accurate but more portable.
  4. d The Polar High Pressure consists of polar easterlies and the Antarctic High pressure area.
  5. e The four factors that affect atmospheric circulation are as follows: the Coriolis Effect, gravity, friction forces, and changes in air pressure.

5 Multiple Choice Questions

  1. The Equatorial Low Pressure area occurs along the Intertropical Convergence Zone (ITCZ) and is the area where the Trade Winds and doldrums occur.
  2. Primary circulation entails global circulation - the mass movement of air all over the globe.
  3. Doldrums refers to a broad east-west belt of light winds that occur along the equator where the Trade Winds from the northern and southern hemispheres converge.
  4. Equal elevation.
  5. Equal wind speed.

5 True/False Questions

  1. What are Trade Winds?Doldrums refers to a broad east-west belt of light winds that occur along the equator where the Trade Winds from the northern and southern hemispheres converge.

          

  2. What is the Jet Stream?The ITCZ stands for the Intertropical Convergence Zone, which is the area along the equator where a discontinuous series of thunderstorms occurs, due to the uplift caused by the convergence of winds and solar heating of the ground along the equator.

          

  3. What do low pressure cells tend to do?Low pressure cells tend to ascend and converge.

          

  4. Isobar?Equal wind speed.

          

  5. What does tertiary circulation in the atmosphere entail?Tertiary circulation is the movement of local high and low pressure cells, and parcels of air will cause local weather patterns, such as the weather patterns of a coastal city that is influenced by the body of water nearby.
