5 Matching questions

  1. Isobar?
  2. What are the rules for isopleths?
  3. Describe the Polar High Pressure area.
  4. What does tertiary circulation in the atmosphere entail?
  5. What are the four major pressure areas on Earth?
  1. a
    The four major pressure areas on Earth are the Equatorial Low (warm, wet 10 degrees N/S), Polar High (cold, dry 90 N/S), Subtropical High (hot, dry 20-35 N/S), and the Subpolar Low (cool, wet 60 N/S).
  2. b The Polar High Pressure consists of polar easterlies and the Antarctic High pressure area.
  3. c 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.
  4. d Equal pressure.
  5. e Isopleths must be continuous and cannot intersect other isopleths. All values above the isopleth should be on one side of the line and all values below an isopleth should be on the other side of the isopleth. The position of the isopleth should be interpolated in between points of known data. They should choose a contour interval and start at an area of high or low values.

5 Multiple choice questions

  1. Equal elevation.
  2. Trade Winds blow out of the equator side of the anticyclones. In the Northern Hemisphere, they are the Northeasterly Trade Winds. They are the most persistent winds in the world, blowing in the same direction about 80% of the time.
  3. Primary circulation entails global circulation - the mass movement of air all over the globe.
  4. 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.
  5. Air pressure tendency is important, along with the air pressure reading on a barometer. Falling air pressure, which corresponds to a decrease in the length of mercury in the column on a mercurial barometer, generally indicates stormy weather.

5 True/False questions

  1. Describe the Coriolis Effect.
    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.

          

  2. Describe the Subpolar Low Pressure area.The Subpolar Low Pressure area consists of the Aleutian Low, the Icelandic Low, and the Polar Front.

          

  3. Thermal equator?An isoline connecting all points of highest mean temperature.

          

  4. What four factors affect atmospheric circulation?Isopleths must be continuous and cannot intersect other isopleths. All values above the isopleth should be on one side of the line and all values below an isopleth should be on the other side of the isopleth. The position of the isopleth should be interpolated in between points of known data. They should choose a contour interval and start at an area of high or low values.

          

  5. Describe friction forces.
    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.
