5 Matching questions

  1. What is the Jet Stream?
  2. Thermal equator?
  3. What do high pressure cells tend to do?
  4. Explain air pressure tendency.
  5. What are doldrums?
  1. a 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.
  2. b 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.
  3. c An isoline connecting all points of highest mean temperature.
  4. d
    The Jet Stream is a relatively narrow corridor of very strong winds near the tropopause.
  5. e High pressure cells tend to descend and diverge.

5 Multiple choice questions

  1. 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.
  2. The four factors that affect atmospheric circulation are as follows: the Coriolis Effect, gravity, friction forces, and changes in air pressure.
  3. Equal pressure.
  4. The wind direction is always reported as the direction from which the wind is blowing. Winds which blow from the west, for example, are westerlies. They blow towards the east. Winds which blow from the south are called southerlies. They blow towards the north.
  5. Low pressure cells tend to ascend and converge.

5 True/False questions

  1. Isotach?Equal wind speed.

          

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

          

  3. What are the rules for isopleths?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.

          

  4. 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.

          

  5. What are the four major pressure areas on Earth?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.
