Essay Questions

Coriolis Effect:

1. Essay/Demonstration Question. Discuss and show how, using a series of diagrams or models, the Coriolis effect has the opposite sense of motion in the Southern Hemisphere compared to the Northern Hemisphere.
 
 
 
 
 
 
 
 
 
 
 

2. Essay/Demonstration Question. Demonstrate that the Coriolis effect in either hemisphere holds true no matter which direction an air mass is moving: north, south, east or west.
 
 
 
 
 
 
 
 



Atmosphere Global Circulation

3. Essay/Demonstration: Find a series of satellite images or a montage of such images and illustrate and discuss all elements of the global circulation system that you can see. Discuss why the circulation patterns are more "uniform" or smooth in Southern Hemisphere, compared to the Northern Hemisphere.
 
 
 
 
 
 
 
 
 
 

4. Essay/Demonstration: Locate and download an upper level chart, such as the 500-mb chart, and a synchronous surface satellite image showing cloud patterns. Annotate and illustrate the chart and satellite image to show all elements of the global circulation system that you can see. Compare and contrast the two views, and discuss why the patterns aloft appear to be more "Uniform" or "smoother" that the patterns you see at the surface.
 
 
 
 
 
 

 



Atmosphere Weather Tracking and Interpretation

5. Essay/Demonstration: Use appropriate satellite images to locate a cold front or a warm front near your location. Find two stations on opposite sides of the front, and obtain the vertical soundings for these stations. Discuss if the data you obtain is consistent with what you would expect for two sites on opposite sides of a front. Develop a mathematical model that will predict the temperature at any elevation for both sides of the front. Discuss the usefulness and accuracy of your model.
 
 
 
 
 
 
 
 
 
 
 
 
 

 
 

6. Essay/Demonstration: Research and select an historical hurricane from the Caribbean or Pacific. Find one that has an abundance of archived images, locate the images, and assemble a sequence of images that shows the entire development and dissipation of the storm. Write an essay, illustrated with your images, which addresses the origin, development, and disposition of hurricanes, their energy, and their moisture.
 
 
 
 
 
 
 
 
 

7. Essay/Demonstration: Locate a weather system (a cold front, a tropical storm, a winter storm, a rain storm, et cetera) that is apparently heading towards your location. Try to locate one that is still some time and distance away. Examine all of the information you can find on the internet in terms of satellite images, soundings and so on, and begin making a series of predictions about how the system is going to affect you and your location. Use the weather prediction from a local weather caster or the local newspaper as a model. As the system gets closer to you in time and space, compare the accuracy of your forecasts with those made by the professionals. Discuss how and why your predictions are accurate or inaccurate. Are you more accurate the closer the system is to you in time? What sorts of information would you need to make a more accurate prediction?
