Homework 6

This assignment is due on Wednesday, October 26 at the beginning of the lecture.

 

  1. How are cold fronts different from stationary fronts? How are cold fronts different from drylines? How are cold fronts and drylines alike?

     

  2. Name three types of fronts that are examples of the "polar front". Why are the other two types of fronts NOT examples of the "polar front"?

     

  3. Where would you look for rain associated with a warm front--north of the front or south of the front? Why?

     

  4. Which kind of front is more steeply sloped--cold front or warm front? Which kind of front moves more quickly--cold front or warm front? Which kind of front is associated with stratus clouds--cold front or warm front?

     

  5. Consider the following meteogram, which is from St. Louis during a recent 24 hour period:

     
    • At what time did a front pass through St. Louis?
    • What kind of front do you think it is? What factors lead you to this conclusion?
    • Describe how the weather changed as this front passed through. Be sure to mention changes in temperature, winds, dewpoint and pressure.

     

  6. Consider the following meteogram, which is from Charleston, South Carolina during a recent 24 hour period. (The temperature, dewpoint and pressure curves are in the same place as they were on the previous diagram--I just didn't take the time to label everything again by hand. Use the diagram from St. Louis to remind yourself about which curve is which.)

     
    • At what time did a front pass through Charleston?
    • What kind of front do you think it is? What factors lead you to this conclusion?
    • Describe how the weather changed as this front passed through. Be sure to mention changes in temperature, winds, dewpoint and pressure.

     

  7. Answer the following questions about drylines:
    • In what part of the country do you typically find drylines?
    • What two types of air masses are typically separated by drylines?
    • Which of the two air masses listed in the previous question is MORE DENSE?

     

  8. True or false: A stationary front is depicted on weather maps by alternating triangles and half circles on opposite sides.

     

  9. True or false: An air mass source region is an area of significant weather including strong winds.

     

  10. What is overrunning? What kinds of clouds are the result of overrunning?
