Objectives #26 (December
By the end of today's class, you should be able to do the following:
w Review: Explain why as warm, moist air rises it may form clouds that yield precipitation.
w Review: Explain why precipitation is associated with warm fronts and with cold fronts.
w New today: Let's add two new types of fronts: stationary fronts and occluded fronts.
Here are a few websites explaining fronts: From the University of Illinois From the Oklahoma Climatological Survey From Eduplace.com
w Review: Complete the data collection and analysis of the "Weather Tracking Day 1" worksheet, and compare your CONCLUSIONS with the rest of the class.
w Review: Move on to "Weather Tracking Day 2", using the map linked here., and compare your CONCLUSIONS with the rest of the class.
w Explain the meaning of air pressure / barometric pressure.
w Tell what makes the wind blow, and how winds are named (e.g. "west wind", "north wind", and so on).
w Describe the rotation of winds about a high pressure center and a low pressure center.
w Tell what kind of weather generally accompanies highs and lows.
w Using a slip of paper with a circle to represent a HIGH or a LOW, describe how the winds change in Chicago under the following situations:
|A HIGH approaches
Chicago, passes directly over it, and then moves on.
A LOW approaches Chicago, passes directly over it, and then moves on.
|A HIGH passes to the
north of Chicago.
A LOW passes to the north of Chicago.
| A HIGH
passes to the south of Chicago.
A LOW passes to the south of Chicago.
Putting together all the data
trends we have observed, particularly regarding air masses, fronts, highs,
lows, and winds, forecast the weather.
w Practice forecasting using today's weather map from the Chicago Tribune (it's a big 2 MB file--patience, please!)
Coming up: What are the global causes of weather? (start with deciphering the coriolis force)
