DAILY OBJECTIVES
By the end of today's class, you should be able to do the following:

WEATHER

w
  Review:  Make a sketch of a warm front and use it to explain why precipitation is associated with these fronts. 

w   Review:  Make a sketch of a cold front and use it to explain why precipitation is associated with these fronts. 

w   Recall from last class:  The data you collected showed that in general, cold fronts move south and east, while warm fronts move north and east


w
  Using the attached data collection form, analyze the Tribune weather maps we assembled over the past 3-4 weeks.  Today we will focus on high and low pressure systems, fronts, winds, and precipitation.

Barometric Pressure


w   Describe the characteristics and movement of air in a high pressure zone and a low pressure zone.

w   Describe the direction of winds related to a high pressure zone; then do the same for a low pressure zone.

w   Explain why weather systems commonly move from west to east in the United States.

w   Given that highs and lows generally move west to east, demonstrate that you can describe and explain the changes in weather for Chicago when a...

...HIGH pressure system passes...

...LOW pressure system passes...

..from west to east, to the north of Chicago.   ...from west to east, to the north of Chicago.  
...from west to east, to the south of Chicago.   ...from west to east, to the south of Chicago.  
...from west to east, directly over Chicago.   ...from west to east, directly over Chicago.  

HINT:  Use this map and a piece of tracing paper.  Trace the high and the low, and draw arrows on each to show wind direction.  Then slide the tracing paper across the map from west to east, examining how barometric pressure and wind direction change for a given location as the system moves.

Forecasting

w   Here are weather maps for December 7, December 8, and December 9.  Use them to make predictions of temperature and precipitation for specific cities in the US, using what you know about high and low pressure zones, fronts, wind directions, temperature of air masses, and precipitation.

COURSE EVALUATIONS

w   We will do the official departmental Course Evaluations at the end of class today!
