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! |
