Creating and Analyzing Weather
MapsObjective –
You will construct field maps and learn to identify patterns that can be used to predict
weather.
Procedure –
1.On map A use a pencil to draw isotherms at a 10-degree interval (30, 40, 50, 60, and 70 degrees)
2.On map A label the isotherms

Procedure – 3. On map B use a pencil to
draw isobars between points of equal atmospheric pressure. (040, 080, 120, 160, and 200)
4. On map B label the isobars
5. On map B label the high and low pressure areas
Procedure – 6. On map C use a pencil to
extend the tail of the station model to show the direction each station model is blowing
7. On map C use a pen to draw larger arrows to show the general pattern of air flow
Procedure – 8. On map D the symbol “R”
inside the station model indicates rain. Draw a line around this area then lightly shade it using a pencil.
9. On map D draw the symbols for a cold and warm front along the area of precipitation
