Creating and Analyzing
Weather Maps
Objective –
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
40
40
40
40
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
