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
