Isobar Data
Add the data to the isobar map and use that data to answer the questions.

1. Label high-pressure areas with the letter H.

2. Label low-pressure areas with the letter L.

3. Over which area(s) would you expect to see rain or snow?

4. Over which area(s) would you expect to see clear skies?

In the northern hemisphere, the wind blows clockwise around centers of high pressure. The wind blows counterclockwise around lows. It is the opposite in the southern hemisphere.

5. Draw arrows around the H on the map to show the wind direction.

6. Draw arrows around the L on the map to show the wind direction.

7. Imagine that you live in Maine. Currently there is a high-pressure area over Maine. If a low-pressure area moves in, how will the direction of the wind change?

8. Imagine that you live in Colorado. Currently there is a low-pressure area over Colorado. If a high-pressure area moves in, how will the direction of the wind change?

9. According to the map, where would the strongest winds be expected? (Refer to the lesson if needed.)
