Question

***Kinda need this in under 24hours**

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.)

Answer 1

Answers to the questions:

1 and 2. (Image 1.) All the high or low pressure areas are marked. Standard atmospheric pressure is 1,013.25 millibars. Everything above is high pressure and everything below is low pressure.

3. Low pressure areas. These areas are basically storms. As hurricanes and blizzard are classified as storms, one expects snow or rain in areas with low atmospheric pressure.

4. High pressure areas. These areas are associated with light winds and the phenomenon known as subscidence. Through adiabatic or compressional heating the air mass is ”dried out”. This is known as subscidence.

5 and 6. (Image 2.) Northern Hemisphere: high pressure – clockwise direction, low pressure – counterclockwise

7. As winds move in an anticlockwise manner around a low-pressure area, currently, the wind will blow from a southwestern to northeastern direction. However, as soon as the low-pressure area moves in, the wind will blow from a southeastern to a northwestern direction.

8. As winds move in a clockwise manner around a low-pressure area, currently, the wind will blow from a southeastern to a northwestern direction. However, as soon as the high-pressure area moves in, the wind will blow from a southwestern to northeastern direction.

9. (Image 3). Strong winds are indicated by closely packed isobars as they indicate a steep horizontal pressure gradient.
