Investigation 1B
1. Based on Figure 1, which of the following best describes the surface wind circulation around
the center of a low pressure system? counterclockwise and inward spiral
2. Based on Figure 2, which of the following best describes the surface wind circulation around
the center of a high-pressure system? clockwise and outward spiral
3. For the Low, the palm of your hand rises during the rotating motion.
4. For the High, the palm of your hand falls during the rotating motion.
5. Vertical air motion in the Low is therefore downward.
6. In the case of the High, vertical air motion is upward.

7. Considering the complete air motions of the low-pressure system, air flows downward,
inward and counterclockwise.

9. The wind direction at San Antonio, in south-central Texas, at map time was generally from
the South.

10. Given the direction the wind at San Antonio was from, it will be reported as
aC s
a north wind.

11. Wind directions at these stations suggest that, as seen from above, the air spiraled generally
counterclockwise around this Northern Hemisphere low-pressure center.

12. The winds at stations near the low-pressure center indicated that the air also was directed
generally inward toward the low-pressure center.
13. This wind flow pattern about the Low is therefore consistent with the hand-twist model of a

Low.

15. The air also spiraled generally outward from the high-pressure center.
16. This wind flow pattern about the High is consistent with the hand-twist model of a High.
17. The isobar pattern on that map did not generally depict the positions of the L and the H
found on this Figure 3 map.
