If a weather bulletin shows the center of a low pressure system to be 100 miles due east of you, what winds can you expect in the Southern Hemisphere?

Correct Answer: Option B — South-southwesterly

In the Southern Hemisphere, winds circulate clockwise around a low-pressure center. With the low 100 miles due east, the observer is in the southwestern quadrant of the system. Applying Buys Ballot’s Law, the wind flow in this quadrant results in a south-southwesterly wind direction relative to the observer.
