🔍 Key Concepts

• Counterclockwise circulation around a low-pressure system in the Northern Hemisphere • Using Buys Ballot's Law (face the wind, low pressure is on your left in the Northern Hemisphere) • Typical pressure change (barometer trend) and wind direction as a storm passes

💭 Think About

• Sketch (mentally or on paper) a low-pressure center moving east, then mark the point where you are south of the center and draw the counterclockwise wind arrows around it. • From that sketch, determine what general wind direction a vessel south of the low would feel. • Think about whether a vessel close to the center of a strong storm is more likely to experience clear, calm conditions or stronger winds and active weather.

✅ Before You Answer

• Verify which way the wind flows around a low in the Northern Hemisphere (clockwise or counterclockwise). • Check whether being south of the low puts you in the warm, moist sector or the cold, dry sector of the storm system. • Consider if a storm center nearby would normally cause a falling or rising barometer at your location.
