🔍 Key Concepts

• Wind shifts with frontal passage in the Northern Hemisphere • Relationship between pressure systems (high/low) and wind direction changes • Typical weather changes with a cold front vs. warm front vs. stationary front

💭 Think About

• Think about what usually happens to wind direction and speed right AFTER a strong front moves through your area in the Northern Hemisphere. • Ask yourself: when winds suddenly swing around to the west or northwest and pick up, is the main weather system still coming toward you, directly over you, or has it just gone by? • Consider which front type is most often associated with abrupt changes in wind, temperature, and pressure rather than slow, gradual changes.

✅ Before You Answer

• Verify which system or front is known for abrupt, strong wind shifts instead of gradual veers or backing. • Check which type of front is commonly followed by cooler, drier air and clearing conditions, and what wind direction that brings in the Northern Hemisphere. • Eliminate any option that would more likely cause light, variable, or slowly changing winds rather than a sharp veer and increase in speed.
