Your weather chart indicates that you will cross the cold front of a low-pressure system in about 24 hours. Which statement is TRUE?

🔍 Key Concepts

• Cold front vs. warm front cloud patterns • Typical weather hazards near a cold front (wind, pressure, squalls) • Meaning of navigable semicircle in relation to low-pressure systems

💭 Think About

• Think about what kind of front usually produces a long sequence of layered clouds (cirrus, altostratus, nimbostratus) over many hours or days. • Consider what happens to wind speed, wind direction, and thunderstorm activity as a cold front actually passes over your position. • Ask yourself in what specific situation mariners talk about the ‘navigable semicircle’ and whether that applies to an ordinary cold front on a mid-latitude chart.

✅ Before You Answer

• Verify which type of front is associated with towering cumulonimbus, squall lines, and sudden wind shifts. • Confirm whether the navigable semicircle concept applies to any low-pressure system or specifically to tropical cyclones/hurricanes. • Check if it is realistic to expect clear, steady weather and pressure right up until a cold front passes.
