General Navigation USCG Question #763 (Set 24)

When drawing a weather map and an isobar crosses a front, the isobar is drawn __________.

Official USCG Answer & Rule Citation

Correct Answer: Option C — kinked and pointing away from the low

Meteorological standards dictate that isobars crossing a front must change direction abruptly. Because pressure is higher on the cold side of a front, the isobars must kink toward the area of lower pressure, which means they point away from the low-pressure center when crossing the frontal boundary.
