General Navigation USCG Question #1095 (Set 34)

You are in the Northern Hemisphere and a tropical wave is located 200 miles due west of your position. Where will the wave be located 24 hours later?

Official USCG Answer & Rule Citation

Correct Answer: Option A — Farther away to the west

According to Bowditch, tropical waves in the Northern Hemisphere typically move westward at 10 to 20 knots within the trade wind belt. A wave located 200 miles due west will be overtaken and moved farther away to the west as the dominant general circulation progresses.
