Question 1017Navigation General

The correct answer is C) tropical waves. Tropical waves are low pressure disturbances that originate along the intertropical convergence zone, a region near the equator where the northeast and southeast trade winds converge. These waves travel westward along the convergence zone and can sometimes develop into more severe weather systems like tropical storms or hurricanes. The other answer choices are incorrect: A) permanent waves refer to ocean waves, not atmospheric disturbances; B) tropical storms are more severe weather systems that can develop from tropical waves; and D) tidal waves are large ocean waves caused by events like earthquakes, not low pressure systems.
