Question 785Navigation General

The correct answer is D) Low pressure. Tropical waves are associated with low-pressure systems that travel westward across the tropical regions. These low-pressure systems are characterized by a relative decrease in atmospheric pressure compared to the surrounding areas, which can lead to the development of clouds, thunderstorms, and other weather phenomena in the tropics. The other answer choices are incorrect because: A) High pressure systems generally do not travel in tropical waves, which are characterized by low pressure; B) Subsurface pressure is not directly related to the movement of tropical waves; and C) Terrastatic pressure is not a recognized meteorological term, and it does not accurately describe the pressure systems associated with tropical waves.
