Question 844Navigation General

The correct answer is D) cloud walls. The dense black cumulonimbus clouds surrounding the eye of a hurricane are called cloud walls. These towering cloud formations are a distinctive feature of hurricanes and other intense tropical cyclones. The cloud walls form a circular barrier around the calm, clear eye of the storm, where the lowest surface pressures and strongest winds are found. The other answer choices are incorrect because: A) Funnel clouds are not associated with hurricanes, but rather with tornadoes. B) Spiral rainbands are separate bands of rain that spiral outward from the hurricane's eye, not the dense clouds immediately surrounding it. C) Cyclonic spirals refer to the overall spiral structure of the hurricane, not the specific cloud formations.
