Question 1263Navigation General

The correct answer is D) cold front. Cumulonimbus clouds are large, vertically-developed clouds that often produce thunderstorms. These types of clouds are most commonly associated with the passage of a cold front, where the introduction of colder, denser air causes the warm, moist air ahead of the front to rapidly rise, resulting in the formation of towering cumulonimbus clouds. The other answer choices are incorrect because warm fronts, occluded fronts, and high pressure systems are not as closely linked to the development of cumulonimbus clouds as cold fronts. Warm fronts typically produce more stratiform, layered cloud types, occluded fronts are a mix of warm and cold fronts, and high pressure systems are generally associated with more stable, fair weather conditions.
