What weather change accompanies the passage of a cold front in the Northern Hemisphere?

AI Explanation
The correct answer is A) A line of cumulonimbus clouds. The passage of a cold front in the Northern Hemisphere is typically accompanied by the development of a line of cumulonimbus (thunderstorm) clouds. As the cold front moves through, the cooler air mass behind the front forces the warmer, moist air ahead of the front to rise rapidly, leading to the formation of these tall, towering clouds. The other options are incorrect because: B) steady precipitation does not necessarily accompany a cold front, C) the wind shift is from southwest to northwest, not northeast to southwest, and D) a dropping barometric pressure is a general indication of an approaching weather system, not specifically a cold front.
