A
passage of a warm front
B
passage of a cold front
C
stationary high pressure systems
D
winds shifting counterclockwise in the Northern Hemisphere
AI Explanation
The correct answer is B) passage of a cold front. Brief, violent showers accompanied by thunder and lightning are typically associated with the passage of a cold front. As a cold front moves through an area, the colder air behind the front forces the warmer, more humid air ahead of the front to rise rapidly, leading to the development of thunderstorms and heavy downpours. This is in contrast to the other options, which are not as directly linked to this type of weather phenomenon.
