What typically occurs when a cold front collides with a warm front?

• A. Heavy snowfall
• B. Thunderstorms and heavy rain
• C. Clear skies
• D. Gradual temperature increase

Answer: (B)

When a cold front collides with a warm front, the warm air, which is lighter, is forced to rise over the denser cold air. As this warm air ascends, it cools adiabatically, leading to the condensation of moisture in the air and the formation of clouds. This process often results in cumulonimbus clouds, which are associated with thunderstorms. The rise of the warm, moist air can also lead to heavy precipitation, often in the form of rain. Therefore, the presence of both a cold front and a warm front typically sets the stage for severe weather conditions, including thunderstorms and heavy rain. In contrast, heavy snowfall is more commonly associated with specific winter weather patterns rather than the dynamic of cold and warm fronts. Clear skies are unlikely to occur due to the chaotic weather changes brought about by the interaction between these fronts. Additionally, a gradual temperature increase does not typically characterize the behavior of cold and warm front interactions, as they often lead to more abrupt weather changes rather than a gradual shift.
