Consider the following statements regarding 'Front' : 1. The region where a front is moving experiences a slow change in weather. 2. Cold front is associated with thunderstorms. 3. Warm front is the boundary between an advancing warm air mass and a cold air mass, where the warm air dominates the cold air and rises above it. Which of the above statements is/are correct ?

Statement 1 is incorrect because the region where a front is passing experiences a rapid, not slow, change in weather conditions. Statement 2 is correct: cold fronts are associated with the rapid uplift of warm air, leading to thunderstorms and intense precipitation. Statement 3 is correct as a warm front is the boundary where an advancing warm air mass meets a cold air mass; the warm, less dense air glides up over the cold air, dominating and rising above it. Hence statements 2 and 3 are correct.
