Q. Consider the following statements:
Which of the above statements is/are correct?
When two different air masses meet, the boundary zone between them is called a front.
Statement 1 is incorrect: A warm front moves much more slowly than a cold front, therefore it often happens that the cold front catches up with the warm front, resulting in an occluded front. A cold front moves up to twice as quickly as warm fronts.
Statement 2 is correct: Both warm front and cold are invariably associated with cloudiness and precipitation because of the ascent of warm air.
Statement 3 is incorrect: In a cold front set-up, the boundary between the cold and warm air masses is relatively steep, typically causing the warm air in front of it to rise rapidly. This rising air creates energetic, cumulonimbus clouds leading to showers and thunderstorms.
