Question 1264Navigation General

The correct answer is B) stationary front. When a cold air mass and a warm air mass meet, and there is no horizontal motion of either air mass, it is called a stationary front. In this scenario, the boundary between the two air masses remains stationary, as neither the cold air mass nor the warm air mass is moving. This is in contrast to a cold front (A), where the cold air mass is advancing, or a warm front (C), where the warm air mass is advancing. An occluded front (D) occurs when a cold front overtakes a warm front, which is also not the case in the given scenario.
