Final answer:
Occluded and stationary fronts are formed by the interaction of different air masses, leading to specific weather conditions.
Explanation:
An occluded front occurs when a warm air mass becomes trapped between two cold air masses, leading to cloudy weather and precipitation.
A stationary front happens when two contrasting air masses meet but neither can overtake the other, resulting in mild but prolonged precipitation.
Cold air masses from the poles meeting warm air masses from the tropics create different types of fronts including cold, warm, occluded, and stationary fronts, each with distinct characteristics and weather patterns.
