In terms of movement, how does an occluded front behave?

An occluded front forms when a cold front overtakes a warm front, which is characteristic of transitional weather systems. In this scenario, the cold front's faster movement allows it to catch up to the warm front. As a result, the warm air mass gets lifted off the ground, creating the occluded front. This process often occurs in mid-latitude cyclones where complex interactions between different air masses are commonplace.

The behavior of an occluded front is crucial to understanding weather patterns, as it often leads to the development of clouds and precipitation associated with the lifting of warm air. This lifting can produce varying weather conditions that are significant for forecasting.

The other choices do not accurately describe the dynamics of occluded fronts. The occluded front does not stay stationary, nor does it only develop during winter storms. It is also not accurate to state that the cold front moves away from the warm front, as this would suggest a divergence rather than the convergence and interaction that defines an occluded front.
