A front caused by a cold air front and a warm air front battling and staying in place over an area for a while is called?

occluded front

Explanation:

Sometimes a cold front follows right behind a warm front. A warm air mass pushes into a colder air mass (the warm front), and then another cold air mass pushes into the warm air mass (the cold front). Because cold fronts move faster, the cold front is likely to overtake the warm front. This is known as an occluded front.
