The type of front that is represented by this cross section is the occluded
<h3>What kind of front is an occluded front?</h3>
A warm air mass pushes on a cooler air mass (the warm front) and then another cold air mass pushes on the warmer air mass (the cold front). As cold fronts move faster, the cold front is likely to overtake the warm front. This is known as an occluded front.
With this information, we can conclude that the type of front that is represented by this cross section is the occluded.
