What defines an occluded front?

Occluded fronts form when a faster-moving cold front overtakes a slower warm front, lifting the warm air off the surface. As the cold air catches up, it wedges under the warm air, forcing that warm air aloft and creating a merged front boundary aloft. This lifting often leads to widespread precipitation along the occlusion as the warm air rises and cools. The other scenarios describe different frontal setups: a warm front overtaking a cold front is not the usual occlusion, a stationary front has no movement, and a retreating warm front indicates the warm air is shrinking rather than being lifted by an approaching cold air mass.
