Occluded Front

  • Cut off, as the warm air mass at an occluded front is cut from the ground by cooler air beneath it
12.

Stationary Front

  • a boundary between air masses that don't move possibly causing rain for several days

Warm Front

  • the leading edge of a warm air mass overtaking a cooler, slower air mass
