  1. FRONTS

  2. FRONT Where air masses meet and do not mix.

  3. 4 Types of weather fronts: Cold Front Warm Front Stationary Front Occluded Front

  4. Cold Front When a fast moving cold air mass runs into a slow moving warm air mass and the denser cold air slides under the less dense warmer air.

  5. Cold Front • An animation:

  6. A cold front symbol—The direction that the teeth point indicate the direction the front is moving.

  7. Warm Front When a moving warm air mass collides with a slowly moving cold air mass and the less dense warm air moves over the cold air.

  8. Warm Front • An animation:

  9. Warm Front symbol—The directions that the bumps face is the direction the front is moving.

  10. Stationary Front When a cold air mass and warm air mass meet, but neither air mass has enough force to move the other air mass.

  11. Stationary Front Symbol

  12. Occluded Front When a warm air mass is caught between two cooler air masses and the denser cold air masses move underneath the less dense warm air mass and push it upward.

  13. Occluded front symbol – The directions that the bumps face is the direction the front is moving.

  14. Cold, Warm, Stationary, Occluded Animations

  15. Which types of fronts can you find on this map?
