  1. weather fronts caused by colliding air masses.
  2. Ah, warm front is the leading edge of a mouse
  3. of moving warm air.
  4. Warm fronts usually moves slowly and are often marked by
  5. rain and cloudy skies.
  6. Cold fronts form when quickly moving cold air Masses collide
  7. with more slowly moving warm air masses.
  8. Because cold air is denser, it sinks beneath warm air,
  9. and since cold fronts move quickly, they are also associated
  10. with quickly changing weather conditions, which may include thunderstorms.
  11. Cold fronts, air usually associated with lower air pressure.
  12. Next, an occluded front occurs when a cold air front
  13. takes over a warm air front front.
  14. This could be like an air mass sandwich in which
  15. the warm air mass becomes stuck between two cold air
  16. masses. The denser cold air masses lodged themselves around the
  17. warm air mass, pushing the warm air mass farther away
  18. from the earth's surface.
  19. The cold air masses air, then left to mix near
  20. the ground, cooling the temperatures we experience.
  21. Usually, these fronts are associated with the drying of the
  22. air. Lastly, a stationary front refers to the meeting of
  23. two air masses that do not overtake each other.
  24. With this front a cold air mass and a warm
  25. air mass, maybe next to each other, but they move
  26. along at the same pace, leading to extended rain, snow,
  27. fog or clouds at the boundary.
  28. Please take a minute to look at the diagrams to
  29. the right so that you can see what happens during
  30. the different types of fronts.
