9. Cold Front
Boundary formed where a cold air mass overtakes and lifts a warm air mass

10. Squall Line Long line of heavy thunderstorms
May occur just ahead of a fast moving cold front

12. Warm Front
Boundary formed where a warm air mass overtakes and rises over a cold air mass

13. Stationary Front Boundary between two air masses
Neither one is displaced
Weather

14. Occluded Front
Formed where a fast moving cold air mass overtakes and lifts a warm air mass, completely cutting it off from the ground

15. Polar Front
Boundary at which cold polar air meets the warmer air of the middle latitudes

16. High-pressure Systems
Spin outward and clockwise

17. Low-pressure Systems
Spin inward and counter-clockwise

18. Wave Cyclone
Large storm that develops along cold or stationary fronts, with winds that spiral in toward a central region of low air pressure
