7. Air mass
Definition: body of air with same temperature, humidity, and pressure
Example: continental, tropical, maritime, polar
Picture/Visual:

8. Source Regions Definition: The area over which air masses form.

Picture/Visual:

9. Continental Maritime Definition: Air masses that form over land.
form over water.

10. Polar Tropical Definition: Air that forms in polar, cold regions.
in tropical, hot regions.

11. High pressure
Definition: whirling mass of cool, dry air that generally brings fair weather and light winds
Example: sunny skies or High=Happy weather
Picture/Visual:

12. Low pressure
Definition: a whirling mass of warm, moist air that generally brings stormy weather with strong winds
Example: Low pressure=loser weather
Picture/Visual:

13. Front Definition: the front of an air mass. Example: cold front
Picture/Visual:

14. Cold front
Definition: boundary of an advancing mass of cold air, trailing edge of a low-pressure system
Example: cold air mass is replacing a warm air mass-temps decrease
Picture/Visual:

15. Warm front
Definition: advancing mass of warm air, in particular the leading edge of a high-pressure system
Example: moving mass of warm air- often means rain is coming
Picture/Visual:

16. Stationary Front
Definition: Boundary between a warm air mass and a cold air mass that hit one another.
Example: often means rain is coming
Picture/Visual:

17. Occluded Front
Definition: Occurs when a warm front is located in the middle of two cold air masses.
Example: often means rain is coming
