| high pressure system | a large body of sinking air moving clockwise that brings clear, fair weather |
| low pressure system | a large body of rising air moving counterclockwise that brings clouds and precipitation |
| arctic air mass | forms over Siberia and the Arctic and contains bitterly cold, dry air. |
| continental polar air mass | fast moving dry and cold air mass that brings cold temps in the winter and cool weather in summer |
| maritime polar air mass | wet and cold air mass that brings cloudy, rainy weather |
| continental tropical air mass | hot and dry air mass that bring clear skies and high temps. Usually form in the summer |

| cold front | when a dense fast moving cold air mass pushes underneath a less dense warm air mass causing clouds to form which bring heavy rain and thunderstorms |
| warm front | when a less dense slow moving air mass glides over a cold air mass causing wide blankets of clouds to form that bring steady rainfall. |
| stationary front | when a cold air mass and a warm air mass meet and are equally matched. |
| occluded front | a cold air mass is already in place and a warm air mass slowly tries to glide over top but a bigger much faster moving cold air mass pushes underneath sending both of the others up in the atmosphere |
