• Warm Front

• Low Pressure

• High Pressure

• Air Mass

A place where the air is pushing down with more force than the surrounding areas, usually resulting in clear, dry weather because the air is sinking and not carrying much moisture.

• High Pressure

• Occluded Front

• Air Mass

• Low Pressure

NGSS.MS-ESS2-5

An area where the air pressure is lower than the surrounding areas, often causing clouds and preciptation to form because the air rises in that spot.

When a cold air mass moves into a warmer air mass, forcing the warm air to quickly rise and condense. It brings heavy precipitation, thunderstorms, hail, lightning, wind gusts, and a sudden drop in temperature.

• Occluded Front

• Warm Front

• Cold Front

When a war air mass pushes into a cooler air mass, causing the warm air to slowly rise over the cold air, typrically resulting in a broad area of clouds and light precipitation, and a rise in temperature.

• Stationary Front

• Warm Front

• Cold Front

• High Pressure

When a cold air mass overtakes a warm air mass, trapping the warm air between two cooler air masses. It brings stong winds, clouds, and heavy precipitation.

• Cold Front

• Warm Front

• Air Pressure

When two air masses meet and neither can move the other. It brings many days of clouds and light precipitation.

• High Pressure

• Occluded Front

• Cold Front

• Stationary Front
