Low Pressure =
•cloudy weather and precipitation
•Centers of all storms have areas of
low pressure
Map Symbol Flashcards
High Pressure =
•sunny to partly cloudy weather
•High pressure areas cause air to sink which
prevents the formation of clouds and
precipitation.

Warm Front =
•Warm air approaches cold air and rides over
the cold air
•The warm air has a lot of water vapor that
condenses due to the cold air underneath and
causes clouds and precipitation.

Cold Front =
•Cold air approaches warm air and sinks under the
warm air
•The cold air is more dense and sinks under the
lighter, warmer air. Cold fronts bring less humid air,
which makes for slightly “cooler” temperatures.

Occluded Front =
•Cold occlusion: air behind the front is colder than the air ahead
of the front. The coldest air undercuts the cool air ahead of the
front and the occluded front acts like a cold front.
•Warm occlusion: the air behind the front is warmer than the air
ahead of the front. The warmer air is lighter than the coldest air
ahead of the front. The warmer air rises up and over the coldest
air at the surface and this occluded front acts like a warm front.

Stationary Front =
•The boundary between cold air and warm air when neither
type of air is “winning the battle.”
•Brings several days of cloudy, wet weather that can last a week
or more.

Troughs =
•An elongated area of low atmospheric pressure
•Areas to the east of a trough usually have precipitation
•Areas to the west of a trough typically have colder, drier air

•Diagonal lines on a weather map indicates areas of rain.
