What kind of weather is associated with a stationary front?

Because a stationary front marks the boundary between two air masses, there are often differences in air temperature and wind on opposite sides of it. The weather is often cloudy along a stationary front, and rain or snow often falls, especially if the front is in an area of low atmospheric pressure.

What symbol shows stationary front?

A stationary front line is indicated by blue triangles on one side of the line alternating with red semi-circles on the opposite side of the line. The triangles point away from the colder air while the semi-circles point away from the warmest air.

What air mass wins during a stationary front?

Stationary Fronts Sometimes air masses exert similar strength forces on each other and no one wins. When one air mass is no stronger than the other, no movement occurs and you get a stationary front.

Which direction is the stationary front moving?

Winds on the cold air and warm air sides often flow nearly parallel to the stationary front, often in nearly opposite directions along either side of the front. A stationary front usually remains in the same area for hours to days, and may undulate as atmospheric short waves move eastward along the front.

What is a stalled front?

A stationary front is a non-moving (or stalled) boundary between two air masses, neither of which is strong enough to replace the other. They tend to remain essentially in the same area for extended periods of time, usually moving in waves.

What happens after a stationary front?

A stationary front can eventually dissipate, or, given a shift in upper-level winds or the relative strength of one or another of the air masses, might resume mobility as a cold or warm front.

What do the front symbols mean?

Cold Front: A cold front indicates a colder air mass is moving in the direction toward which the triangles are pointing. Stationary Front: A stationary front separates a warmer from a cooler air mass. A stationary front has a little or no movement thus the cold and warm front symbols are drawn in alternating fashion.

What kind of weather does a occluded front bring?

The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward. Such fronts can bring strong winds and heavy precipitation. Occluded fronts usually form around mature low pressure areas.

Why is it called stationary front?

A stationary front forms when a cold front or warm front stops moving. This happens when two masses of air are pushing against each other but neither is powerful enough to move the other. Winds blowing parallel to the front instead of perpendicular can help it stay in place. A stationary front may stay put for days.

What type of front occlusion usually moves the fastest?

Cold fronts often come with thunderstorms or other types of extreme weather. They usually move from west to east. Cold fronts move faster than warm fronts because cold air is denser, meaning there are more molecules of material in cold air than in warm air.

What weather does a occluded front bring?

An Occluded Front forms when a warm air mass gets caught between two cold air masses. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward. Such fronts can bring strong winds and heavy precipitation.

What is a warm front symbol?

The symbol that is used to identify a warm front on a weather map is a red line with half circles that point in the direction in which the warm front is moving. The line represents the leading edge of the warmer air mass.
