A stationary front is depicted by an alternating red and blue line with a triangle on the blue portion and half-moon on the opposite side of the red portion of the line . A cold front (or warm front) that stops moving becomes a stationary front.
What is the color scheme for a stationary front?
When you look at the weather map, a stationary front is represented as red semi-circles and blue triangles like on the map below. The blue triangles will point in one direction representative of the cold air and the warm front represented by the red semi-circles represents the warmer air.
What is a symbol for a warm front?
A red line with half-circles on one side signifies a warm front. A warm front shows the leading edge of warmer air trying to replace a colder air mass. The half circles always point in the direction that the front (and the warmer air) is moving.
What color is a occluded front?
An occluded front is represented on a weather map by a purple line with alternating triangles and semicircles.
What color is a warm front?
A warm front is the transition area where a mass of warm air moves to replace a mass of cold air. On a weather map, a warm front is usually drawn using a solid red line with half circles pointing in the direction of the cold air that will be replaced. Warm fronts usually move from southwest to northeast.
What is the weather map symbol for a stationary front?
A stationary front is depicted by an alternating red and blue line with a triangle on the blue portion and half-moon on the opposite side of the red portion of the line . A cold front (or warm front) that stops moving becomes a stationary front.
What weather comes 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 does a stationary front bring?
A stationary front may bring days of rain, drizzle, and fog . Winds usually blow parallel to the front, but in opposite directions. After several days, the front will likely break apart. When a cold air mass takes the place of a warm air mass, there is a cold front.
What weather does an 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 another name for occluded front?
noun Meteorology. a composite front formed when a cold front overtakes a warm front and forces it aloft. Also called occlusion .
Are occluded fronts stationary?
Small isolated occluded fronts often remain for a time after a low pressure system has decayed and these create cloudy conditions with patchy rain or showers. However, the clouds and precipitation are not really where the projection on the Earth’s surface of the occluded front is, but with the trowal position.
What are characteristics of a warm front?
Warm fronts are boundaries of slow-moving air masses that replace masses of colder air ahead of them . Warm fronts typically travel between 10 and 25 miles per hour and contain warm, humid air. As the warm air is lifted, the temperature drops and condensation occurs, forming clouds.
What are the first signs of an approaching warm front?
The first signs of an approaching warm front are the appearance of high, thin, wispy cirrus clouds . As the front nears, the clouds will become lower in the sky and be thicker, since there will be more air at lower elevations from which to condense clouds.
What does a warm front look like?
Symbolically, a warm front is represented by a solid line with semicircles pointing towards the colder air and in the direction of movement . On colored weather maps, a warm front is drawn with a solid red line. There is typically a noticeable temperature change from one side of the warm front to the other.
What type of clouds form in a stationary front?
Clouds associated with stationary fronts are usually stratiform (stratus, nimbostratus, altostratus, cirrostratus) .
Why is a weather front called a front?
front, in meteorology, interface or transition zone between two air masses of different density and temperature ; the sporadic flareups of weather along this zone, with occasional thunderstorms and electrical activity, was, to the Norwegian meteorologists who gave it its name during World War I, analogous to the ...
