What are the 4 types of fronts?
There are four basic types of fronts, and the weather associated with them varies.
- Cold Front. A cold front is the leading edge of a colder air mass. …
- Warm Front. Warm fronts tend to move slower than cold fronts and are the leading edge of warm air moving northward. …
- Stationary Front. …
- Occluded Front.

How do you draw a occluded front?
Symbolically, an occluded front is represented by a solid line with alternating triangles and circles pointing the direction the front is moving. On colored weather maps, an occluded front is drawn with a solid purple line.
How do you draw a stationary front?
Once this boundary resumes its forward motion, it once again becomes a warm front or cold front. A stationary front is represented by alternating blue and red lines with blue triangles pointing towards the warmer air and red semicircles pointing towards the colder air.
What is a stationary front symbol?
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 happens in a 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.
How are cold fronts different from stationary fronts?
Cold Front – a zone separating two air masses, of which the cooler, denser mass is advancing and replacing the warmer. Warm Front – a transition zone between a mass of warm air and the cold air it is replacing. Stationary Front – a front between warm and cold air masses that is moving very slowly or not at all.
What are stationary and occluded fronts?
Stationary Front – a front between warm and cold air masses that is moving very slowly or not at all. Occluded Front – a composite of two fronts, formed as a cold front overtakes a warm or quasi-stationary front.
What is a purple front?
The symbol for an occluded front is a purple line with alternating triangles and semi-circles (also purple) pointing in the direction the front is moving.
What weather is in a stationary front?
A wide variety of weather may occur along a stationary front. If one or both air masses are humid enough, cloudy skies and prolonged precipitation can occur, with mesocyclone systems. When the warmer air mass is very humid, heavy or extreme precipitation can occur.
What type of clouds form in a stationary front?
Warm, less dense, low pressure air mass moves towards a cold, dense, high pressure air mass. The air masses stay essentially in one place, or the air masses stay stationary. Stationary fronts often produce nimbostratus clouds. Nimbostratus clouds are rain clouds that are in layers.
What do stationary fronts bring?
On occasion, a stationary front can lead to extreme events. When a high percentage of moisture is present in the atmosphere, heavy & persistent rain can lead to flooding in the region along the front. Heavy winds called Derechos sometimes develop due to strong downdrafts along the border of a stationary front.
What kind of clouds do stationary fronts bring?
Warm, less dense, low pressure air mass moves towards a cold, dense, high pressure air mass. The air masses stay essentially in one place, or the air masses stay stationary. Stationary fronts often produce nimbostratus clouds. Nimbostratus clouds are rain clouds that are in layers.
What direction do stationary fronts move?
Winds along a stationary front are usually parallel to the front blowing in opposite directions on either side which is one reason why the front does not move. Stationary fronts essentially have no surface movement, or very slow movement of less than 5 mph at the surface.
What type of weather do stationary fronts 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 do stationary fronts bring?
A stationary front is also often accompanied by overcast and dreary weather with persistent light precipitation that can last for days. This condition usually depends on the amount of moisture present in the air. On occasion, a stationary front can lead to extreme events.
Is a stationary front warm or cold?
Stationary Front – a front between warm and cold air masses that is moving very slowly or not at all. Occluded Front – a composite of two fronts, formed as a cold front overtakes a warm or quasi-stationary front.
What does a orange door mean?
An orange front door says, “refreshing fun.” If you choose an orange door, you may be the life-of-the-party, gregarious, anything-but-shy type. An orange front door works well on modern or mid-century modern homes.
What does a black door mean?

What is a stationary front and what weather does it bring?
Description. A stationary front is a weather front or transition zone between two air masses (cold and warm), when neither air mass is advancing into the other at a speed exceeding 5 knots at the ground surface.
What type of clouds form in stationary fronts?
Warm, less dense, low pressure air mass moves towards a cold, dense, high pressure air mass. The air masses stay essentially in one place, or the air masses stay stationary. Stationary fronts often produce nimbostratus clouds. Nimbostratus clouds are rain clouds that are in layers.
What kind of clouds form in a stationary front?
Clouds associated with stationary fronts are usually stratiform (stratus nimbostratus altostratus cirrostratus).
What weather occurs in 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 happens at stationary fronts?
Description. A stationary front is a weather front or transition zone between two air masses (cold and warm), when neither air mass is advancing into the other at a speed exceeding 5 knots at the ground surface.
How does a stationary front work?

Are stationary fronts warm or cold?
Stationary Front – a front between warm and cold air masses that is moving very slowly or not at all. Occluded Front – a composite of two fronts, formed as a cold front overtakes a warm or quasi-stationary front.
Do stationary fronts cause thunderstorms?
A thunderstorm is a storm that produces thunder and rain, on average lasting about 30 minutes and averaging about 15 miles in diameter. There are four types of weather fronts that cause thunderstorms: cold front, warm front, stationary front and occluded front.

Sometimes a stationary fronts could produce severe weather. There could be a band of thunderstorms or heavy rain may be pushed down from the front, which could lead to flooding.
