Warm Front.

Stationary Front.

Occluded Front..

What are the symbols for weather fronts?

Stationary fronts appear on weather maps as alternating red and blue lines, with blue triangles pointing towards the side of the front occupied by warmer air, and red semi-circles pointing towards the cold air side.

What are fronts associated with?

Powered by A front is a weather system that is the boundary separating two different types of air. One type of air is usually denser than the other, with different temperatures and different levels of humidity. This clashing of air types causes weather: rain, snow, cold days, hot days, and windy days.

How do you read weather front symbols?

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. A warm front can initially bring some rain, followed by clear skies and warm temperatures.

Why is a weather front called a front?

When two air masses meet together, the boundary between the two is called a weather front. At a front, the two air masses have different densities, based on temperature, and do not easily mix. One air mass is lifted above the other, creating a low pressure zone.

What does a Purple weather front mean?

Occluded frontsOccluded Front The cold air mass is moving faster than the cool air mass. … Occluded fronts point to a decrease in intensity of the parent weather system and are indicated by a purple line with alternating triangles and half-moons on the side of its motion.

What is a cold occluded front?

More about occluded fronts A cold occlusion occurs when the air behind the occluded front is colder than the air ahead of it. The cold occlusion acts in a similar way to a cold front. The colder air behind the front undercuts and pushes up the air ahead of it. The other type of occluded front is the warm occlusion.

What do cold fronts bring?

Cold fronts usually bring cooler weather, clearing skies, and a sharp change in wind direction.

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 is the symbol for an occluded front?

Occluded fronts usually form with mature low pressure areas. They act like both warm and cold fronts. 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 are the four types of fronts and their symbols?

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.

Is a cold front?

A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. … The air behind a cold front is noticeably colder and drier than the air ahead of it. When a cold front passes through, temperatures can drop more than 15 degrees within the first hour.
