What are the weather front symbols?
Cold fronts are marked on weather maps with the symbol of a blue line of triangles/spikes (pips) pointing in the direction of travel, and are placed at the leading edge of the cooler air mass..
How do you identify an occluded 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. Sometimes a cold front will “catch up” to a warm front and overtake both it and the cooler air out ahead of it. If this happens, an occluded front is born.

How do fronts and pressure systems affect weather?
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. … Warm fronts are often associated with high-pressure systems, where warm air is pressed close to the ground. High-pressure systems usually indicate calm, clear weather.
What type of front causes severe weather?
Cold fronts occur when warm air is pushed up into the atmosphere by colder air at the ground. These fronts tend to move faster than the other types of fronts and are associated with the most violent types of weather such as severe and super cell thunderstorms, although any type of front can produce these same storms.
What type of weather occurs in a occluded front?
Occluded Front Forms when a warm air mass gets caught between two cold air masses. The warm air mass rises as the cool air masses push and meet in the middle. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward. Can bring strong winds and heavy precipitation.
What are 4 types of weather?
The weather also describes how air moves, and anything that the air may carry, such as clouds, rain, or snow. The five main types of weather are sunny, rainy, snowy, cloudy, partly cloudy, and windy.
What is a severe front?
For severe weather to be associated with cold fronts, look for the following: high dewpoints ahead of the front (60 F or greater), strong upper level winds (300 mb wind greater than 120 knots), front movement between 10 and 20 mph, and convergence along the front.
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.
What causes weather fronts?
This happens when two masses of air are pushing against each other, but neither is powerful enough to move the other. … 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.
What are the four types of fronts and describe the type of weather each brings?
Fronts are boundaries between air masses of different temperatures. … The type of front depends on both the direction in which the air mass is moving and the characteristics of the air mass. There are four types of fronts that will be described below: cold front, warm front, stationary front, and occluded front.
