What are the 3 fronts?
There are four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts.
What three air masses are involved in an occluded front?
An 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.
What type of air mass is in front of a cold front?
colder air Air mass boundaries Where air masses converge, they form boundaries called "fronts". 3-D view of a cold front. Fronts are identified by change of temperature based upon their motion. With a cold front, a colder air mass is replacing a warmer air mass.
What are 3 factors that often change at a front?
Fronts
- Sharp temperature changes over a relatively short distance.
- Change in moisture content.
- Rapid shifts in wind direction.
- Pressure changes.
- Clouds and precipitation patterns.
What were the 3 major fronts of WWI?
The western front was a long line of trenches that ran from the coast of Belgium to Switzerland. A lot of the fighting along this front took place in France and Belgium. The eastern front was between Germany, Austria-Hungary, and Bulgaria on one side and Russia and Romania on the other. How did it start?
How many air fronts meet in an occluded front?
three air masses Essentially, an occluded front forms as three air masses meet.
What is an occluded weather front?
Occluded fronts An occluded front is symbolised on a weather map as a line with both semicircles and triangles. They are often coloured purple. These are slightly more complex than cold or warm fronts. The word occluded means 'hidden' and an occlusion occurs when the cold front 'catches up' with the warm front.
What are continental air masses?
continental air mass, vast body of air that forms over the interior of a continent, excluding mountainous areas.
What is cold front and warm front?
A cold front extends to the south of the low pressure center, with a warm front to the east. Warm air is located ahead of the cold front and behind the warm front (the so-called "warm sector"), while cool air exists ahead of the warm front and cold air is present behind the cold front.
What were the Eastern and Western Fronts?
It stretched from the Baltic Sea in the north to the Black Sea in the south, involved most of Eastern Europe, and stretched deep into Central Europe as well. The term contrasts with "Western Front", which was being fought in Belgium and France.
What is the eastern front in ww1?
Eastern Front, major theatre of combat during World War I that included operations on the main Russian front as well as campaigns in Romania. The principal belligerents were Russia and Romania (of the Allied and Associated Powers) versus the Central Powers countries of Germany, Austria-Hungary, and Bulgaria.
What is cold front in geography?
A cold front develops when cold air meets an area of warm air. The warm air has a low density so it rises up above the cold air. Large storm clouds develop here as the temperature lowers and the water in the clouds starts to condense and forms rain. Cold Front.
What is cold front occlusion?
More about occluded fronts One is called a cold occlusion. 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.
What is cold front weather?
A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. Cold fronts generally move from northwest to southeast. The air behind a cold front is noticeably colder and drier than the air ahead of it.
What is the cold front?
A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. Cold fronts generally move from northwest to southeast. The air behind a cold front is noticeably colder and drier than the air ahead of it.
What is air mass front?
Fronts. Resources. An air mass is a body of air with a relatively constant temperature and moisture content over a significant altitude. Air masses typically cover hundreds, thousands, or millions of square kilometers. A front is the boundary at which two air masses of different temperature and moisture content meet.
What weather comes with 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.

What was the southern front?
Southern Front is a geographical area where armies are engaged in conflict, and may refer to: Southern Front (Soviet Union), one of the Soviet fronts in the World War II. Southern Front (RSFSR), a front of the Red Army during the Russian Civil War (1918-1920).
What was the Western Front during ww1?
The Western Front, a 400-plus mile stretch of land weaving through France and Belgium from the Swiss border to the North Sea, was the decisive front during the First World War. Whichever side won there – either the Central Powers or the Entente – would be able to claim victory for their respective alliance.
What is warm front in geography?
Warm fronts usually show up on the tail end of precipitation and fog. As they overtake cold air masses, warm fronts move slowly, usually from north to south. Because warm fronts aren't as dense or powerful as cold fronts, they bring more moderate and long-lasting weather patterns.
What happens during warm type occluded front?
A warm occlusion occurs when the cold air behind the occluded front is warmer than the air ahead of it. The warm occlusion acts in a similar way to a warm front. The cold air behind the front is less dense than the even colder air ahead of it, and so it passes over the top of the colder air.
What are the two types of occluded fronts?
Occluded fronts usually form around mature low pressure areas. There are two types of front occlusions, warm and cold, depending on the temperature contrast: In a cold occlusion, the cold air mass that overtakes the warm air mass ahead is colder than the cool air at the very front and plows under both air masses.
What do warm fronts cause?
Characteristics
| Weather phenomenon | While the front is passing |
|---|---|
| Temperature | Warming suddenly |
| Atmospheric pressure | Leveling off |
| Winds | Variable |
| Precipitation | Persistent rain, usually moderate with some lighter periods and some heavier bursts. In winter, snow may turn to rain after passing through ice pellets and freezing rain. |
Where does a warm front form?
Warm fronts usually form on the leading edge of a low pressure system, which is generally on the northeastern side, bringing warmer temperatures from the south, northward. On weather maps, they are defined as red half-circles that point in the direction that the front is moving.
Are occluded fronts stationary?
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. Occluded Front – a composite of two fronts, formed as a cold front overtakes a warm or quasi-stationary front.
Where is the Western Front?

What is Northern Front?
The Northern Front (Russian: Северный фронт) was a front of the Red Army during the Second World War. The Northern Front was created on June 24, 1941 from the Leningrad Military District. Its primary goal was the defense of the Kola Peninsula and the northern shores of the Gulf of Finland.
Where would you find the western front in ww1?
The Western Front, a 400-plus mile stretch of land weaving through France and Belgium from the Swiss border to the North Sea, was the decisive front during the First World War.
What occurs in a cold front?
During a cold front, a cold air mass collides with a warmer air mass. When this happens, the warmer air is less dense and therefore is thrust upward along the front. As the warm air rises, the moisture begins to condense and form clouds and precipitation.
