What type of weather 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. Can bring strong winds and heavy precipitation. Similarly, what happens in an occluded front? In meteorology, an occluded front is a weather front formed during the process of cyclogenesis, when a cold front overtakes a warm front.

When this occurs , the warm air is separated occluded from the cyclone center at the Earth's surface. There are four types of fronts that will be described below: cold front, warm front, stationary front, and occluded front. Asked by: Kaneez Janetzki asked in category: General Last Updated: 19th May, What type of weather is associated with an occluded front? Occluded fronts usually form around areas of low atmospheric pressure. There is often precipitation along an occluded front from cumulonimbus or nimbostratus clouds.

Wind changes direction as the front passes and the temperature changes too. The temperature may warm or cool. What does a warm front look like? A warm front is defined as the transition zone where a warm air mass is replacing a cold air mass. Warm fronts generally move from southwest to northeast and the air behind a warm front is warmer and more moist than the air ahead of it. On colored weather maps, a warm front is drawn with a solid red line.

What causes a weather front? A weather front is a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena outside the tropics. Because of the greater density of air in their wake, cold fronts and cold occlusions move faster than warm fronts and warm occlusions. Do occluded fronts cause tornadoes? A cold occlusion takes place when the air on the back side of the front is is colder than that ahead of it.

With this type of occluded front, it acts as if it is a cold front. Cold fronts are responsible for the strong, severe storms that can produce damaging winds, hail and tornadoes. How do you identify an occluded front? They move fast, up to twice as fast as a warm front.

As a cold front moves into an area, the heavier more dense cool air pushes under the lighter less dense warm air, causing it to rise up into the troposphere. Lifted warm air ahead of the front produces cumulus or cumulonimbus clouds and thunderstorms, like in the image on the left A.

As the cold front passes, winds become gusty. There is a sudden drop in temperature, and also heavy rain, sometimes with hail, thunder, and lightning. Atmospheric pressure changes from falling to rising at the front. After a cold front moves through your area, you may notice that the temperature is cooler, the rain has stopped, and the cumulus clouds are replaced by stratus and stratocumulus clouds or clear skies. On weather maps, a cold front is represented by a solid blue line with filled-in triangles along it, like in the map on the left.

The triangles are like arrowheads pointing in the direction that the front is moving. Notice on the map that temperatures at the ground level change from warm to cold as you cross the front line. A side view of a warm front A, top and how it is represented on a weather map B, bottom. A warm front forms when a warm air mass pushes into a cooler air mass, shown in the image to the right A. Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms.

Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth's surface.

Warm fronts often form on the east side of low-pressure systems where warmer air from the south is pushed north. You will often see high clouds like cirrus, cirrostratus, and middle clouds like altostratus ahead of a warm front.

These clouds form in the warm air that is high above the cool air. As the front passes over an area, the clouds become lower, and rain is likely. There can be thunderstorms around the warm front if the air is unstable. On weather maps, the surface location of a warm front is represented by a solid red line with red, filled-in semicircles along it, like in the map on the right B.

The semicircles indicate the direction that the front is moving. They are on the side of the line where the front is moving. Notice on the map that temperatures at ground level are cooler in front of the front than behind it. Instead, they form a front, usually hundreds of miles long. 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. Such fronts can bring strong winds and heavy precipitation. The occlusion process discussed above follows the original Norwegian Cyclone Model with the formation of an occluded front simply as a result of surface frontal movements.
