What type of front makes temperatures plummet?
A cold front's location is at the leading edge of the temperature drop off, which in an isotherm analysis would show up as the leading edge of the isotherm gradient, and it normally lies within a sharp surface trough. Cold fronts move faster than warm fronts and can produce sharper changes in weather.
What kind of weather happens during a cold front?
Winds increase stronger as the cold front passes. A significant drop in temperature occurs, as well as heavy rain, occasionally accompanied by hail, thunder, and lightning. At the front, atmospheric pressure shifts from decreasing to increasing.
What type of weather is associated with a warm front?
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. |
What are the 4 types of fronts and how do they affect the weather?
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.
What occluded front?
In meteorology, an occluded front is a type of weather front formed during cyclogenesis. The classical and usual view of an occluded front is that it initiates when a cold front overtakes a warm front near a cyclone, such that the warm air is separated (occluded) from the cyclone center at the surface.
What are the three types of weather 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 happens when a cold front happens?
As the cold front passes in your area, a sudden drop in temperature will occur, with the winds building and shifting. The rain will increase and may contain a mixture of hail, lightening and thunder. Cumulonimbus clouds are common in a passing cold front, with the large clouds extending high into the sky.
What type of weather is occluded front?
Weather associated with an Occluded Front A wide variety of weather can be found along an occluded front, with thunderstorms possible, but usually their passage is associated with a drying of the air mass. Rarely, cold core funnel clouds are possible if shear is significant along the cold front.

How do occluded fronts affect weather?
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.
What happens in a warm front?
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.
What weather do occluded fronts bring?
The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward. Such fronts can bring strong winds and heavy precipitation.
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 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 causes weather fronts?
The answer is "moisture and differences in air pressure." A front represents a boundary between two different air masses, such as warm and cold air. If cold air is advancing into warm air, a cold front is present. On the other hand, if a cold air mass is retreating and warm air is advancing, a warm front exists.
What happens at a cold front quizlet?
A cold front forms where cold air moves under warm air, which is less dense, and pushes the warm air up. Cold fronts can move quickly and bring thunderstorms, heavy rain, or snow.
What is an occluded front in weather?
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.
How are weather fronts named?
A front takes its name from two places. It is the literal front, or leading edge, of air that's moving into a region. It is also analogous to a war battlefront where the two air masses represent the two clashing sides.
What happens during a cold type occluded front?
At an occluded front, the cold air mass from the cold front meets the cool air that was ahead of the warm front. The warm air rises as these air masses come together. Occluded fronts usually form around areas of low atmospheric pressure.

What weather is occluded front?
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. Such fronts can bring strong winds and heavy precipitation. Occluded fronts usually form around mature low pressure areas.
What is occluded weather?
In meteorology, an occluded front is a type of weather front formed during cyclogenesis. The classical and usual view of an occluded front is that it initiates when a cold front overtakes a warm front near a cyclone, such that the warm air is separated (occluded) from the cyclone center at the surface.
How weather fronts affect the weather?
The presence of a warm front means that warm air is advancing and rising over cold air. This is because warm air is 'lighter,' or less dense than cold air. Warm air is replacing cooler air at the surface. The edges of the 'suns' indicate the direction of movement of the warm air.
What happens during a cold front and why?
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.
What is a weather front quizlet?
Weather Front. A boundary that forms when air masses meet that have different temperature, pressure, and humidity conditions. Warm Front. Forms when warm air slides up and over a cold air mass; it brings gentle rain or light snow followed by warmer weather.
What is a weather 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 is an air front?
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.
What kind of weather does occluded front bring?
Occluded front weather conditions An occluded front would likely bring rain or snow, depending on the air temperature. The intensity of the precipitation depends on which of the two air masses is colder, the one in front or the one behind.
What occurs at an occluded front?
As the storm intensifies, the cold front rotates around the storm and catches the warm front. This forms an occluded front, which is the boundary that separates the new cold air mass (to the west) from the older cool air mass already in place north of the warm front.
What is a cold front quizlet?
cold front is defined as the leading edge of a cooler and mass of air, replacing (at ground level) a warmer mass of air. Cold front. A weather front is a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena. Front. You just studied 15 terms!
