What is a warm occluded front?

Asked by: Bob Tunnell

What happens in a warm occluded front?

In a warm occlusion, the cold air mass overtaking the warm front is warmer than the cool air ahead of the warm front, and rides over the colder air mass while lifting the warm air.

Is an occluded front warm or cold?

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 is a cold 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 kind of weather comes with an occluded front?

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’s the meaning of warm front?

A warm front is the boundary between a mass of warm air and a retreating mass of cold air. At constant atmospheric pressure, warm air is less dense than cold air, and so it tends to override, rather than displace, the cold air.

Do occluded fronts cause thunderstorms?

A thunderstorm is a storm that produces thunder and rain, on average lasting about 30 minutes and averaging about 15 miles in diameter. There are four types of weather fronts that cause thunderstorms: cold front, warm front, stationary front and occluded front.

What is a characteristic of warm fronts?

Warm fronts typically travel between 10 and 25 miles per hour and contain warm, humid air. As the warm air is lifted, the temperature drops and condensation occurs, forming clouds. Warm fronts typically have a gentle slope, so the warm air rising along the frontal surface is gradual.

What is warm front and cold front?

Basically, a weather 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.

How would you describe an occluded front?

Occluded fronts get their name from the fact that when the cold air pushes underneath the warm air, it lifts the warm air up from the ground, which makes it hidden, or “occluded.” Occluded fronts usually form with mature low pressure areas. They act like both warm and cold fronts.
