How is a front defined in terms of weather?

Answer 1

In meteorology, a front is a boundary between two air masses, which can't mix each other due to their properties like their temperature, their pressure and their relative humidity. A front is associated with a low pressure system, a system where the atmospheric pressure is lower than the surrounding areas. There are several types of fronts, which have different properties in the cloud and precipitation formation such as the warm fronts, the cold fronts, the stationary fronts, the occluded fronts and some others. A warm front is a type of meteorological front where the warm air mass comes up on the cold air mass. The warm, light and dilated air goes over the cold, heavy and dense air. The warm front is associated with covered weather and sometimes rainy, usually with high clouds such as cirrus which will become nimbostratus or altostratus. A warm front is associated with warm, cloudy weather (sometimes moderated rainy) and with an atmospheric pressure decreasing progressively. A cold front is a type of meteorological front where the cold air mass comes down under the warm air mass. The cold, heavy and dense air goes under the warm, light and dilated air. The cold front is generally associated with cirrocumulus and altocumulus and the clouds are rarely high in the sky. Behing a cold front, there is clear skies and sunny weather because there is usually a high pressure system behind a cold front. But clear skies also follow warm fronts. Cold fronts tend to move faster than warm fronts because the cold air is denser than the warm air and is harder to move. Globally, all the fronts are associated by a change in the weather, which is more brutal in cold fronts than in warm fronts.

Answer 2

It means that a front of air moving in one direction is moving to your area. It can be either a cold front or a warm front, which means that either cold air or warm air is moving in one direction to your area.

Answer 3

It actually comes from the military "front", meaning the line where the two sides meet and battle. This is comparable to a front in the weather, which is the boundary where two opposing air masses clash.

Answer 4

it is when a cold front ( cold air) moves in front of a warm front (warm air) or vice versa

Answer 5

A weather front is a boundary that separates two masses of air that have different densities. This is the main cause of most weather events.

Answer 6

The cold front is basically the leading edge of a cooler mass of air The cold front passing over usually brings some rain.

It is found in a low pressure weather system (a depression).
