Front (meteorology)

Cloud wall (signs of a fast moving cold front)

Warm and cold fronts in a low pressure area

In meteorology, a front is an abrupt boundary between different air masses , combined with comparatively sudden changes in air pressure , temperature and wind direction . Characteristic changes in cloud formations and weather conditions also occur here, with the spatial scale of these changes being very variable and essentially depending on the type of front. If the front is spatially strongly bound, so it hardly shifts or not, one also speaks of a stationary front . The area in which fronts tend to occur is called the frontal zone .
