What is a weather front?
A stationary front (or quasi-stationary front) is a weather front or transition zone between two air masses when each air mass is advancing into the other at speeds less than 5 knots (about 6 miles per hour or about 9 kilometers per hour) at the ground surface.
Sep 6, 2024 · A stationary front is a frontal system that forms at a fixed location when two air masses meet, but neither is strong enough to replace the other. If one air mass gains strength or the wind direction changes, it starts to move again as either a cold or warm front, depending on the dominant air mass.
Jan 3, 2016 · When the surface position of a front does not change (when two air masses are unable to push against each other; a draw), a stationary front is formed. The wind motion on both sides of the front is parallel to the front. Warm or cold front stops moving, so the name stationary front.
A stationary front is a weather boundary that occurs when a warm air mass and a cold air mass meet, but neither is strong enough to replace the other. This results in a prolonged period of weather activity at the front, often leading to clouds and precipitation that can last for days or even weeks.
A front may become stationary if an air mass is stopped by a barrier, such as a mountain range. A stationary front may bring days of rain, drizzle, and fog. Winds usually blow parallel to the front, but in opposite directions.
Stationary fronts are alternating warm and cold front symbols on opposite sides, indicating no movement. A portion of a simplified weather map is shown in Figure \(\PageIndex{4}\). The map depicts a wave cyclone as it is starting to occlude.
