A stationary front (or quasi-stationary front) is a weather front or transition zone between two air masses, when neither air mass is advancing into the other at a speed exceeding 5 knots (about 6 miles per hour or about 9 kilometers per hour) at the ground surface. On weather maps, it is shown by a solid line of alternating blue spikes pointing to the warmer air mass and red domes pointing to the colder air mass. If your talking about a weather front Hope this helped.
