Definition: A stationary front can be considered a stalled front. There is little forward movement in a stationary front. Often, the weather will remain the same for days if a stationary front stays over an area.
Winds move parallel to the frontal boundary, but in opposite directions on either side of the transition zone. Once a stationary front begins to move again, it resumes the characteristics of either a warm or cold front. The weather map symbol used is a combination of the red semicircles used for warm fronts and the blue triangles used for cold fronts.
Sometimes, a stationary front is moving at a very slow, but measurable rate. At this point, the front is called a quasi-stationary front.
