A STATIONARY front forms when a cold front or warm front stops moving. This happens when two masses of air are pushing against each other but neither is powerful enough to move the other.

• The situation can be described winds blowing parallel to the front instead of perpendicular can help it stay in place.

The exact weather of a stationary front depends greatly on the characteristics of its constituent air masses - their moisture levels, for example - and the general instability of the local atmosphere. Often, however, conditions resemble those encountered along warm front weather: extensive cloudiness and continuous rain. A wide area of precipitation can be expected on the cold-air side.

Since there is little frontal movement, weather conditions are likely to be comparatively quiet, though longer lasting.
