When a warm or cold front stops moving, it becomes a stationary front. Once this boundary resumes its forward motion, it once again becomes a warm front or cold front.
Stationary fronts may bring several days of clouds and precipitation as air is constantly forced to rise, and multiple low pressure systems can move over the frontal boundary bringing with it rain, snow, and potentially wind.
Cold fronts are most often associated with severe thunderstorms and tornadoes, but such storms can form along warm fronts, stationary fronts, and dry lines.
warm
There are four types of fronts that will be described below: cold front, warm front, stationary front, and occluded front.To locate a front on a surface map, look for the following:sharp temperature changes over relatively short distances,changes in the moisture content of the air (dew point),shifts in wind direction,low pressure troughs and pressure changes, andclouds and precipitation patterns.Cold fronts tend to be associated with the most violent weather among all types of fronts.Cold fronts tend to move the farthest while maintaining their intensity.Warm fronts are typically less violent than cold fronts.Although they can trigger thunderstorms, warm fronts are more likely to be associated with large regions of gentle ascent (stratiform clouds and light to moderate continuous rain).Stationary front- a front that does not move or barely moves.Stationary fronts behave like warm fronts, but are more quiescent.Many times the winds on both sides of a stationary front are parallel to the front.Typically stationary fronts form when polar air masses are modified significantly so as to lose their character (e.g., cold fronts which stall).Occluded fronts are indicative of mature storm systems (i.e., those about to dissipate).The most common type of occlusion in North America is called a cold-front occlusion and it occurs when the cold front forces itself under the warm front. The weather ahead of the cold occlusion is similar to that of a warm front while that along and behind the cold occlusion is similar to that of a cold front.
Warm fronts are generally associated with relatively calm weather. Rain showers are common. Thunderstorms may occur, but not usually.
They all cause a change in weather.

A Cold Front, Warm Front, Stationary Front, and Occluded Front.
Cold fronts cause violent weather, including heavy rain, strong winds, and thunderstorms.
