If a weather front becomes stationary, so that the density contrast across the its boundary vanishes, it can degenerate forming a shearline, which separates areas of differing wind velocity.

What is a tailend of a cold front?
A weather disturbance in the Philippines (the tropics) which normally occurs during the winter season. It is composed of multicell thunderclouds (provides precipitation and thunderstorms) which forms along the shearline that is connected to the cold front. The greater difference in temperature (temperature gradient) during winter is the reason why this disturbance forms and is also amplified by wind convergence.
Why does a stationary front stay in the same place?
Fronts become stationary because the stationary front is like a stand-off between a cold front and a warm front. The warm front is trying to get on top of the warm front and make a warm front, while the cold front tried to avance on the warm front. Neither are successful, so they just stand there waiting for each other to move and one to become dominant. They stay where they are until one other front pushes them away.
What is a wind front?
A weather front is a boundary separating two masses of air of varying densities. The two kinds of weather front are a cold front and a warm front.A weather front is a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena. In surface weather analyses, fronts are depicted using various colored lines and symbols, depending on the type of front. The air masses separated by a front usually differ in temperature and humidity. Cold fronts may feature narrow bands of thunderstorms and severe weather, and may on occasion be preceded by squall lines or dry lines. Warm fronts are usually preceded by stratiform precipitation and fog. The weather usually clears quickly after a front's passage. Some fronts produce no precipitation and little cloudiness, although there is invariably a wind shift.[1] Cold fronts and occluded fronts generally move from west to east, while warm fronts move poleward. Because of the greater density of air in their wake, cold fronts and cold occlusions move faster than warm fronts and warm occlusions. Mountains and warm bodies of water can slow the movement of fronts.[2] When a front becomes stationary, and the density contrast across the frontal boundary vanishes, the front can degenerate into a line which separates regions of differing wind velocity, known as a shearline. This is most common over the open ocean.
What is shearline on boats?
the generally curved shape of the top of the hull. The sheer is traditionally lowest amidships to maximize freeboard at the ends of the hull. Sheers can be reverse, higher in the middle, to maximize space inside or straight or a combination of shapes.

How can you tell the direction a front is moving?
Cold fronts and occluded fronts generally move from west to east, while warm fronts move poleward. Because of the greater density of air in their wake, cold fronts and cold occlusions move faster than warm fronts and warm occlusions. Mountains and warm bodies of water can slow the movement of fronts.[2] When a front becomes stationary, and the density contrast across the frontal boundary vanishes, the front can degenerate into a line which separates regions of differing wind velocity, known as a shearline.

Is a warm front mass of warm air that moves into a region that has cooler air?
