Stationary
jagged
a solid surface
Rough surface provides lot of friction.
a stationary front,but it will sometime move eventually.
if the mass is more than the friction is high. and if the surface is rough then also the friction is more. thus we can say that both mass and surface type affects friction.
I believe it is a cold front
It is frontal rainfall

A cold front.

This type of weather front is found at a homogenous warm air mass's leading edge. It is found at the isotherm gradient's equatoward edge, and is typically found in a broader trough of low pressure. This type of front moves far slower than cold fronts do. This also results in the temperature differences across, or throughout a warm front to be broader overall, in scale. As the front approaches, rainfall gradually increases, and the clouds preceding the warm front are most often stratiform. Preceding a warm frontal passage, fog can also occur. After a frontal passage, warming and clearing is typically rapid. Thunderstorms can be deposited amidst stratiform clouds preceding the front, and the thundershowers can continue after the frontal passage, if the mass of warm air is unstable.
