They form from behind the moving cold front because the warm air condenses quickly producing clouds, rain, and stormy weather.
When a war air mass overtakes a slow moving cold air mass a warm front is created. Clouds ahead of warm front are stratiform and rainfall increases as the front approaches.
Cb or cumulonimbus clouds form at the cold font associated with heavy showers, followed by cumulus (Cu) clouds. A cold front forms when a more dense, warm air mass over a departing cold air mass
cold front
The air behind a cold front is cool and dry.
Cold Front-When a fast moving cold air mass runs into a slowly moving warm air mass Warm Front-A fast moving warm air mass collides with a slow moving cold air mass Stationary Front-When a cold and a warm air mass meet, but neither one has enough force to move the other Occluded Front-When a warm air was is caught between two cold air masses
Both, really. But they are best developed in the area of the front itself because that is typically where the greatest lift is. Ahead of the front, there is more instability so you tend to get smaller cumuloform clouds. Behind it, clouds usually move out fairly rapidly as the atmosphere quickly stabilizes, removing the lift. Refer to my link for a diagram of this.
clouds are left from the warm front

black clouds and feathered clouds
A cold front

a cold front is the fastest moving front
well clouds often form after a cold front because it is the right weather for a rainy cloud
cold front
i have no idea ocean

They don't form one, but they signal an oncoming cold front.
