Cumulus Cloud Train

This a category of cumulus clouds and specially known as Cumulus mediocris. Such clouds are formed via convection of thermal air columns. It is a low to middle level cloud with some vertical extent. Pockets of air warmer than the air around them (due to ground surface irregularities or other factors) are also less dense than the air around them, and are buoyant.
As the air pockets float upwards, they cool, eventually reaching their dew point and condensing, forming Cumulus humilis clouds. If the thermals are powerful enough, they will continue to push air upwards and the Cumulus humilis clouds will develop into Cumulus mediocris clouds.
