Cumulus mediocris is brilliantly white when sunlit, and is dark underneath. A single pattern-based variety, Cumulus radiatus, is sometimes seen when the individual clouds are arranged into parallel rows. The resulting formations are known as "cloud streets" and are aligned approximately parallel to

Like any
Cumulus cloud, Cumulus mediocris forms via convection from thermal air columns. 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.

which could bring rain and winds. The presence of cumulus mediocris in the morning or early afternoon indicates significant instability in the atmosphere which will likely lead to
