cumulus clouds. While these fluffy-white clouds look like soft pillows of cotton, they are actually composed of small water droplets.
What does it mean when the clouds are flat on the bottom?
A: Often low clouds, like stratus and cumulus, appear to have flat bases. These clouds form as air near the ground is rising. … Meteorologists call this
altitude the lifting condensation level (or LCL)
because it is the height at which water vapor in rising air starts condensing to form cloud drops.
