Cumulus Cloud

The puffy white cloud that looks like everything and weighs nothing... right?/Weather & Climate

A typical cumulus cloud -- the fluffy, flat-bottomed variety you drew as a child -- contains roughly 500,000 kilograms of water in the form of tiny suspended droplets. That is about 500 metric tons floating overhead, held aloft by updrafts of warm air. The average cumulus spans about a kilometer across and occupies a billion cubic meters of sky at an altitude of around 2,000 meters. They form and dissolve in minutes to hours, which is a lot of drama for something that is 99.99997% air.
