'''Cumulus''' clouds, distinguished by their puffy appearance, form from the condensation of water vapor in areas where [[convection]] occurs.  As parcels of air are heated, they rise because of [[buoyancy]].  As the air rises, it becomes cooler.  When the air reaches the [[dewpoint]], water vapor [[condense]]s into droplets, which form a cloud.  The [[condensation]] of the water vapor, however, causes the air to become warmer; if atmospheric conditions are [[instability|unstable]], cumulus clouds may attain great vertical development.  The base of a cumulus cloud is typically well below 8000 feet above sea level, but the height of the top of cumulus a cloud may vary greatly.  The larger or taller a cumulus cloud, the more likely it is to produce precipitation or to develop into a [[cumulonimbus]] cloud, which may produce a [[thunderstorm]] or [[severe weather]].
