Vertical draft

An updraft or downdrafts is the vertical movement of air as weather causes two forces to move.

Updrafts lead to the formation of clouds.
Clouds that form in the air are called updrafts, known as converging air, are caused by the dew point. Warm water evaporates, then condenses, forming clouds. 

From the dew point, the water can evaporate to gas, called  water vapor. Visible or invisible gas rises to the air, forming these cotton candy-like white or gray clouds in the air. 

Evaporation
Evaporation is caused by: 
1. Solar energy
2. Kinetic energy

Condensation
After the warm, moist air reaches the atmosphere, it transforms. Condensation occurs when warm, moist air reaches where the clouds are, the air cools down then becomes a cloud. 

Cirrus cloud
Cumulus cloud
Stratus cloud

Precipitation clouds
Cumulonimbus cloud
Nimbostratus cloud

Middle-altitude clouds
Altocirrus cloud
Altocumulus cloud
Altostratus cloud

Dew point
Dew points depend on evaporation and the point that something freezes, might be the most important item, the dew point is affected on air humidity, the more moisture, the higher the dew point.
