Clouds form and dissipate as air circulates through the atmosphere. As air rises it
cools due to expansion which increases the relative humidity. The relative humidity
depends on the air temperature and dew point temperature. You can use an alcove in
this museum to investigate the relationships between air
temperature, dew point temperature, and relative humidity.
You can also explore the relationship between the dew point and temperature near the ground and the altitude at which a cloud will form. A discussion of the forces that generate the winds is also important to this topic. There is also an alcove on how satellite observations detect clouds in the visible and the infrared.
