More About Clouds

What Are Clouds Made Of?

Clouds are really nothing more than water vapor that condenses into visible form. Usually moisture filled air is lifted into the atmosphere by an incoming air mass or simply by the heat of the sun. As this parcel of air is lifted, the pressure drops and the air is cooled. The combination of the dropping pressure and cooling air water vapor to condense and form clouds.



Do Clouds Come In Different Colors?

Clouds do appear to come in different colors. It is the processes of reflection and absorption that create the shades and colors we see in clouds. Colors can range from white to black and yellow to red. Some clouds even display a greenish tinge. What do these colors tell us about clouds and weather? That depends on the color.

• White Clouds
• Blue or Grey Clouds
• Green Clouds
• Red Clouds
• Yellow Clouds

How Much Does a Cloud Weigh?

We estimate cloud weight in cubic kilometers. A cubic kilometer is a cube which is .6 miles on each side.

It is said that low stratus clouds can weigh as much as 200,000 pounds. If that impresses you, take a good look at the next large cumulonimbus cloud that looms over your head. Scientists tell us these clouds can weigh as much as two million pounds!!

Yes, I said TWO MILLION POUNDS hang above the earth in some of these giant storm clouds. Better not forget the umbrella!
