Cirrostratus clouds are high, thin clouds that form above 20,000 feet and are made mostly of ice crystals. They sometimes look like giant feathers, horse tails, or curls of hair in the sky. These clouds are pushed by the jet stream and can move at high speeds reaching 100 mph.

What do they indicate?

Weather Topic: What is Condensation?

Home - Education - Precipitation - Condensation

Condensation is the process which creates clouds, and therefore it is a crucial process in the water cycle. Condensation is the change of matter from a state of gas into a state of liquid, and it happens because water molecules release heat into the atmosphere and become organized into a more closely packed structure, what we might see as water droplets.

Water is always present in the air around us as a vapor, but it's too small for us to see. When water undergoes the process of condensation it becomes organized into visible water droplets. You've probably seen condensation happen before on the surface of a cold drink!
