Some research groups have also explored whether releasing certain particles could break up cirrus clouds, which trap heat against the Earth, or make low-lying marine clouds more reflective.

Both the ancient and the modern creatures have eight arms bearing suckers flanked by hairlike cirri.

This cloud may either evaporate or disappear, or it may pass to the cirrus, or sink lower and become a cirro-stratus.

The Cirrus occurs in very great variety, and in some states of the air is constantly changing.

In dry weather the cirrus is sharp, defined, and fibrous in texture, the lines vanishing off in fine points.
