What do cirrus clouds bring?

Clouds are white because their water droplets or ice crystals are large enough to scatter the light of the seven wavelengths (red, orange, yellow, green, blue, indigo, and violet), which combine to produce white light. Why do clouds turn gray? Clouds are made up of tiny water droplets or ice crystals, usually a mixture of both. read more

Cirrus (cloud classification symbol: Ci) is a genus of atmospheric cloud generally characterized by thin, wispy strands, giving the type its name from the Latin word cirrus, meaning a ringlet or curling lock of hair. This cloud can form at any altitude between 16,500 ft (5.0 km) and 45,000 ft (14 km) above sea level. read more

Cirrus clouds are the most common of the high clouds. They are composed of ice and are thin, wispy clouds blown in high winds into long streamers. Cirrus clouds are usually white and predict fair to pleasant weather. read more

Cirrus clouds are the highest of the tropospheric clouds and can be see from a great distance. As a result, small systems that are close may produce cirrus and look like large distant systems. Also, the direction of the system's movement is not obvious from a short glance. The jet stream will often have cirrus clouds associated with it, too. read more

Balloon-carried hygrometers give information on the humidity of the cirrus cloud but are not accurate enough to measure the depth of the cloud. Radar units give information on the altitudes and thicknesses of cirrus clouds. read more
