Cirrus clouds are
atmospheric clouds characterized by thin, wispy strands, often bunched into tufts. They range in color from white to a faint gray and form when water vapor undergoes
deposition at altitudes above 5,000 m (16,500 ft) in temperate regions and above 6,100 m (20,000 ft) in tropical regions. They also form from the outflow of
tropical cyclones or the
anvils of
cumulonimbus clouds. Since these cirrus clouds arrive in advance of the
frontal system or
tropical cyclone, they indicate that the weather conditions may soon deteriorate. While they indicate the arrival of precipitation, cirrus clouds themselves produce only fall streaks (falling ice crystals that evaporate before landing on the ground).
Jet stream-powered cirrus clouds can grow long enough to stretch across continents, but they remain only a few kilometers deep. When visible light interacts with the ice crystals in cirrus clouds, it produces
glories,
sundogs, and
fire rainbows. Cirrus clouds raise the temperature of the air beneath them by an average of 10 °C (18 °F). (

1962 – Alouette 1, Canada's first satellite, and the first satellite constructed by a country other than the Soviet Union or the United States, was launched.
1963 – The University of East Anglia was founded in
Norwich, England, after talk of establishing such a university in the city began as early as the 19th century.
