Give the upper atmosphere dust, and it will make cirrus clouds. It has long been a mystery exactly what causes the formation of cirrus clouds, the wispy billows of ice that can be seen high in the ...

The advantage of the CATS data, seen in orange in this image, is that it provides a 3D view of cirrus clouds. The clouds span from about 33,000 feet to 43,000 feet (10 to 13 kilometers).

The cloud forms that appear highest in the sky are cirrus, cirrocumulus, and cirrostratus, and they appear above 20,000 feet. Some clouds can be challenging to identify because they appear ...

Cirrus clouds are found high in the atmosphere where most jet planes fly, between 20,000 and 40,000 feet. Temperatures are well below zero degrees Fahrenheit, so these clouds are formed with ice ...

Cirrus clouds generally form by the time humidity reaches about 100%, Cziczo said. But under the colder, Martian conditions, the clouds didn’t form until humidity reached a whopping 190%.
