Cirrus clouds are high-altitude clouds ... Unlike typical clouds, which are formed from water droplets or ice crystals, noctilucent clouds are made up of tiny ice crystals formed around dust ...

As temperatures rise, clouds like stratus, cirrus and cumulonimbus are changing – becoming higher or less extensive. These ...

Halos form around the sun or the moon whenever their light passes through ice crystals in high-level cirrus clouds. These crystals act like a prism, bending that light at an angle of 22° angle ...

At these heights, the atmosphere is cold enough that clouds are typically composed of ice crystals, not water droplets. These ...

We’ve seen this across our viewing area almost looking like a rainbow in the clouds so how does a Sunday form? Sunlight hits ice particles in the atmosphere mainly associated with cirrus clouds.

Decades-long efforts to improve air quality, combined with sustained emissions, may be altering how clouds are formed, by altering the volumes of aerosols and other particulate matter in the ...

Professor Toon has helped conceive, develop and lead many NASA airborne field missions aimed at understanding stratospheric volcanic clouds, stratospheric ozone loss, the effects of aircraft on the ...

The results compare favourably with observations and support interpretations of insitu, satellite and lidar observed aviation impact on cirrus clouds. CoCiP can be used to predict and minimize the ...
