Cloud iridescence
Cirrocumulus floccus
High altitude convection cloud consisting mostly of ice crystals, Cirrocumulus floccus, at sunset during mid-summer.
Supercell
On a wild stormy day for South Australia, with 423,000 lightning strikes hitting the state, this supercell rotating updraft thunderstorm formation was seen over Nilpena Station.
Altocumulus Undulatus clouds at dawn
Lunar iridescence through Cirrocumulus clouds
High altitude Cirrocumulus clouds are formed of supercooled water droplets and ice crystals which can diffract light, such as in this instance of lunar iridescence.
Vapour trail
Vapour trails, or contrails, are high altitude linear clouds generated by engine exhaust or changes in air pressure from aircraft flight paths, composed primarily of ice crystals. Seen here crossing the path of a waning crescent moon during a colourful Flinders Ranges dawn in autumn.
