chris82 Posted February 1, 2016 Share Posted February 1, 2016 Tonight i seen for the first time ever some Nacreous "mother of pearl" clouds. Also known as polar stratospheric clouds. These clouds are 15-30km (10-20 miles) up in the stratosphere. They form in the freezing temps of the lower stratosphere at temps below -80ºc. Formed of nitric acid and ice crystals and lit when the sun is below the horizon. They look incredible but they have a downside. Their chemical composition assists the production of chlorine which in turn contributes to the depletion of the ozone layer. These were taken from my kitchen window as i was just getting home from work when i first noticed the clouds . Welcome, dear visitor!
