Mother Nature at her finest, creating this magical effect in the sky. This effect is caused by the collision of solar winds and the magnetospheric charged particles high in the atmosphere - named Aurora. These lucent curtains are just amazing, making long and silent night flights much more entertaining ;)
Flying steady at 31.000ft above St. Petersburg where the sun will not really set, since our routing is quite northern. The ‘clouds’ you can see aren’t the clouds you will be able to see on a regular day or night. These Noctilucent Clouds are formed by dust and ice particles high in the atmosphere (at altitudes of about 80km), illuminated by the sun from below the horizon - thus creating this quite magical effect both on the left and right of the windscreen.
That’s a lot of water droplets combined in a massive Cumulonimbus cloud somewhere over the US of A. These massive clouds can produce dangerous severe weather such as thunderstorms, hail and gusts. This Cumulonimbus is characterized by the anvil-like shape, caused by the temperature inversion at the tropopause. It’s probably bullying some people over there.
We just departed from Houston - Texas, climbing to our initial altitude of 31.000 feet. In the meantime, Mother Nature was busy creating all those magnificent clouds, resulting in a beautiful sky. And a rather dangerous sky as well, as most of those clouds are Cumulonimbus clouds which hold thunderstorms.
This is Holland, 100% Holland! Lots and lots of polders, small towns, its fleecy clouds. But.. I am not wearing any wooden shoes and this picture isn’t taken from top of a windmill. Right here we are on a long final for runway 06 - the Kaagbaan - at Schiphol.
