POLAR RAINBOWS - intimate nacreous clouds (polar stratospheric clouds) timelapse 4K

👉 Please consider supporting my channel by buying us a virtual coffee at: ​ After 35000 pictures, 4 days of filming, 1000 km roadtrip, 64 finished timelapse sequences and 200 Gb of data, I am extremely proud to unveil this sizzle reel featuring the gorgeous nacreous clouds displays we had from Jan 23rd into January 27th over northern Scandinavia. Those are some of the most detailed, colored and intimate shots of polar stratospheric clouds taken to date and seen in timelapse. You can actually see how they form and evolve over the course of several dozens of minutes and how their mesmerizing colors change overtime depending on the angle of sunlight refraction and their shape/thickness. Shooting locations included Malangen (Norway), Skibotn (Norway) and the Kilpisjärvi area (Finland). All was shot on the Canon R, Canon 6D and Sony a7sIII with various focal lengths (20, 24, 50, 85, 200-600mm). PSCs are also called mother-of-pearl clouds or nacreous clouds because their iridescence (diffraction of sunlight in tiny ice particles) is some of the strongest in clouds on Earth. Their strong colors are very visible with naked eyes, making the experience surreal, almost straight out of a fairy tale. They are also some of the highest clouds on Earth, forming around 15-30km in altitude in very precise conditions, limiting their occurrence. It needs to be extremely cold up there (below 78°C), which can only be satisfied in the winter months above polar regions where the stratosphere is at its coldest. There, tiny ice particles (along with other chemicals present in type I) nucleate and form over mountain ranges because of vertical shears/strong winds to form lenticular structures (type II).
