Circumzenithal arc in contrail
Contrail usually consists of tiny hexagonal plate ice crystals with plate orientation. It's easy to find sundog, circumzenithal arc, and circumhorizontal arc in contrail, although they cannot appear at the same time.
A circumzenithal arc is a phenomenon where light from the sun reflects through ice crystals instead of rain in the atmosphere, causing it to appear upside down.
In trailers 2 and 4, a circumzenithal arc can be seen hanging there in the sky.
A rainbow usually occurs when an almost LOCAL shower of rain falls from the sky, and the light reflects trough the rain drops, acting as a prism and creating a rainbow. They occur when raining and they remain there afterwards for a little while.
How does this tie into Death Stranding? Well, after having been introduced to timefall, which is rain from another world, I believe that the circumzenithal arc is created when light reflects through timefall rain.
There are tons of references to the βupside-down worldβ and βparallel worldsβ, where the Chirals world is the upside down version of ours, it would make sense that the arc is created through light reflecting through other worldly rain.
How does it tie into gameplay? Well, the circumzenithal arcs will be an indication or almost a beacon to inform the player that around that area, timefall fell and the Chiral beings were present there not to long ago. This will aid the player, who as a delivery guy who traverses the world, in avoiding that area for a safer route.
Also, when humans breathe in the world, the air around them is cold as there breath condenses when they exhale. This could be another reason why they form.
What do you guys think?
