Solar Pillar

A solar pillar is an optical phenomenon that occurs when ice crystals suspended in the atmosphere reflect upwards light coming from the sun low on the horizon.

Alone solare

Un alone (dal greco antico ἅλως ( hálōs ) 'aia, disco') è un fenomeno ottico prodotto dalla luce (tipicamente proveniente dal Sole o dalla Luna) che interagisce con i cristalli di ghiaccio sospesi nell'atmosfera . Gli aloni possono avere molte forme, dagli anelli colorati o bianchi agli archi e alle macchie nel cielo. Molti di questi compaiono vicino al Sole o alla Luna , ma altri si verificano altrove o addirittura nella parte opposta del cielo. Gli aloni solari sono anche chiamati Sun dog, Sunbow o Whirling Rainbow.

Hey isn't it interesting that on a rainbow yellow green and orange are right next to each other but purple isn't

How Rainbows Form pt. 2

To add to a previous post, this one explains how rainbows appear to us as half-circles!

Ok, so other than the dispersion of light in raindrops, another factor in the occurrence of rainbows is seeing them. We do not see every individual rainbow formed from each droplet because we’re too far away to see them. Instead, we see different individual colors from different raindrops based on their height and angle from us. 

A raindrop at a 42-degree angle from us relative to the sun would reflect red light to us and end up looking red. The other raindrops below it would look orange, yellow, green, blue, and indigo in the angles between 40 and 42 degrees. Violet would be below the other colors at a 40-degree angle from us and the sun.

This would also explain why we see rainbows as an arc or half-circle. According to Wikipedia, “A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the center”.

The sun shines light on many points at once from its direction. For an observer to be able to see colors from a rainbow, the dispersed light reflected from the sun would have to reach them from an angle. This means that all the other raindrops reflecting colors to the observer would also have to reach their eyes at 40-42 degree angles, which also leads to all the points (in this case, raindrops showing color) being at similar distances away from the observer.

 To make this easier to understand, I tried to use a triangle ruler where the lines (base and hypotenuse) represented the path of the light from the sun to the observer’s eyes; the point of the triangle touching the ground would represent the observer.

 If the triangle was tilted so that the point on the bottom stayed in its place, it would go in the direction of an arc. If all the points on this arc were mapped out, it would form a half-circle or at least part of one. 

It would form a full circle if no ground or horizon were blocking the triangle ruler. This is the same for rainbows. Rainbows are full circles, but the lower half is usually blocked by the ground or horizon. This is also the reason why people on airplanes or in the sky can sometimes see rainbows as circles because the horizon does not block them.

Rainbows are also similar to mirages since they’re a result of the behavior of light, so unfortunately you can’t ride them or find any gold at the end. Additionally, the rainbow will move with you because only certain raindrops can form the rainbow you see depending on your position and location; Buttttt! this also means that everyone sees a different rainbow, which makes each rainbow as unique as the observers who look at one :) even though it may not look that way at first glance

I’m gonna stop writing about rainbows now but I hope this and the other post were good explanations for the formation of rainbows!

Light pillars

Light pillars is a natural optical phenomenon. It is an admirable and relatively common thing to see in the sky. These columns of light appear to beam upwards from unshielded lights and create an incredible view. Light pillars are most often seen during sunsets and sunrises. They can reach a height of 5° to 10° and sometimes even higher.

This phenomenon is caused by the reflection of light from horizontal surfaces arranged horizontally by the free fall of flake ice crystals.

The appearance of a column of light depends on its formation and the direction of incidence.

Aphra has dark skin and long hair with two white braids and one black one, and they are wearing a flowy teal dress. There is a gold halo behind their head. There are patches of polemoniums in the grass and Aphra is carrying a handful lifted up by their face. The sky is a radiant display of halos and sunrays, and a colorful swirl is splitting the sky open to show a starry night in the bottom left corner. Aphra is looking off to the side and smiling.

so on wednesday i went storm chasing with my friend and as we were watching a storm to Maybe Perhaps do something rain came in. and i just got my ratty puma windbreaker from god knows what year and put it over my head and as my friend cackled said: "feeling very philip seymour hoffman in twister (1996) in this"

picture for reference but picture this in the middle of nowhere in germany on a day where the storms aint stormin' for the full effect
