the eerie sky

Something interesting has recently

happened in South Dakota.It was all over

the Internet, so perhaps you heard

about it in July 2022. the sky in this

state suddenly turned green, so what it caused by a human

or by nature.

Tuesday, July 5th, 2022, shortly after a

a heavy storm in the sky over South Dakota in

The U.S. was still overcast.

They'd never seen anything like that.

Before. People said that it looked like

something straight up from science

fiction or even a horror movie.

Unsurprisingly, South Dakotans

immediately started spreading the news.

All over social media, people shared

their beautiful yet very eerie images.

On Twitter, they showed the sky over the city of Sioux Falls and a few other towns.

Even though it may look like something scary.

In reality, this is not a

terrifying phenomenon all; it's a

a simple play of the light and the

atmosphere, something like this happens rarely and usually means that bad weather is approaching.

That's also true considering what happened in

South Dakota just before people started

But why isn't this all over the news?

That may be due to the occurence being usual for the residents.Thunderstorms occur very often in the

An exception was the so-called Derecho storm.

It is widespread and long-lived. it's

a combination of a fast-moving

group of severe thunderstorms and

downpours.

People often say that a derecho is as

strong as a tornado, but still, there's a

difference between them A tornado is a

vortex, a rotating column of air,

usually about 500 feet in diameter.

If we compare a derecho to an ordinary

It wasn't any different this time.

The storm swept through almost all of South Dakota as well as the states of in Minnesota and Iowa,the consequences were

quite serious; more than 30 000 people

were left without electricity.

Fortunately, people were safe.

That's because the locals are pretty

used to Derecho,but,the occurence of the green sky is something else.

It became a very unusual site.

For the locals, everyone was wondering

'Why did it happen? Was it a bad sign or a

normal weather phenomenon?'

Even though scientists don't have

an exact explanation they,however, have

a few assumptions which sound pretty

convincing.

A green sky is a rare phenomenon.

Most scientists think that this happens

when a powerful storm approaches an

area before sunset or sunrise, then the

the sky will turn green in this area.

NBC meteorologist Bill Karens, who once

faced a similar event himself, suggests

that the green sky appeared because of

the hail before the storm.

First, let's talk about why the sky looks

blue or any other shade, depending on its

mood.The sun simultaneously

carries all the rays of the color

spectrum. It may seem white to us in

general, but it has all the colors of the spectrum.

However, these color waves all have

different lengths, for example, Blu-rays

are shorter than the other ones,

jump away from the ear molecules better

than the red waves, so they reach us

faster

because of this on a regular clear day.

The sky seems blue at the same time, red and orange color

waves are very long and move slower, so

they're usually left behind, but when the

The sun goes below the horizon or rises the

Rays' directions change, and these waves

reach us better

It all means that even if the sun rises,

and sunsets seem red and orange to us in

In fact, there are still blue and green

waves among them, but they have to bounce.

off something to reach us faster and

become deeper than red rays.

Have you guessed what I'm getting at?

This is where the water comes into play.

Clouds are made up of water droplets.

When they become large enough but don't

fall yet, for example, due to strong winds.

They affect how the light behaves in the

sky.

Large, heavy storms Largly consist of

water and hail, and water reflects blue

and green rays.That's the reason why the water in

Rivers and lakes seem bluish-green to

us, although, in reality, it's transparent.

This also includes algae matter.

So there are a couple of factors ass to why

the sky may turn green. Firstly,the sun should be at the horizon level.

secondly, the storm clouds will approach there still must be a

little room for the sun's rays, then barely

noticeable blue rays jump up to storm

Still, if you see a green sky, you don't

need to panic; it doesn't necessarily

approaching; the chances are high, though.

But still, it's not a rule; it can be just

heavy rain or a heavy hail

In other words, if you see a green sky,
