Over the past two summers, I've been fortunate enough to experience polar days in Tromso and Rovaniemi...I'm not so keen to experience the polar nights of winter though!
Auroras occur predominantly in polar regions rather than tropical regions due to the interaction between charged particles from the sun and the Earth's magnetic field. Here's why: 1. **Magnetic Field Alignment:** The Earth's magnetic field lines are more concentrated near the magnetic poles (north and south poles). This concentration channels charged particles, primarily electrons and protons, from the solar wind toward the polar regions. 2. **Solar Wind Interaction:** The solar wind, which consists of charged particles emitted by the sun, interacts with the Earth's magnetosphere. When these charged particles are funneled along the magnetic field lines towards the poles, they collide with gases in the Earth's atmosphere. 3. **Atmospheric Excitation:** When charged particles from the solar wind collide with gas molecules in the Earth's atmosphere, particularly oxygen and nitrogen, they transfer energy to the gas molecules. This excites the atoms or molecules, causing them to emit light as they return to their original energy state. The different colors of auroras are due to the specific gases being excited and the altitude at which the collisions occur. 4. **Polar Darkness:** Another factor contributing to the visibility of auroras in polar regions is the extended periods of darkness during winter months. With fewer daylight hours, polar regions have more opportunities for observing auroras compared to tropical regions, where nights are shorter and less frequent. In contrast, tropical regions are closer to the equator and experience weaker interactions between the solar wind and the Earth's magnetic field. Additionally, the atmosphere at lower latitudes is thicker, which can hinder the visibility of auroras by scattering and absorbing the light emitted during the auroral displays. Therefore, while auroras can occasionally be observed at lower latitudes during periods of heightened solar activity, they are most commonly seen in the frigid polar regions.
fun fact the sun doesn't go higher than 3 degrees, hence its all day this golden sun. for comparison, in America, the sun reaches the most around 25 - 30 degrees in winter
hebneh Ok Sun/01/31/2021 at 25:29 Also, Ik that it’s technically Mon/02/01/2021 at 01:29, but I’m still awake at night, so it’s still Sun/01/31/2021, so I just call it 25:29 so that you know that I mean staying up past 23:59 and not the thing that happened 24 hours ago. Also, that’s one of the advantages of 24 hour time btw especially when it’s midnight exactly. And I don’t mean that you use a certain one because I have no idea, but rather that I was just saying that in general.
We have a blizzard here in NY rn, and it makes the sky pitch white (it’s more like very light grey because it’s night, but still) with all of the cloudiness and especially because the ground is already covered by now, it literally looks as bright as Civil Dusk or slightly brighter like the darkest part of Civil Twilight when it’s about to end in the afternoon (or Ig evening if it was summer, but rn that’s in the afternoon), and when it blizzarded on Wed/12/16/2020 at 14:xy going into Thu/12/17/2020 and then stopping early in the morning at around 8:xy, it just stopped getting darker around Civil Dusk, and this time, it was just 100% cloudy and didn’t start until sometime after the sunset, and it didn’t actually get like this 23:xy-24:xy/00:xy of Feb 1, so it just got brighter out. I’m definitely looking forwards to playing in the snow tmrw and riding my sled btw.
Peoples who live closer to the North Pole than most of humanity have adapted to the dark better than other peoples. Regardless of which continent they are in. Most of all in marine areas in the North. Like when spending months on large ships which have good enough ice breaking capabilities too.
Vuoggatjålme this Sweden, it was never experience that polar night for 24 hours, sunrise in December at 10:48 AM and sunset 12:57 PM, for 2 hours and 9 Mins and in summer for the midnight sun
It's actually quite bright for at least 5-6 good hours. The reflective white snow is really helpful too, despite the thick clouds.

The clouds you can only get in the Arctic. Lovely
I am at about 45 N, and we get clouds just like that all the time in the winter. But not in the summer.
Those clouds are so boring compared to the summer ones.
Great video! it's absolutely beautiful...
Great video! Thanks for sharing. Also interesting how the moon moves "horizontally" at the end of the video
really puts in perspective how the earth works. Beautiful
Thanks for sharing such an awesome view of your land. Best wishes!

The crescent moon is a bit higher in the sky after sunset. But a full moon would be up all night in the winter.

0:16 Good Morning!
1:05 Good Afternoon!
1:30 Good Night!
It’s still good afternoon at the end & just getting darker out because it’s the winter.

I want to sit there for hours and just watch the clouds

Very nice!
I'll stay down here at 20 degrees latitude, thank you.
But don’t forget about the fact that it balances out in the summer plus more when the sun is above the horizon for the entire day.
@@nabranestwistypuzzler7019 I know the sun never sets in the summer...but I'll still stay down here at 20 degrees latitude.

I live at 40 degrees latitude btw.

Pls add time also
omg that moon at the end going sideways that's so weird

nice, what a luck to live there!

Stunning!
Wow..
Wow
Summer timelapse please.. 😀
It would just be endless daylight for six weeks solid.
@@danielward67 Of course, but timelapse of 24 hrs would help us understanding how it looks like ✌️
So the sun never gets above the horizon?
It does its just that it's so low
@@Mrmakeyoumad How do you know? At 12:00-13:00 there's no sun, no shadows cast. At 14:00 it's becoming darker already. I want the author to answer me.
@@Mrmakeyoumad no, the sun does not cross the horizon on the winter solstic in polar circles
By low i meant only an inch above the horizon I wasn't sure....
@@Mrmakeyoumad nah, it's more like some centimeters below the horizon, there's still some light though
Can you believe what happened in Sweden last night? _SWEDEN!_
Wow nice
No polar night at all
😂❤❤

Certainly not very tropical
I wonder how big a city will be built there in 100 years "Why are there so many lil' lakes?"
