———— know the ———— of the sun halo
●What is a solar corona?
The sun halo is also called a round rainbow
An atmospheric optical phenomenon
The cause of the formation of the solar halo is that it appears high in the sky
Cirrostratus clouds made of ice crystals
The ice crystals in Cirrostratus are the equivalent of prisms
It occurs after exposure to the sun
Physical changes such as refraction and reflection
This creates a huge colored halo around the sun
Known as halo
The halo is usually ring-shaped or arc-shaped
Sometimes there are a lot of them
Colored or white dots and arcs of light
These halos, points of light, and arcs of light are collectively known as halos
The angle of view of the halo radius is usually 22 degrees and 46 degrees
The phenomenon of solar halos can usually be observed with the naked eye
●If there is a sun halo, will it be windy the next day?
Solar halos mostly occur in spring and summer
There is a folk proverb that "the sun is halo and the rain is three, and the moon is halo and the wind is at noon".
This means that if there is a solar halo
There will be rain in the middle of the night
If there is a moon halo
It will be windy in the middle of the next day
This is speculation in the end
Or is there a practical basis?
How long do solar coronations last?
Experts say the length varies
Sometimes up to several hours
Sometimes it's just a few minutes
This and the location of the cloud, thickness, etc
factors
●Reminder: How to watch the corona scientifically?
When the solar halo appears
Do not look at the halo with the naked eye for a long time
so as not to burn the eyes
The correct way to observe the solar halo
It is recommended that you cover your eyes with your hands
Block out the sun
Just look at the halo outside
That way the eyes won't feel uncomfortable
Or block the sun with leaves
View through the leaves
You can also look at it with sunglasses
