Hi, guys!
Today is
Sunday. Finally, I’m at home. In the past few weeks, I was rarely at home on
Sundays because busy, busy, busy. So, when school allows me to stay at home on
Sunday, I choose to spend it by getting tasks done. I’ve been rather productive
today, which is so not me, so yeay!
Now, I want
to tell you about natural phenomenon. Natural phenomenon is an observable event
which is not artificial, it’s real. And based on some researches I’ve done, all
natural phenomenon is beautiful, breath-taking, left me in awe. But, there’s
this one natural phenomenon which I like the most. It’s called light pillars.
Some of you
must be confused. What’s that? What does it look like? Is it similar to pillars
at buildings?
Well, this is
the light pillars.
Beautiful,
right?
How does the
light pillars happen? I’m gonna explain this with an essay!
Light pillars is a visual phenomenon created by the reflection of light from ice crystals
with near horizontal parallel planar surfaces. Generally seen in
cold, arctic regions, light pillars are an optical phenomenon where columns of
light can be seen emanating from below or above a light source. The light pillar looks like a thin column that extends vertically above and/or below the
source of light.
Light pillars caused by the sun are called solar
or sun pillars. When the light source is the sun, light pillars are
usually seen when the sun is near the horizon. It normally forms an arc
that extends from five to ten degrees beyond the solar disc. While those
caused by the moon’s light are called lunar or moon pillars.
Light pillars are a little bit
different. When most of natural phenomenons are not man-made, light pillars can
be formed by man-made light sources, such as streetlights. Because
the ice crystals in the atmosphere reflect the source light, light pillars tend
to take on the color of the light source, such as blue or red.
Light pillars have also been known to produce UFO reports. Niagara Falls is
one such area, where the mist from the Niagara Falls causes the phenomenon to
appear frequently during the winter months, where the ice crystals interact
with the city's many upward facing spotlights to create prominent light pillars.
(Light pillars in Laramie, Wyoming)
(Sun pillar in San Fransisco, California)
I personally
haven’t seen any light pillars yet, even though there are a lot of streetlights
in my town. But, I hope one day I can see it with my own eyes!
That’s all
from me. I have to study Math because Math exam will be held tomorrow! OMG OMG
OMG OMG OMG OMG. Quadratic equations and inequalities, please be nice to me!
See you in
another post~
