Good morning!
Last week we talked about aphelion and this week I've got something I call #WednesdaysWord (an obviously extremely creative name for a subsidiary of #ScienceBehind).

So let's do some science, shall we?
#STEMeducation #STEMed
Last week, we spent time in space so let's bring it a little closer with noctilucent clouds

☁️ (the clouds don't really look like this but twitter emojis just ain't there yet so we make do 🤷🏾‍♀️)

So where exactly do these clouds form? It's in an area of the atmosphere called the mesosphere

We live in the troposphere and that's where our weather happens. Noctilucent clouds don't produce any weather, however

#sciencebehind #STEMed #stemeducation Image
Okay so you're probably wondering... "what do these clouds look like?"

Friends over at @NWSReno tweeted this out last June:



#sciencebehind #STEMed #stemeducation
This time of year is the best time to see noctilucent clouds but your chances of seeing them closer to the equator.

Norfolk/VB latitude: 36.8°N
NYC: 40.7°N
Atlanta: 33.7°N

BUUT that doesn't it's impossible farther south!
#STEMeducation #stemed #sciencebehind #13newsnow
I know that was a bit of time between tweets but my internet died and I got a snack while it came back up. If we gonna keep it a hunnit.

🙃
So no... noctilucent clouds aren't aliens 🚫🛸 BUUT they are part extraterrestrial as some are formed from meteors (which burn up in the atmosphere, leaving dust)

"Extra" = outside
"Terrestrial" = relating to earth

#13newsnow #STEMeducation #STEMed #sciencebehind Image
While noctilucent clouds can be formed from space scraps, volcanic ash and man-made particles can also reach those heights in the atmosphere.

That's it for this week's #ScienceBehind ☄️
Have a great day everyone! Check out the full thread for cool pics

While looking up the origin of the word noctilucent, this song's chorus popped in my head.

So good morning, @Beyonce

It's Wednesday so it's time for Wednesday's Weather Word (an exclusively online subsidiary of the #ScienceBehind series)
Today's word is "analemma"

#13newsnow #STEM #STEMeducation #STEMed #astronomy
Our friends (because we're all friends in science) at Stanford put together this cool site with some analemma plots from Greece ☀️

Well.. wouldn't the position of the sun remain the same all year?
No! And that's thanks to the combination of the Earth's tilt and our non-circular orbit around the sun.

The sleeveless police really are something else.

Before you press 'send' - Would you say those things to my coworkers who are shaped differently (read: thinner) than me?
I'm here to do the WEATHER for Hampton Roads' most accurate forecasting team.
Not have my body picked apart by strangers.

Y'all really wouldn't walk up to a stranger on the street and say those things. Why y'all walking in my inbox/mentions?
Also... there are million other more important things you could be doing rather than tweeting, emailing and messaging me.

Drink some water.
Donate to charity.
Grease your elbows.

So I didn't have a Wednesday Weather Word (a subsidiary of the #ScienceBehind franchise) yesterday. So here's one for you on this (not) Wednesday: #BlueMoon

Yes I know this is astronomy not weather but it's timely so stick with me here
#13newsnow #STEM #Astronomy #fullmoon
Check out this stellar (or should I say 'lunar'?) photo on our Skyview from this morning.

This month we have TWO #fullmoon, the first is today's #HarvestMoon and the second, a rare Halloween Blue Moon.
#13newsnow #STEM #astronomy
Last time there was a #FullMoon on #Halloween visible across the world was 76 years ago in 1944! Most people should be able to see it, weather permitting

The next time we may see a spooky full moon is 2039 as a full moon occurs on Oct 31st every 19 years

Good morning! Someone sent me a photo to ID last week and I thought it'd be a perfect time to bring back Wednesday's Weather Word (a subsidiary of #ScienceBehind)

#13newsnow #STEMeducation Image
Hard to spell
Difficult to say (at least for me)
And sometimes even challenging to see.

This sight is usually seen better around sunrise or sunset, due to the scattering of light during those times.
#STEMeducation #ScienceBehind
Anticrepuscular rays are often dimmer than their counterpart: crepuscular rays

The latter term comes from the Latin for "twilight". Crepuscular rays occur when sunlight streams through breaks in the clouds (some other objects can cause this, too)

each step of your life really prepares you for the next.
i'm sitting here thinking about how #isaias affected us in VA/NC and how if i never moved to Iowa, i might not have gotten the level of tornado/severe weather experience to prepare me for tropical coverage.

as tough as it was out there, i have no choice but to be grateful 🙏🏾
believe in the process even if you don't know what you're believing in or what's on the other side.

you'll look back on everything with near tears in your eyes.
