Ok forgive me but I just need gush about Anissa Pierce (AKA Thunder), a DC superhero, because first of all look at her, she’s amazing:

A badass woman of color whose power is to control her own density (which sounds kind of strange at first until you realize that means she can make herself completely invincible and kick everyone’s ass by dropping herself on top of them holy shit)

Not only that but she’s got a medical degree because she wanted to graduate before becoming a superhero so like???? she’s a fucking doctor oh my god

And she’s multilingual (English, French, and Spanish) so that’s amazing

But wait! There’s more!!

She has a girlfriend who is also a woman of color and is also super badass:

That’s Grace Choi, a seven foot tall (so big!!!) Amazonian and Asian-American woman who is clearly amazing. 

Grace is an abuse survivor with superhuman strength, durability, and healing so good luck trying to beat her up, she’ll kick anyone’s ass

So anyway the two of them are cute together and they’re each super awesome LGBTQ+ women of color which is great

Also here they are playing video games because that’s adorable:

How do thunder snows happen?

Thundersnow is pretty cool since we don’t see it often. 

So for anyone unfamiliar, thundersnow is basically lightning that occurs during a snowstorm. In concept it sounds pretty boring, but really there’s only about 6.3 snow events with lightning on average each year nationwide.  

Being so rare, it’s just the sort of thing that makes Jim Cantore more excited than a three year old on Christmas

Lets first breakdown the dynamics of a typical storm that has lightning - so no snow necessary as of yet. Lightning happens after the storm has gained a charge as a result of particles rubbing and colliding against each other in the strong vertical convection greater than 5m/s. The clouds that make up these storms are massive in height, as high as 50,000 feet or more. All of this results in an updraft of moist air from the surface. 

This is a massive contrast to a snowstorm. Snowstorms usually have fairly gentle vertical convection when compared to a summer thunderstorm. Additionally, they’re a lot more shallow in the atmosphere, about 20,000 feet in height usually. The surface being around or below freezing temperatures just doesn’t allow for a massive amount of moisture content and instability. So how do we get the sort of atmospheric movement to match up to a summer thunderstorm? We need strong forcing mechanisms! 

Often if we observe thundersnow we see rather strong conditions working in combination with each other. This can include things like lifting from frontal activity, lake-effect snows, orographic lifting, or even synoptic forcing underneath the trowal in strong occluding mid-latitude cyclones. There’s a number of other mechanisms that play into strong winter storms that can create lightning but these are a few of the culprits we can often point to. 

See trowal

We’ve basically established that thundersnow is most often observed in the most elite of winter storms - blizzards with snowfall rates of 2-4 inches per hour. Interestingly enough, that snowfall decreases your visibility to ¼ a mile and dampens the sound of thunder to a 2-3 mile radius (normal thunderstorms can be heard from much larger distances), so even if you’re in a storm that has thundersnow, you may never notice! 

As an aside, there appears to be evidence that tall buildings and communication towers may reduce the thresholds needed for positive cloud-to-ground lightning in winter storms (see 5.3)

Feel free to ask if you have more questions! 


DARA cameos on her brother’s upcoming music video!

As she moves closer, there’s lightning in the air. You can almost hear the thunder in her laugh; it’s loud and proud and rolls through the air. And when she kisses you all you feel is calm and warm, like listening to the rain covered in blankets. When she’s not there, you’ll still get sunny days, but you’re always waiting for the next storm.
