Look At These Crazy Wave Clouds!


Look! In the sky! It’s a bird! It’s a plane! It’s a cloud that looks like neither a bird or a plane! A wave! It looks like a wave!

High above South Carolina yesterday “wave clouds” rippled through the sky. They are bonkers!

Look at this video:

Now look at this one:

Weather.com has a whole gallery of crazy shots.

What is a wave cloud? WIRED explains:

These crazy clouds that look like a row of crashing waves are known as Kelvin-Helmholz waves. They form when two layers of air or liquid of different densities move past each other at different speeds, creating shearing at the boundary.

“It could be like oil and vinegar,” Chuang said. “In the ocean, the top is warm and the bottom is really cold. It’s like a thin layer of oil on a big puddle of water.”

When these two layers move past each other, a Kelvin-Helmholz instability is formed that is sort of like a wave. Parts of the boundary move up and parts move down. Because one layer is moving faster than the other, the shear causes the tops of the waves to move horizontally, forming what looks like an ocean wave crashing on the beach.

“It really is like breaking waves,” Chuang said. “A wave breaks when the water on top moves so much faster than the water below that it kind of piles up on itself.”

The world is a weird and beautiful place.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
