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.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
