Friday, October 30, 2026 Kelvin-Helmholtz Clouds at Sunrise    

    Martin has been waiting for this ever since we moved in! He’s seen one or two waves, but not enough to see clearly that they were Kelvin-Helmholtz clouds

There they are in the red oval!

Here’s how they form. The wind above, the light blue arrows, is moving faster than the wind below, so you get the swirls forming. This is from Wundergound.

They show up better in a movie!

We had to go shopping this morning, so we ended up at the bottom of the Sea of Clouds.
