I saw this post recently and it made me wonder what’s going on. If you look in the upper right of the frame as the camera submerges, you can see a little vortex of water whirring about. Even with the awesome power of the wave rolling forward a little tornado of water seems able to stably form. Any idea what causes this phenomenon?

This awesome clip was taken from John John Florence’s "& Again" surf video. What you’re seeing is the vortex motion of a plunging breaking wave. As ocean waves approach the shore, the water depth decreases, which amplifies the wave’s height. When the wave reaches a critical height, it breaks and begins to lose its energy to turbulence. There are multiple kinds of breaking waves, but plungers are the classic surfer’s wave. These waves become steep enough that the top of the wave  overturns and plunges into the water ahead of the wave. This generates the vortex-like tube you see in the animation. Such waves can produce complicated three-dimensional vortex structures like those seen in this video by Clark Little. Any initial variation in the main vortex gets stretched as the wave rolls on, and this spins up and strengthens the rib vortices seen wrapped around the primary vortex. (Source video: B. Kueny and J. Florence)

"I want you to promise me something. If you love someone, you tell them. Even if you’re scared that it’s not the right thing. Even if you’re scared that it’ll cause problems. Even if you’re scared that it will burn your life to the ground. You say it, and you say it loud. And then you go from there."

To the Navajo people of the American Southwest, it means two things: Milky Way, and “that which awaits the dawn”.

I’ll add a third meaning: “That which when viewed at full screen and at high volume causes you to experience unspeakable awe and joy.”

Another stunning time-lapse from Gavin Heffernan (check out one of his previous vids here), this time teaming up with Harun Mehmedinović. There’s nothing like a good time-lapse to showcase not only the majesty of the heavens, but the beautiful perspective on them that Earth’s landscapes provide. Enjoy.
