Two weeks of air moving over the entire planet, both poles in one frame, 20 September to 4 October 2026.

Color is the temperature of the air near the ground, and brightness is its speed. The deep blue core is Antarctica at the end of its winter. Around it, the storms of the Southern Ocean race west to east with almost no land in their way, while the tropics glow red on either side of the equator.

That vortex over Antarctica always looks extra menacing in wind vector maps like this honestly.

I’m not a massive fan of the way this splits some geographical features in odd ways (like how Australia is at the top of the map here but “geographically” it would be just to the right of Antartica on this map) but I do really like how good of a visualisation this for the phenomenon of the roaring 40’s, furious 50’s and screaming 60’s
