Every Wikipedia edit, anywhere in the world, in any of 300+ language editions, is broadcast in real time on a public stream at stream.wikimedia.org. Interweath connects directly to that stream from your browser and renders each edit as an atmospheric event over the language's geographic centroid.
A station is one language wiki — enwiki, jawiki, frwiki. Its halo grows with the rate of edits in the last 60 seconds. Pressure is inverse to activity: a quiet station is high pressure, a busy one low pressure. When a station's current rate exceeds its 5-minute baseline by 2× or more, it becomes a storm cell — drawn in red with a swirling animation. The named topic of a storm is just whichever article is being edited most frequently at that moment.
The barometer below the map is the global aggregate — total edits per second, smoothed over the last 30 minutes. It rises during news cycles, drops in the small hours UTC, surges on coordinated edit-a-thons. You'll see it.
The internet has weather. Edits, posts, registrations, deletions — they happen at varying intensities in different places at different times. Sample those rates and the metaphor falls out: pressure, fronts, storms, currents. This is the simplest version. One feed, no backend, runs entirely in your browser.
Future updates may layer in GitHub commit weather, Certificate Transparency lightning, package-registry currents, and forecast extrapolation. The metaphor scales. It's just a question of which feeds you fuse.
