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.
Storm cells that persist for 90+ seconds are recorded — they get a permanent name (the most-edited article), a permalink, and an entry in the Recent Storms log on the right. The log survives across visits. Storms can be linked, archived, and revisited. Browse all recorded storms.
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.
