By now some folks have probably seen early versions of Report Buddy floating around. Holden snagged the first tornado pic with it. Ill be open sourcing the code that started as a personal replacement/enhancment for spotter network and mping. adlyons.github.io/report_buddy.h…

*taps sign* models are just dimensionality reduction machines
ideologies are dimensionality reduction techniques that legibilize the world by invariably discarding certain data, sacrificing nuance for actionability most dangerous adherents of any ideology are those who forget they're using a model rather than perceiving reality directly
In the macro sense, management of incoming solar energy budget on Earth involves trading off between sensible and latent heat. Evapotranspiration in plants and sweat in humans are evolved to utilize that tradeoff as a natural AC. This tradeoff is especially efficient because the…
Humidity Rules Everything Around Me: my belated contribution to the AC discourse Maps below show the dew point in NC: 34C/93F and Berlin: 17C/63F. This is a proxy for the total amount of water in the air, and tells me we have 2.5x more of it than Berlin, which matters because-
On many days in the summer, you can literally see a 1-to-1 correlation between corn production and forecast dewpoint maps

Been seeing many tweets about how cold it's been in coastal CA this summer and wanted to add to this, the sea-surface temps along the CA coastline have been running below average. The PDO moving average over the last year is at its lowest values since the 1950's.
Summer 2025… remains one of the coolest in decades around the San Francisco Bay Area. Why is that the ocean wind is so relentless and so chilly for this time of year? Here’s a look at what’s going on and what looks like yet another cool down inland as we head into next week.…
I really wish this could’ve been at night but I’ve wanted this composition with a landing point for a long time. #azwx

There have been varying meteorological forces behind recent extreme rainfall events, but they are all connected by very unusual amounts of moisture pulsing above the United States. Precipitable water, a measure of the total amount of water in the atmosphere, has been above the…
If you think about it dating/relationships can be boiled down to one simple equation: ∫[d(connection)/dt] * dt Seems trivial, but from this you can see: 1) Online dating is overindexed on d(connection)/dt 2) Extramarital affairs at work are overindexed on the limits on…
