Polar Vortex: The Stratosphere, Watched

Why it surfaced

This is unusually specific, and unusually clear about its mechanism: a four-times-daily Antarctic view follows the chain from 10 hPa winds roughly 31 kilometres up to the surface temperature people actually feel. The site is also candid about what is not built yet, promising sudden-warming records, atmospheric coupling, cold-air outbreak maps, and a three-dimensional vortex render without pretending placeholders are data.
