A mesoscale low‑pressure system spins in the South Pacific Ocean

iss074e0573516 (May 6, 2026) --- A mesoscale low‑pressure system is pictured spinning in the South Pacific Ocean, creating significant swells in the surrounding waters just off the coast of Chile's Patagonia region in this photograph from the International Space Station as it orbited 273 miles above Earth. A mesoscale low‑pressure system is a small to medium‑sized area of lower air pressure—larger than a thunderstorm but smaller than a big weather system—that can create its own local wind, cloud, and precipitation patterns.
