The current is now being asked to draw its own map
the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images.
the ocean now files its own circulation report.
Context
LangYa 2.0 predicts six marine phenomena: typhoons, extreme rainfall, storm surges, internal solitary waves, mesoscale eddies and sea ice. WenHai is a data-driven, eddy-resolving global ocean forecast system built on a deep neural network with bulk formulae for momentum, heat and freshwater fluxes.
Separately, a Nature Geoscience paper from April 2026 maps ocean currents from geostationary satellites, and its code (GOFLOW) is public.
LangYa 2.0 uses separate specialised models for each phenomenon. WenHai builds air-sea flux formulae into one network to keep eddy variability.
