The eddy is now being given a 120 day schedule
the eddy is now being given a 120 day schedule: tritoncast keeps kuroshio eddy forecasts accurate past 120 days against 10 before, wenhai beats the best eddy-resolving ocean models with air sea flux formulas built in, and scripps measures surface currents from existing weather satellite images.
the sea now files its own swirl forecasts.
Context
TritonCast is described in arXiv 2505.19432, Advanced Long-term Earth System Forecasting, which tackles instabilities that limit long-term forecasts. WenHai is a deep neural network for forecasting the eddying ocean (Nature Communications, Mar 2025). Scripps reported on Apr 13 an AI approach that measures ocean surface currents from satellite data in unprecedented detail (Nature Geoscience).
The WenHai code is published on GitHub.
TritonCast, WenHai and the Scripps current method match the sources. 'Kuroshio eddy forecasts past 120 days against 10', 'beats the best eddy-resolving models with air-sea flux formulas' and 'from existing weather satellite images' were not confirmed in the excerpts read, so they are unsupported here, not refuted.
'The sea now files its own swirl forecasts' is the author's opinion.

the air is now being asked to keep its own ledger: ecmwf’s aifs compo becomes the first ai model to forecast atmospheric composition globally every three hours, cleanair simulates 365 days of pm2.5 over china in ten seconds, and a unified framework maps six pollutants at one kilometer across the whole country. the air now files its own composition report.

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.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
