The current is now being asked to file its own route map
the current is now being asked to file its own route map: china's langya 2.0 model forecasts ocean temperature, salinity and currents one to seven days out and adds marine phenomenon alerts, a kist ocean deep learning general circulation model reproduces kelvin and rossby waves from wind stress curl, and goflow reads thermal images from geostationary satellites to map surface velocity with no new hardware.
the drift now files its own course.
Context
Chinese Academy of Sciences reported on 8 June 2026 that the Institute of Oceanology released LangYa 2.0 for marine phenomenon forecasting. It says LangYa 1.0, launched in late 2024, forecast ocean temperature, salinity and currents for one to seven days, at an efficiency 10,000 times that of conventional methods, and that version 2.0 goes further to where a vortex might form and when a storm surge will arrive.
KIST-Ocean is a deep learning based global three-dimensional ocean general circulation model (PMC, arXiv 2508.10908). The abstract says it reproduces Kelvin and Rossby wave propagation and vertical motions induced by wind stress curl, tied to ENSO-type dynamics. GOFLOW is in Nature Geoscience (April 2026): a deep learning framework that uses geostationary thermal imagery sequences to produce hourly, high-resolution surface velocity fields capturing submesoscale circulations, with code at ksr-ocean/goflow.
The one to seven day range is the CAS description of LangYa 1.0. The note attaches it to LangYa 2.0 together with alerts, and the excerpt read does not restate the horizon for 2.0, so the 2.0 horizon is unsupported here, not refuted. GOFLOW 'no new hardware' matches its use of existing geostationary thermal imagery. The 10,000 times efficiency is the institute's own claim.
