China's LangYa 2.0 AI predicts ocean's future, reveals secrets of the deep

Chinese scientists have unveiled LangYa 2.0, an artificial intelligence system designed to predict the future of the oceans with unprecedented accuracy. Unlike its predecessor, which focused solely on sea temperature, LangYa 2.0 can forecast the formation of oceanic eddies and the timing of storm surges hitting coastlines.

The new AI system, developed by the Chinese Academy of Sciences (CAS) and introduced at the China Digital Earth Conference in Qingdao, goes beyond basic predictions of temperature, salinity, and currents. It is engineered to anticipate six critical marine phenomena that have historically posed significant threats: typhoons, extreme rainfall, storm surges, internal solitary waves, mesoscale eddies, and sea ice movement.

LangYa 2.0's capabilities were showcased in its ability to predict Arctic sea ice extent in September 2025. In an independent validation by the Sea Ice Prediction Network, an international consortium focused on Arctic sea ice forecasting, LangYa 2.0 ranked first. This accuracy is crucial in the polar regions, where even minor prediction errors can impact the safety of vessels navigating through ice floes.

The AI achieves its remarkable precision by processing massive datasets, integrating satellite imagery, atmospheric data, ocean conditions, and historical records of past events. It identifies complex patterns that are often imperceptible to human analysis, including rapid intensification of typhoons and sudden shifts in their trajectories. The developers aim for LangYa 2.0 to provide timely warnings, enabling coastal cities and offshore operations to prepare for impending disasters.

Version 1.0 only told the sea temperature. Version 2.0 tells where eddies will form and when storm surges will hit the coast.
