Chinese scientists claim to have developed the world's most advanced ocean simulation system, achieving a resolution of 0.6 miles (1 kilometer).
This breakthrough sets a new benchmark in global ocean modeling and defies ongoing semiconductor export restrictions imposed by the United States.
The new simulation system, named LICOMK++, was created by research teams from the Chinese Academy of Sciences' Institute of Atmospheric Physics and the Computer Network Information Centre. It offers unmatched precision in modeling how oceans behave and interact with climate systems.
According to China's state news agency Xinhua, the simulator acts like an ocean 'microscope.' It can track detailed processes like ocean eddies and heat transport that were previously impossible to model at this scale. This improvement will drastically improve typhoons, floods, and marine heatwaves forecasting.
This innovation reflects China's growing determination to achieve technological independence in critical areas, especially in the face of tight Western tech embargoes. Despite semiconductor import limitations, the team overcame performance barriers in supercomputing using custom algorithms and optimized programming strategies.
'The key to improving the accuracy of climate predictions lies in an ocean simulator,' the researchers explained. But achieving high-resolution simulations requires enormous computational power. Until now, this has been a major challenge in climate science.
The LICOMK++ system is the first in the world to simulate global oceans at such a fine scale. With this capability, Chinese scientists can help global agencies refine climate predictions and create more accurate models for coastal planning and disaster response.
The ocean plays a vital role in regulating the Earth's climate. It absorbs over 90 percent of the heat generated by global warming and more than 30 percent of carbon dioxide emissions from human activity. Simulating how these processes work is essential for understanding and adapting to climate change.
LICOMK++ has already received widespread recognition. It was awarded the top supercomputing application prize at HPC China 2024, a major event hosted by the China Computer Federation. Last year, it was also one of three global finalists for the prestigious Gordon Bell Prize, the leading international award in high-performance computing for scientific advancements.
A report from the Chinese research team highlighted that weather agencies using this advanced model would gain access to higher-quality data, which could help improve global and regional predictions of changes in the marine environment.
In an article shared on its official social media page last Thursday, the China Meteorological Administration noted that LICOMK++ would also support various public services. These include better planning for coastal disaster mitigation, more effective marine resource management, and improved climate adaptation strategies.
This innovation may serve as a turning point for global climate research. By enabling more precise ocean simulations, LICOMK++ promises to boost scientific understanding of the Earth's climate system and offer new tools to combat climate-related economic losses.
