AI supercomputers are like digital copies of Earth

Scientists create a "digital twin" of Earth that can predict the weather much faster than conventional services .

The supercomputer system is made by Nvidia , a multinational company that produces graphics processing units (GPUs), electronic circuits that can carry out high-speed mathematical equations, allowing activities such as learning to be performed. machine, a form of artificial intelligence (AI), Live Science reported on April 16. The platform, called Earth-2, contains a suite of machine learning technologies developed by Nvidia and controlled by a supercomputer, providing the processing power needed to do the job. Combined, they create "a virtual replica of a real object or system, in this case the Earth's climate ," said Dion Harris, director of data center product marketing at Nvidia.

The system takes the form of an interactive interface that runs simulations of weather and climate across the planet, allowing users to set various parameters, thereby simulating the weather at different locations at up to a detailed level. 2 km. AI technology is trained on global data sets, providing estimates of climate changes across land, atmosphere and oceans. According to Harris, this system compiles hundreds of observations and reconstructions of Earth's weather and climate over the past 50 years.

Thanks to generative training, AI can quickly trawl through multiple sets of weather and climate data, generate thousands of potential outcomes, and ultimately calculate the probability of weather conditions in a specific location. When it comes to weather systems that can threaten lives and cause millions of dollars in damage, Nvidia's system provides real-time predictions within seconds instead of minutes or days. That could make the difference between life and death in a place like Taiwan, where strong storms are common.

"When a storm warning is issued, the top priority is to minimize casualties through early evacuation ," Harris said. For this reason, Taiwan's weather agency is one of the first to test the Earth-2 system to forecast and plan for extreme weather events this year.

Earth-2's supercomputer can quickly comb through vast amounts of data to build accurate predictive simulations. This can help cities explore the likelihood and intensity of extreme weather such as heat waves in the future, then take steps to mitigate the effects.
