A new artificial intelligence breakthrough could revolutionise weather forecasts, its creators say. The new technology, built by Google Deepmind, allows for 10-day weather forecasts to be produced in just a minute. And it does so with unprecedented accuracy, Deepmind said. The forecasts made by the GraphCast system are not only more accurate but produced more efficiently, meaning they can be made more quickly and with fewer resources. It can also help spot possible extreme weather events, being able to predict the movement of cyclones and provide early alerts of possible floods and extreme temperatures. Google therefore says it could help save lives by allowing people to better prepare. At the moment, weather forecasts usually rely on a system called Numerical Weather Prediction, which combined physics equations with computer algorithms that are run on supercomputers. That requires vast computing resources as well as detailed expertise by weather forecasters. The new system is one of a range of technologies that instead use deep learning. Instead of looking at physical equations, it learns from weather data and then uses that to model how the Earth’s weather changes over time. Creating the model was intensive, since it required training on decades of weather data. But now that it is created it could vastly reduce the resources required for predicting the weather: 10-day forecasts take a minute on one machine, a process that might otherwise take hours and use hundreds of machines in a supercomputer. In use, the system was able to provide more accurate forecasts than the gold-standard traditional system in 90 per cent of tests, its creators write in a paper newly published in the journal Science. What’s more, the system is able to spot extreme weather events despite not being trained on it. In September for instance it had predicted the path of Hurricane Lee nine days before it arrived, compared to six days for traditional forecasts. Deepmind noted that GraphCast’s prediction of extreme temperatures could be particularly useful given the climate crisis. The system can predict areas where the heat will arrive above the historical top temperatures, allowing people to anticipate heat waves and prepare for them. The company will also open source the system so that it can be used by others. That may help with other new tools and research to help tackle environmental challenges, Deepmind said.

Researchers have invented a new battery that they claim could have profound implications for the future of energy storage and renewable technologies. The lithium-based redox-flow battery, developed by a team at the University of Cincinnati, could prove crucial for wind and solar operations, where large-scale batteries are needed to store energy during times of overproduction and release it when production drops off. “Energy generation and energy consumption is always mismatched,” said Jimmy Jiang, who led the research at the University of Cincinnati. “That’s why it’s important to have a device that can store that energy temporarily and release it when it’s needed.” The novel design removes the membrane that separates the positive and negative sides of the battery, which is one of the most expensive parts of this type of battery and has previously hindered development. The membrane-free battery exhibited high voltage and energy density that could potentially meet the demands of large-scale green energy operations at an economically viable cost for the first time. “This design significantly decreases material costs,” said Soumalya Sinha, a visiting professor at the University of Cincinnati who was involved in the research. “We’re trying to achieve the same performance at a cheaper cost.” The team has submitted patent applications for the design, which Dr Jiang said will herald a “battery revolution” within the next 20 years. “I am confident about that,” he said. “There is a lot of intense research going into pushing the boundaries of battery performance.” The research was detailed in a paper, titled ‘Development of high-voltage and high-energy membrane-free nonaqueous lithium-based organic redox flow batteries’, published in the journal Nature Communications.
